Anthony Joshua's return to the ring on Saturday to face Jermaine Franklin is a bout where both have plenty to prove.
Back-to-back defeats to Oleksandr Usyk saw Joshua lose his heavyweight titles, while leaving him with three defeats from his last five bouts.
Franklin, meanwhile, was undefeated and on a meteoric trajectory with 21 victories in a row, including 14 knockouts, before his unbeaten run came to a close at the hands of Dillian Whyte in November at Wembley – his first test outside the United States.
With Joshua in need of a win to stop the rot and Franklin looking to show his worth at this level, their clash at the O2 Arena is one where defeat does not bear thinking about.
Contender or pretender?
Dominating the heavyweight scene for years, the AJ of old was completely lost in the two defeats to Usyk which, although both went the distance, were bouts where the British Olympian never truly looked capable of victory.
The 2019 defeat to Andy Ruiz Jr. was a shock, requiring Joshua to come back six months later to reclaim his belts, but the same cannot be said about Usyk, who was on top throughout almost every round across the pair's two meetings.
Now, the big question is whether the downward spiral will continue, or whether Joshua can force his way back into contention with the heavyweight elite in a period of great change, with the old guard not getting any younger and fresh blood creeping into contention.
For now, Joshua remains in the conversation. Discussions for a fiercely-anticipated all-British bout against Tyson Fury fell flat but Joshua has been touted for a meeting with Deontay Wilder later this year.
Defeat to Franklin, however, would hit hard and would see Joshua's recent record extend to four losses in six fights, not the sort of calibre required to remain at the top of the game, with some already suggesting that such a loss should result in AJ hanging up his gloves, including the man himself.
Franklin's rise
For many, facing Whyte is seen as an entry test into the heavyweight elite, with the Brit having faced the majority of the division's top fighters – including Fury, Joshua, Derek Chisora and Alexander Povetkin.
Defeat to Whyte in November was a blow for Franklin, a majority decision ending the 21-fight win streak, and he is now looking to prove his credentials outside the US by taking a significant scalp in the form of Joshua.
What Franklin lacks in experience, he certainly makes up for in confidence, declaring he will either secure a knockout win or "brutally" dominate the fight.
"If it's not a knockout then it will be a domination brutally. I'll go at him, see what he's going to do and see if I can make him make mistakes early," he said.
Coming out the blocks flying may be the best approach for Franklin, quickly putting the pressure on Joshua and silencing the home crowd, particularly with AJ unable to muster a response in similar circumstances against Usyk.
Pound for pound
Though Joshua boasts height and reach advantage over Franklin, that may not provide a significant indication on the match up given AJ had similar upper hands over Usyk, and a bout may well go the full distance.
Four of Joshua's last seven fights have gone 12 rounds, including three of the last four, and the knockout dominating AJ of old seems to have been lost in the latter years of his career.
Franklin is in a similar position, with just one knockout victory in his last six – having had 14 KO wins in his first 16 professional fights.
Prediction: Joshua wins on points
After an unwelcome international break the view of many, Premier League football returns this weekend with plenty to decide at both ends of the table.
A gruelling clash between title-chasing Manchester City and top-four hopefuls Liverpool kicks things off on Saturday, with league leaders Arsenal hosting Leeds United later in the day and potentially having the opportunity to extend their lead at the summit.
Bukayo Saka is once again one to watch at Emirates Stadium, having maintained his fine form over the international break on England duty, and it would be wise to draft him into your fantasy squad if he is not yet in the side.
Elsewhere, Kai Havertz's resurgence is one to keep an eye on, while Danny Ings and Jack Harrison are also worth a punt.
Using Opta data, we've highlighted exactly why that quartet should be on your hit list.
Bukayo Saka (Arsenal v Leeds United)
The Hale End graduate is the only player in the Premier League to have hit double figures for both goals (12) and assists (10) this season, with Saka in particularly devastating form at Emirates Stadium.
Overall, 14 of his 22 goal involvements have come in north London, standing behind only Erling Haaland (23) for the most direct goal involvements at home in the Premier League.
Last time out against Crystal Palace, Saka scored twice and contributed an assist to help Arsenal maintain their title charge, then carrying that form into England duty and scoring against Ukraine at Wembley.
Kai Havertz (Chelsea v Aston Villa)
Linked with a move to Bayern Munich at the end of the season following Thomas Tuchel's appointment in Bavaria, Havertz has hit a fine vein of form at a crucial stage of the season in Chelsea's top-four bid.
Seven goals this season puts Havertz just one shy of his tally from last season, while he enters the clash against Aston Villa having scored in each of his last two Premier League appearances – meaning he could score in three consecutive games for the first time since March 2022.
No player has been involved in more goals under Graham Potter than Havertz (six goals, one assist), scoring twice the amount as Chelsea's next leading scorer under the Englishman (Mason Mount, three).
Danny Ings (West Ham v Southampton)
Ings has established a fine record of haunting his former employers in the Premier League, having been directly involved in 10 goals in his last 14 such matches (seven goals, three assists).
That includes involvement in three goals in his last two appearances against Southampton (one goal, two assists), who may wonder what might have been had he been in their ranks in the fight for Premier League survival.
Since January 21, no West Ham player has a higher goals-per-game ratio (0.55) or expected goals (0.56) return, while only Jarrod Bowen (6.43) and Said Benrahma (5.29) have more touches in the opposition box per 90 minutes than Ings (4.66).
Jack Harrison (Arsenal v Leeds United)
With six assists over the course of the season, Harrison ranks sixth across the entirety of the Premier League in that regard, with only Christian Eriksen (seven), Mohamed Salah (seven), Leandro Trossard (eight), Saka (10) and Kevin De Bruyne (12) having more.
In Leeds' bid for survival, Harrison has been the catalyst in pushing the club away from the bottom three and travels to Emirates Stadium having scored in consecutive Premier League matches.
Only Rodrigo (12) has been involved in more Leeds goals this term than Harrison (nine), while nobody has created more chances for the Yorkshire side than the midfielder (41).
Giannis Antetokounmpo was not surprised the Milwaukee Bucks lost to the Boston Celtics due to his team's approach to Thursday's game and warned their rivals would "kick our a**" again if they repeated the performance.
The Bucks retain a two-game lead over the Celtics at the top of the Eastern Conference but suffered a humbling 140-99 defeat in the teams' final meeting of the regular season.
Milwaukee will expect to meet Boston again in the playoffs, and Antetokounmpo hopes they will "change some stuff" for that matchup.
He bemoaned the Bucks' attitude in their home loss, saying: "We know what the deal is. It's not hard to understand. If you're not focused, if you don't play hard, they're going to kick our a**. Simple as that.
"There's no level of concern. It's a fact. Now you have this in your head, and it's up to us to see how we're going to deal with it.
"Are we going to go and play the same way? If we play the same way, we'll have the same outcome.
"We've got to change some stuff. We've got to compete. We've got to have some pride."
The Celtics have lost ground in a month in which they have gone 9-6 – to the Bucks' 11-5 – following a number of unexpected defeats.
But Boston continue to respond well to those setbacks, the latest being this week's loss at an undermanned Washington Wizards.
"We've been pretty consistent all year long for the most part," said two-time All-Star Jaylen Brown. "We probably should be closer to 60 wins at this point, but we're a better team than we were last year. We've won more games than we did last year.
"Overall, we haven't dropped the ball; we might have lost some games, but we haven't let a bad game turn into a bad two weeks or a bad month. We've been able to bounce back."
Nikola Jokic sat out the Denver Nuggets' loss to the New Orleans Pelicans as an "ultra cautious" step to protect the two-time MVP ahead of the NBA playoffs.
The Nuggets were beaten 107-88 and have lost their last four matches in which Jokic did not play. He missed this one with a calf injury that appears to be a minor problem.
On this occasion, Denver turned in a largely shabby display in the home loss, proving especially dire from three-point range where their 4-of-28 shooting pointed to a clear deficiency.
Sitting top of the Western Conference, three games ahead of the Memphis Grizzlies, Denver could afford to let Thursday's game get away from them.
The playoffs are approaching, so it was a night where coach Michael Malone felt Jokic needed a rest.
When assessing afterwards how the game went so badly wrong for the Nuggets, Malone said: "Well, Nikola didn't play."
He expanded on his reasons, but it is clear Jokic's unavailability was a major factor behind the team's performance.
Once again, Jokic is a leading contender for MVP honours, chasing a hat-trick of consecutive individual accolades.
The 28-year-old Serbian is averaging 24.9 points per game, plus 11.9 rebounds and 9.9 assists, and it looks to be between him and Joel Embiid for MVP, albeit with Giannis Antetokounmpo a potential dark horse.
Malone, quoted in the Denver Post, said before the game began it was a smart move to give Jokic a rest, following his triple-double against the Philadelphia 76ers earlier in the week.
"Yeah, I think it's just been something kind of brewing a little bit," said Malone.
"He was able to get through the Philadelphia game. In practice yesterday he didn't do a whole lot. Obviously, being ultra cautious with where we're at in the season. If there's any doubt, we're going to definitely err on the side of caution with seven games remaining in the regular season."
Premier League leaders Arsenal went into the international break with an eight-point advantage, and the Gunners will be hoping for a favour from Liverpool on Saturday.
Before Arsenal host strugglers Leeds United, Liverpool travel to the Etihad Stadium to face second-placed Manchester City.
Pep Guardiola's side have a game in hand on Arsenal, but surely they must beat the Reds to give themselves a realistic chance of retaining the title.
Elsewhere, there are more huge fixtures at the bottom of the table, including West Ham v Southampton, while Newcastle United and Manchester United play in a repeat of February's EFL Cup final.
Manchester City v Liverpool
Liverpool, who won the reverse league fixture 1-0, are looking to complete the league double over City for what would be just a second time in the last 17 seasons, previously doing so in Jurgen Klopp's debut campaign in 2015-16.
Mohamed Salah has scored in all three of Liverpool's games against Man City this season, in the Premier League, Community Shield and EFL Cup. The last Liverpool player to score in four different games against an opponent in a single campaign was Ian Rush, netting in five meetings with Everton in 1986-87.
Erling Haaland has scored 42 goals in all competitions for City this season, including six hat-tricks (all at the Etihad). Only two players have scored more in a single campaign for a Premier League club (since 1992-93) – Ruud van Nistelrooy in 2002-03 and Salah in 2017-18 (both 44).
Best bet – City to avoid defeat: City have lost just one of their last 13 Premier League home games against Liverpool (W7 D5), going down 4-1 in November 2015 under Manuel Pellegrini. Guardiola's team have won their last three top-flight games, but have yet to win four in a row this season.
Long shot – Liverpool to win: Liverpool have won more Premier League games against reigning champions than any other side (23). They are aiming to achieve their first such double since 2013-14, beating Manchester United 1-0 at home and 3-0 away. However, they have taken just 12 points from their 13 Premier League away games this season (W3 D3 L7), compared to 30 at home.
Opta prediction: Despite the fierce rivalry over recent years, City are the big favourites for this game, with Opta's supercomputer ranking their chances of victory at 50.9 per cent. The draw is at 26.4 per cent, with Liverpool handed a 22.7 per cent chance of success.
Arsenal v Leeds United
Leeds have won just two of their 23 Premier League games against the league leaders (D9 L12), though both victories came away from home (v Middlesbrough in August 2000 and Man City in April 2021). They have lost all four such games against Arsenal by an aggregate score of 14-2.
Arsenal have won their last six Premier League games, their joint-longest such run under Mikel Arteta. They last won seven in a row between August and October 2018 under Unai Emery.
Arsenal’s top scorer in the Premier League this season is Gabriel Martinelli with 13 goals. The last player to score more while aged 21 or under in a single campaign in the division was Dele Alli in 2016-17 (18).
Best bet – Bukayo Saka to score or assist: Only Erling Haaland (33) and Harry Kane (23) have been involved in more Premier League goals than Saka this season (22), with the winger the only player so far to reach double figures for both goals (12) and assists (10).
Long shot – Leeds to keep a clean sheet: Since a 0-0 draw in their first Premier League away game against Arsenal in February 1993, Leeds have not drawn or kept a clean sheet in any of their subsequent 13 league visits to the Gunners (W3 L10), shipping 31 goals in total.
Opta prediction: Opta do not give Leeds much chance at Emirates Stadium (15.5 per cent). Arsenal are huge favourites, with a 61.6 per cent win probability, while the draw is ranked at 22.9 per cent.
West Ham v Southampton
Coming into this weekend's games, Southampton have picked up the highest share of their Premier League points this season away from home (57 per cent - 13/23). Meanwhile, only Nottingham Forest (77 per cent) have a higher share of points won at home in 2022-23 than West Ham (75 per cent - 18/24).
Southampton have picked up as many points in their six Premier League games under Ruben Selles (8 – W2 D2 L2) as they had in their 17 league matches beforehand (W2 D2 L13).
Sides starting the day bottom of the Premier League have won 11 league matches this season, four more than the whole of last term (seven), and the most in a single campaign in the competition since 2017-18 (12). Southampton have been responsible for three of those victories by bottom-placed sides in 2022-23, a joint-high (also Leicester).
Best bet – James Ward-Prowse to create two chances: Coming into this weekend's games, only Kieran Trippier (49) has created more chances from set plays than Ward-Prowse (35) in the Premier League this season, while the Southampton captain is the only player to create 25+ chances from both open play (27) and set pieces (35) in the division this term.
Long shot – A goalless draw: No other sides have kept fewer clean sheets in the Premier League this season than Southampton (four) and West Ham (five)
Opta prediction: Despite both of these teams struggling, it is West Ham who Opta give 51.4 per cent chance of claiming all the points. Southampton have been responsible for three of the seven victories by the bottom-placed side this season, but the likelihood of them succeeding this time stands at 21.7 per cent.
Newcastle United v Manchester United
Following their goalless draw at Old Trafford in the reverse fixture, Newcastle are looking to keep a clean sheet in consecutive Premier League games against United for the first time since May 1997.
No player has scored more winning goals in the Premier League this season than Marcus Rashford, with nine of his 14 strikes being the winner. Only two United players have ever scored more winning goals in a single campaign in the competition – Cristiano Ronaldo (12 in 2007-08) and Wayne Rooney (10 in 2009-10).
Coming into this weekend's fixtures, only Bournemouth (38), Nottingham Forest (32) and Leicester (30) have conceded more away goals in the Premier League this season than United (27). Indeed, only in four different Premier League campaigns have the Red Devils conceded more on the road – 1999-00 (29), 2001-02 (28), 2018-19 (29) and 2021-22 (35).
Best bet – United to win: United have won more Premier League away games against Newcastle than any other side (14). However, they have lost two of their last five such visits (W2 D1), having lost just one of their previous 13 at St James' Park. Newcastle are winless in six Premier League games against Man Utd (D2 L4), though the last two have both been drawn.
Long shot – Rashford and Alexander Isak to score: Rashford has been involved in seven goals in his eight Premier League starts against Newcastle (four goals, three assists) – only against Arsenal and Leicester City (nine each) has he been involved in more. Isak, meanwhile, has scored six goals in 10 Premier League appearances for Newcastle this season, including three in his last two.
Opta prediction: This could prove a big game in the top-four race, with Newcastle only three points behind third-placed United. The visitors are made very slight favourites (36.8 per cent to 34.2 per cent). The draw is given a 29 per cent chance.
Erling Haaland has done rather well for Manchester City since arriving.
Fine, that may be something of an understatement. The 22-year-old has filled his boots and then some since he moved to the Etihad Stadium from Borussia Dortmund last year.
Haaland has 42 goals in 37 games for City, with 28 of those coming in 26 Premier League appearances.
Pundits will say they had their tongues firmly embedded in their cheeks when some suggested the Norwegian might find English football trickier to conquer despite his domination of the Austrian and German top-flights, but few could have anticipated such a relentless flow of goals.
Those doubts appeared after Haaland's blank against Liverpool in the Community Shield defeat in his first official outing for the club, while he also failed to score in City's 1-0 loss at Anfield two and a half months later.
He did find the net against Liverpool in their EFL Cup fourth-round win in December though, and should he be fit to take the field against Jurgen Klopp's men on Saturday, Haaland will be hoping to get closer to a record that many thought would never be broken.
With 11 games remaining, Haaland is just seven short of claiming the record for the most goals in a single Premier League season, with Andrew Cole in 1993-94 for Newcastle United and Alan Shearer for Blackburn Rovers a year later both managing 34, albeit in campaigns that lasted 42 games.
Haaland is just four behind Mohamed Salah's record for a 38-game Premier League season, set in 2017-18.
So perhaps the question is not 'will he break the record?' but 'when?'
Haaland has missed just one league game so far, and the injury that caused him to pull out of Norway's Euro 2024 qualifiers did not sound particularly serious, so even if he does miss the visit of Liverpool, he still has plenty of time to find the necessary goals.
After all, he scored eight in his last two games before the international break, hitting five against RB Leipzig in the Champions League before another treble against Burnley in the FA Cup.
As they fight Arsenal for the league title, City's remaining fixtures see them face Liverpool (h), Southampton (a), Leicester City (h), Arsenal (h), Fulham (a), West Ham (h), Leeds United (h), Everton (a), Chelsea (h), Brentford (a) and Brighton and Hove Albion (a).
With the leaky defences of Liverpool, Saints and Leicester this season, it would not be a complete shock if he has already reached the magic number of 35 by the time he lines up against Arsenal for a crucial title clash.
In the corresponding fixtures against those 11 opponents, Haaland scored 10 goals (two against West Ham, Leeds and Brighton, one against Southampton, Fulham, Arsenal and Everton, zero against Liverpool, Chelsea and Brentford and he did not play at Leicester), so even repeating his efforts against them will be more than enough.
With 28 goals in 26 league games, Haaland is averaging 1.1 goals per game. That means if he can play in each of City's remaining games, he should reach 40 by the season's end.
That could be asking a bit too much from him, especially considering City also have a Champions League quarter-final against Bayern Munich coming up, and head coach Pep Guardiola has been known to rest his stars for league games once that competition gets to the latter stages.
Continuing the rate though – assuming he continues to play and the re-arranged game at Brighton is not scheduled beforehand – would see him break the record against Leeds on May 7, appropriately a former club of his father.
While reaching 40 might be beyond him – emphasis on "might" – finding the seven required to overtake Cole and Shearer actually seems borderline routine for a player who has produced the numbers he has.
In just the Premier League, Haaland has four hat-tricks, as many as the rest of the league combined (Phil Foden, Son Heung-min, Leandro Trossard and Ivan Toney all on one).
He also doesn't have to worry about opportunities being created for him by his immensely talented City team-mates, having had 43 Opta-defined "big chances" – a chance from which a player would be expected to score – 15 more than the player with the next most (Toney).
Haaland's shot conversion rate of 31.1 per cent is also well above any other player to score at least six goals in the Premier League this season, ahead of Brighton duo Kaoru Mitoma and Pascal Gross (both 26.1 per cent).
He averages a goal every 75.6 minutes, comfortably ahead of Newcastle's Alexander Isak (103.8), Tottenham's Harry Kane (119.3), Leeds' Rodrigo Moreno (123.1) and Liverpool's Roberto Firmino (129).
Former Newcastle and Manchester United striker Cole recently told Stats Perform it "doesn't bother" him if Haaland breaks his record.
"I've said to people it doesn't bother me in the slightest, I don't care. If someone deserved to break that record, go ahead and do it," he said.
"I don't care if he does it. I'll be the first one to congratulate him. Records are there to be broken."
It looks like a record that will indeed go soon, and it may be the first of many that the irrepressible striker shatters.
After his record-breaking 2022 season, there was no one more fitting to hit the first home run of the 2023 campaign than Aaron Judge as the New York Yankees won 5-0 over the San Francisco Giants on Thursday.
Judge, who blasted an American League single-season record 62 home runs last season, lit up Opening Day with the first home-run shot of 2023 in the first inning at Yankee Stadium.
The Yankees outfielder needed only two pitches before launching Logan Webb's sinker over the center-field wall. Judge's blast had an exit velocity of 109.3 mph and traveled 422 feet according to Statcast projections.
Gerrit Cole did the rest on the mound, recording an Opening Day franchise record 11 strikeouts across six scoreless innings.
Gleyber Torres creamed a two-run blast in the fourth inning to open up a 3-0 lead, while Torres scored again from a D.J. LeMahieu single in the seventh.
Judge chimed in with a broken-bat RBI single in the same inning, with Jose Trevino scoring, securing a 5-0 win and initiating "M-V-P!" chants from the home crowd.
Top prospect Anthony Volpe also got a rousing reception from the Yankees faithful, finishing 0-2 with a walk in his maiden start at shortstop.
Jays edge Cards in 19-run, 34-hit epic
The Toronto Blue Jays edged the St Louis Cardinals 10-9 in a wild 19-run 34-hit Opening Day classic where Vladimir Guerrero Jr played a key role.
Guerrero brought home the decisive run with a ninth-inning sacrifice fly for new addition Kevin Kiermaier to score the go-ahead run. Guerrero finished with three RBIs from two hits.
Alejandro Kirk had helped the Jays to a 3-0 first-inning lead with a two-run single on a line drive, after Daulton Varsho drove in George Springer on a double.
The chaotic contest saw the Jays become the first MLB team to allow a go-ahead run in the sixth, seventh and eighth innings on the road and still win since the Boston Red Sox in 1938.
Ohtani sends down 10 Ks in Angels defeat
Shohei Ohtani took the unusual step of calling his own pitches, sending down 10 strikeouts, but it was not enough for the Los Angeles Angels in a 2-1 loss to the Oakland Athletics.
Ohtani threw six shutout innings, allowing only two hits, but the A's capitalized after he exited, turning a 1-0 deficit into a 2-1 victory, scoring two at the bottom of the eighth.
Tony Kemp doubled on a fly ball past Mike Trout in center field with Esteury Ruiz scoring, before Aledmys Diaz's line drive drove in Kemp.
Angels outfielder Hunter Renfroe produced a moment of magic in the fifth inning with a no-look catch, leaving Ohtani stunned.
The Boston Celtics produced a stunning 140-99 blowout on the road against the full-strength Milwaukee Bucks in Thursday's potential Eastern Conference Finals preview.
Although the Bucks did roll out their full team, they were playing their third game in four days and were on the second leg of a back-to-back, and their fatigue showed in a horrible first half defensively.
The Celtics piled on 34 points in the first quarter, and added another 41 in the second to open up a commanding 75-47 lead at half-time. Instead of coming out of the locker room with extra intensity, the Bucks proceeded to give up another 39 in the third period to kill the game.
Boston's All-Star duo were nearly faultless, led by Jayson Tatum's 40 points on 12-of-18 shooting. He finished eight-of-10 from three-point range, and a perfect eight-of-eight from the free throw line while adding eight rebounds and zero turnovers.
Jaylen Brown was just as impressive as he made his way to 30 points on 13-of-20 shooting with five rebounds, five assists and just one turnover, while Sixth Man of the Year candidate Malcolm Brogdon chipped in 14 points (six-of-13), five assists and four steals off the bench.
Bucks superstar Giannis Antetokounmpo led his side with 24 points and seven rebounds through three quarters before sitting out the last, although he was a disappointing 11-of-27 from the field and missed all five of his three-point attempts.
The win pulled the Celtics (53-24) to within two games of the Bucks (55-22) in the race for the Eastern Conference's top seed, and for the best record in the league.
Ingram shows recent improvement is no fluke
New Orleans Pelicans wing Brandon Ingram has performed at an All-NBA level since the All-Star break and continued to shine in a 107-88 triumph over the Nikola Jokic-less Denver Nuggets.
Ingram, 25, posted the first triple-double of his career last Thursday and followed it with a career-high 13 assists on Saturday, and he now has his second triple-double after 31 points (13-of-22), 11 rebounds and 10 assists against the Nuggets.
Across his past eight games, Ingram is averaging 29.6 points, 8.3 assists and 6.3 rebounds while shooting 51.8 per cent from the field and 48 per cent from deep.
The result improved the Pelicans' record to 39-38, leapfrogging the Minnesota Timberwolves into the Western Conference's seventh seed, with Zion Williamson's return potentially imminent after working out on-court prior to Thursday's game.
Elena Rybakina is now one win away from completing the Sunshine Double after defeating Jessica Pegula 7-6 (7-3) 6-4 in Thursday's Miami Open semi-final.
Only four women have ever claimed the Sunshine Double – which requires winning both the Indian Wells Open and Miami Open. Steffi Graf did it in both 1994 and 1996, Kim Clijsters did it in 2005, Victoria Azarenka accomplished the feat in 2016 and current world number one Iga Swiatek did it just 12 months ago.
Rybakina sent a message to the tennis world as she knocked out both world number one Iga Swiatek and world number two Aryna Sabalenka to take home the Indian Wells crown, and she has carried that form into Miami.
After prevailing in three-setters against Anna Kalinskaya and Paula Badosa, the Kazakhstan representative has now rattled off consecutive straight sets victories against Elise Mertens, Martina Trevisan and Pegula to extend her winning streak to 13 matches.
Against Pegula, Rybakina served 11 aces to the American's one, and in the process she became the first woman to serve at least 10 aces during five matches in the same tournament since Serena Williams back at Wimbledon in 2016.
By securing the first-set tiebreaker, Rybakina claimed her tour-leading seventh tiebreaker win of the season, with a perfect 7-0 record.
She will meet the winner between Petra Kvitova and Sorana Cirstea in the final after the Czech veteran emerged victorious 6-4 3-6 6-3 in her quarter-final against Russia's Ekaterina Alexandrova.
The neck-and-neck contest saw Kvitova only narrowly edge the total point count 96-91, but she created nine break points to Alexandrova's six.
Kvitova, 33, is now one win away from her 41st WTA singles final, where she would be seeking her 30th WTA title, and her ninth at the WTA 1000 level. It would be her first at this level since the 2018 Madrid Open, following defeats in the finals of the 2019 Dubai Championships, the 2020 Qatar Open and the 2022 Cincinnati Open.
Justin Lower leads the Valero Texas Open through nine holes with play suspended due to darkness as Padraig Harrington and Matt Kuchar joined the group one stroke behind on Thursday.
The opening round was called off early in fading light, with play having been delayed numerous times in the morning due to fog in South Texas.
Lower, 33, got through the first half of his round, managing an eagle on the par-five 14th hole along with three birdies for a five under start.
Three-time major winner Padraig Harrington, 51, wound back the clock in his 333rd start in his 28th season. The Irishman, playing in familiar conditions, carded a four-under 68 with six birdies.
Fellow veteran Matt Kuchar had a similar round with six birdies and two bogeys for a four-under 68 to be tied for second.
The 44-year-old American and Harrington are alongside South Africa's M.J. Daffue, Mexico's Roberto Diaz and USA's Patrick Rodgers.
Fresh from winning last week's Corales Puntacana Championship, Matt Wallace is in a group of eight players, including Canada's Corey Conners (through nine holes), one stroke behind at three under overall.
Pre-tournament favourite Tyrrell Hatton only got through 10 holes to be two under, while Rickie Fowler and defending champion J.J Spaun were both even after 11 holes.
World number one Carlos Alcaraz made it 10 wins in a row in Miami and kept alive his hopes of a rare Sunshine Double as he beat Taylor Fritz in straight sets in Thursday's quarter-finals.
Alcaraz swept aside the 2022 Indian Wells champion 6-4 6-2 in a lopsided Miami Open contest which lasted only 79 minutes, with the Spaniard breaking Fritz in the opening game of both sets.
Both players hit 20 winners, including 11 each on their respective forehands, but Fritz almost doubled Alcaraz' unforced errors count (28-13).
The 19-year-old was impressive from the baseline and overwhelmed Fritz in the end. The American only won 38 per cent on his second serve.
Alcaraz, who won the Indian Wells title a fortnight ago, remains on track to become the eighth male to win the Sunshine Double (Indian Wells and Miami), with Roger Federer the last to achieve that in 2017.
The Spaniard would join Federer (2005, 2006, 2017), Novak Djokovic (2011, 2014, 2015, 2016), Andre Agassi (2001), Marcelo Rios (1998), Pete Sampras (1994), Michael Chang (1992) and Jim Courier (1991) in achieving the Sunshine Double.
Alcaraz will take on Italian 10th seed Jannik Sinner in the semi-finals, after the duo faced off in the Indian Wells last four a fortnight ago, with the Spaniard winning in straight sets.
In-form Daniil Medvedev progressed to the semi-finals with a 6-3 7-5 victory over American qualifier Chrstopher Eubanks, who had enjoyed a dream run in Miami.
Medvedev has a 27-3 record this season and will pursue a fifth straight ATP Tour final when he takes on compatriot Karen Khachanov in the semi-finals.
Khachanov, who made this year's Australian Open semi-finals, defeated Francisco Cerundolo 6-3 6-2 in 76 minutes.
Daniil Medvedev says he has never started a season this well before following his 27th victory of the year to secure his place in the Miami Open semi-finals on Thursday.
The Russian world number five prevailed over American qualifier Christopher Eubanks 6-3 7-5 to qualify for the Miami semis after falling in the last eight in both 2021 and 2022.
Medvedev's progress comes after his 19-match winning run was ended in the Indian Wells Open final by Carlos Alcaraz a fortnight ago.
The 27-year-old has now won 22 of his past 23 matches and is 27-3 on the season, having won titles in Rotterdam, Doha and Dubai and is now chasing a fifth straight appearance in an ATP Tour final.
"I have never had such a good start to the season," Medvedev said. "A lot of matches won, tournaments won. I am really happy.
"I was disappointed at Indian Wells when my streak ended on the same number as last time. The only thing you can do is begin a new streak and I am happy to bring my form into Miami."
Medvedev will rise up to fourth in the ATP rankings if he lifts the Miami title, with the incumbent Casper Ruud suffering a third-round loss to Botic van de Zandschulp earlier this week.
The 2021 US Open champion is clear atop the ATP standings for most match wins in 2023, with his 27 well ahead of the next best, Cameron Norrie (21-5).
The Russian, who will take on countryman Karen Khachanov in the semi-finals, credited work with mental coaches for his improvement in 2023.
"That's something I want to improve," he said. "For example, talking about Indian Wells, I had my tantrums, which it's not good.
"It can throw you out from the concentration, and it's not a good look anyway, but I managed to still win matches and still be concentrated during those matches."
On the Khachanov match-up, which he leads 3-1 on head-to-head, he added: "I think maybe just a little bit you have to kind of force yourself even more to be focused, and when I say this, it's just because they know your game so well and you know theirs so well.
"I'm almost sure we know how the match is going to go tomorrow, and it's a question of who's going to make the best shot out of [the shots] we're going to play."
Offseason acquisition Justin Verlander has been placed on the New York Mets injured list with a low grade muscle strain near his pitching shoulder.
The Mets made the announcement on Thursday, the Opening Day of the 2023 MLB season, citing a "low grade teres major strain" with the 40-year-old reigning Cy Young Award winner to be reevaluated next week.
Verlander will be able to continue to throw at "moderate intensity" in the meantime, with the pitcher seeking treatment on the issue after Wednesday's bullpen session where his velocity fell.
"This isn't best-case scenario," Verlander told reporters in Miami where he was scheduled to pitch on Saturday against the Marlins. "But I would think this is probably second-best case. Very minimal."
The 2022 World Series champion, who crossed from the Houston Astros in the offseason, said the issue had been lingering.
"Looking back, it's something that was lingering, but it's spring training and it's very normal to work through stuff, so I didn’t give it much credence," Verlander said. "I just thought it was something I was working through. My last start was able to go out and pitch through that, so I got over that hurdle.
"In my bullpen yesterday, I still felt a tiny bit of something. When I looked back, when I thought I was over it and still felt something, I connected the dots and my velocity was down a bit in my last start.
"That was the main thing where I was like 'well something's going on to cause my velocity to be down one or two miles an hour'.
"I've dealt with a lat [lateral injury] before a couple times in my career. It's not something to mess around with at all. I missed three months one time. In my mind it was to be prudent and smart and get it looked at."
Verlander finished 18-4 in a near career-best 2022 season, posting a 1.75 ERA in 175 innings for the Astros. He joined the Mets after they lost Jacob deGrom in a free agency move to the Texas Rangers.
The right-hander watched on from the dugout as the Mets opened their season on Thursday with a 5-3 win over the Marlins.
The New York Knicks will be without Julius Randle for the rest of the regular season as he races to heal from an ankle injury before the playoffs.
The All-Star was hurt in Wednesday's 101-92 win over the Miami Heat, after his left leg landed on Heat center Bam Adebayo's left foot as he pulled down a rebound with 2:40 remaining in the second quarter. He was ruled out at half-time.
Randle, who leads the Knicks in both scoring (25.1 points per game) and rebounding (10.0), has played all 77 games this season, but will miss the final five after the team announced he will be re-evaluated in two weeks.
The timeframe means he would be unavailable for the play-in tournament, but crucially the Knicks (44-33) sit four games clear of the seventh seed Miami Heat (40-37).
Two weeks from now would be just two days before the first round of the playoffs are due to begin, and it appears likely the Knicks would begin their playoff run on the road against the Cleveland Cavaliers in the Eastern Conference's four-five matchup.
It has been a great bounceback season from Randle, who was named to the All-NBA Second Team back in 2021, before his points dropped from 24.1 to 20.1 with all his percentages falling off a cliff in 2022.
The introduction of point guard Jalen Brunson has breathed new life into New York, and has made Randle's job far easier.
With his new partner-in-crime, Randle has set career-highs in scoring, free throw makes and attempts, three-point makes and attempts, and his 46.0 per cent mark from the field matches his best percentage since arriving with the Knicks, all on career-high volume.
