Maria Sakkari laughed off any suggestion of a "Netflix curse" after a comeback win over Diana Shnaider at the Australian Open.

Sakkari, seeded sixth in Melbourne, came from a set down to beat Shnaider 3-6 7-5 6-3 on Wednesday.

That marked the Greek's fifth career comeback win in a grand slam main draw, though her first since the fourth round at the 2021 US Open against Bianca Andreescu, and her first at the Australian Open.

Across this season and last year, Sakkari has played 25 Tour-level matches that have gone the distance, with only Ons Jabeur (26), Belinda Bencic (27) and Aryna Sabalenka (28) having played more three-set matches in the same timeframe.

Sakkari was one of nine players (four from the WTA Tour, five from the ATP Tour) to feature in Netflix's new Break Point series, which was launched on the streaming platform earlier this month.

However, three of those players – Nick Kyrgios, Ajla Tomljanovic and Paula Badosa – had to withdraw from the season's first grand slam due to injuries, while Matteo Berrettini was defeated by Andy Murray in his first-round match.

Yet Sakkari does not believe in such superstitions as a "Netflix curse".

"Netflix curse? I have never heard that," Sakkari said.

"I mean, the only one that I can think of is Matteo, but Matteo lost his match 7-6 on the fifth set. I personally have to say that they only bring us luck, and I enjoyed my time with them because they are nice people.

"Trust me, they are very, very nice. You know, if you let these thoughts and this energy affect you, then it's when bad luck comes.

"I would say that because they are all very nice and they are all very respectful, they have only brought me good luck."

She smiled: "Obviously some tournaments I play badly because I play badly. It's not because of them! But, yes, overall it has been great."

Shnaider, in her first meeting with Sakkari, became the first female qualifier to win the opening set at the Australian Open against a top-eight seeded opponent since Angelique Kerber against Svetlana Kuznetsova in 2010.

Sakkari will face Lin Zhu in the third round, after the latter's win over Jil Teichmann.

The pair have only met once before, in qualifying for the 2016 Australian Open, with Sakkari coming out on top.

Jessica Pegula has been wearing a number three on her outfit at the Australian Open, and she confirmed it is to show support to Damar Hamlin.

Buffalo Bills safety Hamlin went into cardiac arrest during the game against the Cincinnati Bengals on January 2 and spent over a week in hospital, much of that time in critical condition.

Pegula's parents own the NFL franchise as well as the Buffalo Sabres NHL team, and during her second-round win over Aliaksandra Sasnovich in Melbourne, was seen with a number three on her skirt, which is Hamlin's number and became a symbol of appreciation from well-wishers during his recovery.

"I definitely wanted to do something," Pegula said after her 6-2 7-6 (7-5) victory over Sasnovich. "We were kind of figuring out what the Bills and the Sabres were doing, just as far as what was the message.

"I knew they would probably do something and what message were they trying to send. It ended up being [that] the three was the symbol.

“I just thought it would be cool to put on my outfit here. I thought it would be a fun way to kind of connect with the team and then also just show my support."

There had been speculation that the number was related to her ranking, with the 28-year-old coincidentally the WTA world number three heading into the Australian Open, where she is the third seed, but Pegula laughed off the suggestion.

"I saw someone tweet that: 'Why would you put your ranking on your skirt?'. I'm, like, 'No, that’s not why,'" she said with amusement.

Pegula will play the winner of Olivia Gadecki and Marta Kostyuk in round three at Melbourne Park.

Rafael Nadal refused to retire from his second-round match at the Australian Open despite suffering a hip injury in his shock defeat.

The reigning champion and top seed in Melbourne crashed out on Wednesday, going down 6-4 6-4 7-5 to world number 65 Mackenzie McDonald.

Nadal started sloppily in the first set and then pulled up with an apparent upper leg issue after chasing a forehand at 4-3 down in the second, and his movement was clearly hampered from that point on.

The 36-year-old confirmed he aggravated an issue he had been suffering with for a "couple of days" prior to his meeting with McDonald.

Nadal could well have handed McDonald a walkover, but explained that as defending champion, he did not want to go out without a fight.

"I considered all the time stopping, but I didn't ask," he said in a press conference. "I have to know myself, and I tried to keep playing without increasing the damage.

"I was not able to hit the backhand at all. I was not able to run for the ball. But I just wanted to finish the match. That's it.

"I didn't ask them [his team]. I am old enough to take my own decisions. I didn't want to retire, [as] defending champion here. No, I didn't want to leave the court with a retirement.

"It's better like this. I lost. Nothing to say. Congratulations to the opponent. Just try your best till the end, it doesn't matter the chances that you have.

"That's the philosophy of the sport. That's the essence of the sport by itself. I tried to follow that during all my tennis career, and I tried of course to not increase the damage, because I didn't know what's going on."

Nadal, who is the first top seed to go out in the second round of the Australian Open since Gustavo Kuerten in 2001, is unsure as to the extent of his injury.

"I don't know what's going on, if it's a muscle, if it's a joint. I have history in the hip, I had issues. I had to do treatments in the past," he said.

"Now I feel I cannot move. But I don't know till I do the test and all this stuff, I don't know. I don't know.

"I'm tired of talking about it. I understand, but I lost the match. That's it. I tried until the end. I don't know if in good condition I would win the match. I will have better chances without a doubt."

Nadal added that he would be "lying" if he said he had been mentally destroyed by the issue, given the comfort of his life outside tennis.

However, the 22-time grand slam champion is still motivated to return to the court.

"It's a very simple thing: I like what I do. I like playing tennis," he added.

"I know it's not forever. I like to feel competitive. I like to fight for the things that I have been fighting for almost half of my life or even more. 

"It's not that complicated to understand, no? When you like to do one thing, sacrifices always make sense. When you do things that you like to do, at the end of the day, it's not a sacrifice. You are doing the things that you want to do. Sacrifice is when you are doing things that you don't want to do."

The Spaniard conceded another long spell away from the court would be difficult, though.

He said: "Of course it's tiring and frustrating to spend a lot of [this] part of my career recovering and trying to fight against all this stuff all the time.

"I have had seven months playing almost nothing, and then if I have to spend a long time again, then it's super difficult in the end to be in rhythm and to be competitive and to be ready for the fight. Let's see how the injury is, and then let's see how I can manage to follow the calendar."

Mackenzie McDonald produced one of the upsets of the Australian Open on Wednesday as he eliminated defending champion Rafael Nadal 6-4 6-4 7-5 in the second round, with the Spaniard hampered by an apparent leg injury.

There were ominous signs early on as number one seed Nadal had his serve broken in the opening game of the match, and McDonald secured a second break en route to wrapping up the first set.

It was more of the same in the second as McDonald took advantage of some uncharacteristically sloppy play from the 36-year-old, before Nadal seemed to hurt himself.

At 4-3 down in the second set, Nadal pulled up with an apparent upper leg issue after chasing a forehand, and his movement was clearly hampered from that point on.

In typical defiant fashion, Nadal's level rose in the third, hitting 24 winners, but as he improved, so did McDonald, who did not allow Nadal a single break point opportunity.

The 22-time grand slam champion saved break point at 4-4 to hold serve as he tried to get back into the contest, but was unable to repeat the trick in his next service game as McDonald secured the break before serving out to clinch a famous win.

It is the latest in a troubling run of form for Nadal, who received multiple injury timeouts on his way to a seventh loss from his last 10 matches dating back to the US Open.

McDonald will play the winner of Yoshihito Nishioka and Dalibor Svrcina in the third round.

Data Slam: Nadal joins dubious company as top-seed casualty

Nadal is the first top seed to be eliminated from the Australian Open in the second round since Gustavo Kuerten in 2001.

The Brazilian was also a clay specialist, winning all three of his grand slams at the French Open.

The Memphis Grizzlies will get a chance to tie their longest winning streak in franchise history when they host the Cleveland Cavaliers on Wednesday.

Monday's 30-point demolition of the Phoenix Suns extended the Grizzlies' streak to 10, and they are now one victory away from tying the 11-game streak from the 2014-15 campaign starring Marc Gasol and Zach Randolph, which was matched last season.

Over their last 10 fixtures, the Grizzlies have been a juggernaut on both ends of the court, scoring 119.9 points per 100 possessions to sit third in offensive rating, while also boasting the best defense in the NBA, allowing just 106.5.

Meanwhile, the team the Grizzlies overtook to snatch top spot in the defensive rankings was the Cavaliers, who still sit second for the season.

Another key indicator for the true contenders is net rating – which measures how much better a team's offensive rating is compared to their defense – and both of these sides have excelled through the first half of the season. The Grizzlies sit second overall with a net rating of 5.8, while the Cavaliers are third at 4.7.

Two very similar teams, both the Cavaliers and the Grizzlies utilise two defensive anchors in their starting line-up, leaning away from the more prevalent "small ball" roster constructions seen around the league.

For the Grizzlies, Steven Adams is arguably the strongest rebounder in the league while Jaren Jackson Jr leads the NBA in blocks per game at 3.3. On the Cavaliers' side, All-Star Jarrett Allen and defensive prodigy Evan Mobley roam the interior.

While these sides are almost identical defensively, the way they attack on offense, particularly through their star players, could decide their fate.

Grizzlies point guard Ja Morant is, without a doubt, one of the best guards in league history when it comes to finishing at the rim. He is averaging five makes per game within five feet of the basket – the only guard in the league to do so – while converting at a terrific 61 per cent clip.

The problem with that is how well both of these teams protect the basket, as it creates the question of what happens when an unstoppable force – Morant – meets an immovable object – the rim protection of Allen and Mobley.

On the other hand, the combination of Darius Garland and Donovan Mitchell for the Cavaliers are far more malleable with the way they create their offense.

Garland excels in 'floater range' from five-to-nine feet away from the hoop, sitting 15th in the league with 1.3 makes per game at an efficient 50 per cent, while Mitchell provides the long-range assault.

Mitchell is averaging 3.1 makes per game on deep threes (greater than 25 feet), which trails only the Golden State Warriors' Splash Brothers, Stephen Curry (3.8) and Klay Thompson (3.2).

It should be a mouthwatering clash between the league's best two defensive teams, who both have all their young stars healthy and ready to go as they look to strengthen their playoff positions.

PIVOTAL PERFORMERS 

Cleveland Cavaliers – Jarrett Allen

It is no secret that Morant is the driving force behind the Grizzlies' success, and for him to dominate games, he needs to control the paint.

Allen is the Cavaliers' primary rim protector and will be tasked with preventing Morant from producing more of his highlight-reel finishes, and if he can turn Morant into a jump-shooter for the night, Cleveland will consider that a massive win.

Memphis Grizzlies – Desmond Bane

Desmond Bane is the perfect counterbalance to Morant, providing the Grizzlies with a dynamic shooting threat who holds the defense's attention at all times.

Through three seasons, Bane owns a ridiculous career three-point percentage of 43.3. It is not just a strong number, it is the seventh-best career figure of all-time, and places him in the absolute top echelon of shooters in today's game.

If he can hit a couple early and force the Cavaliers' defense to divert some of their attention away from Morant, Bane could open up everything for the Grizzlies' offense.

KEY BATTLE – Can the Cavaliers figure out how to win on the road?

Heading into this contest, both the Grizzlies (19-3) and the Cavaliers (19-4) sit top-three in the NBA's best home records.

The Grizzlies will get the honour of hosting this time, leaving the Cavs as the underdogs as they try to figure out what is behind their disappointing 9-13 record away from home this campaign.

HEAD-TO-HEAD

This will be the first time this season these two teams meet, although the Grizzlies have won each of the past three matchups.

The Cavaliers defeated the Grizzlies once during Morant's rookie season in 2019, but the former Rookie of the Year has not lost to them since.

Denver Nuggets superstar Nikola Jokic took another step towards a third consecutive MVP after dominating the Portland Trail Blazers in a 122-113 victory on Tuesday.

Jokic was unstoppable offensively, finishing with 36 points on 13-of-14 shooting while adding 12 rebounds and 10 assists. 

In doing so, he became the first player in NBA history to record multiple 35-point triple-doubles while shooting at least 90 per cent from the field. Hall-of-Famer Wilt Chamberlain is the only other player with even one such game.

Jokic was supported well by Michael Porter Jr, who scored 23 points on nine-of-13 shooting, while Jamal Murray chipped in 17 points (six-of-15), seven assists, five rebounds and two steals.

For the Blazers, it was another spectacular showing from the franchise's all-time scoring leader as Damian Lillard had a game-high 44 points on 12-of-20 shooting with eight assists.

It continued a blistering run of form for Lillard, who is averaging a league-leading 39 points per game across his past six outings, although Portland have only been able to convert his stellar play into two wins from six.

With the victory, the Nuggets are now alone atop the Western Conference with a record of 31-13, which the Memphis Grizzlies can tie if they can secure their 11th consecutive win when they face the Cleveland Cavaliers on Wednesday.

Holiday delivers for the Giannis-less Bucks

Jrue Holiday has set a new season-high points total in back-to-back games after putting up 37 in the Milwaukee Bucks' 130-122 triumph at home against the Toronto Raptors.

Holiday scored a season-high 35 on Monday against the Indiana Pacers in the first leg of the Bucks' back-to-back, and he followed it up with 37 against the Raptors.

He shot 16-of-26 from the field while adding seven assists, six rebounds, two steals and a block, and Fred VanVleet was just as good for Toronto.

VanVleet tied his season-high by scoring 39 points on 15-of-28 shooting, with nine rebounds and seven assists.

The Bucks are now 29-16 and occupy the second seed in the Eastern Conference.

Embiid bullies the Clippers

Joel Embiid was too big and too strong on his way to a game-high 41 points in the Philadelphia 76ers' 120-110 road win against the Los Angeles Clippers.

Embiid shot 12-of-22 from the field and 15-of-18 from the free throw line while adding nine rebounds, three assists and two blocks in a comprehensive performance.

Tobias Harris was sharp in a supporting role, snatching five steals in the first half while scoring 20 points on efficient eight-of-12 shooting.

For the Clippers, Kawhi Leonard made it five consecutive games with at least 24 points and a steal as he begins to recapture his All-NBA form following a string of injuries.

World number one and tournament favourite Iga Swiatek feels second-round opponent Camila Osorio did not do much wrong despite going down 6-2 6-3 on Wednesday.

Swiatek is seeking her fourth career grand slam singles title, and the 21-year-old is yet to drop a set through two rounds at the Australian Open.

She was nearly flawless in her service game against Osorio, landing 80 per cent of her first serves fair while also committing zero double faults, and she was just as impressive when on the return.

Osorio was able to win just 31 per cent of her service points in the opening set (eight-of-26), and for the match she only held serve on two occasions from eight attempts.

Despite Swiatek's clear advantage in both phases, Osorio managed to break her serve three times, and the Polish superstar said she was made to earn every point.

"It was much tougher than this score says – it was really intense physically and Camila was really running to every ball," she said. "She didn’t give up. She didn’t give me many points for free. 

"So I needed to really work for each of them and it was tough, but I’m happy that I was proactive and trying to just play a little bit to put pressure [on her]. I’m pretty happy that I won and I can play next round."

Swiatek also shared a story about when the rain started pouring on Tuesday night in the midst of her walk, urging spectators in jest to come to her aid if a similar situation arises in the future.

"In Melbourne it’s usually sunny, except today and yesterday," she said. "So I need to change my plans. 

"Yesterday I actually went for a walk at 7[pm] and it started raining, and I was just hiding under the tree, waiting for like 30 minutes.

"So if there’s anybody who’s going to see me tonight walking in the rain, please save me, give me an umbrella or something."

Swiatek's march to what would be her first Australian Open final continues when she takes on the winner between Cristina Bucsa and Bianca Andreescu in the third round.

Kyrie Irving missed the Brooklyn Nets' 106-98 loss to the San Antonio Spurs on Tuesday due to tightness in his right calf.

Irving, who has now played in 32 of the Nets' 43 games this season, is averaging 25.6 points, 4.8 rebounds and 4.8 assists per game, and he has already eclipsed the 29 games he managed in the 2021-22 campaign.

The Nets were already without superstar Kevin Durant due to his knee injury, and were left even more shorthanded when Irving was withdrawn in the hours before tip-off against the Spurs.

In his absence, Brooklyn suffered their third loss in a row as no Nets players were able to reach 20 points.

Ben Simmons collected a triple-double with 10 points, 11 assists, 10 rebounds, four steals and two blocks, while T.J. Warren led the team in scoring with 19 points off the bench.

Meanwhile, 23-year-old Nets center Nic Claxton became the youngest player since 22-year-old Rudy Gobert in 2015 to block at least three shots in nine consecutive games.

In comments before the game, head coach Jacque Vaughn called the injury "day to day".

"[Irving] just reported a little tightness," Vaughn said. "It's essentially just day to day. We'll check on him [Wednesday], and hopefully this is short-term."

The Nets are hopeful Irving will be able to return when they travel to take on the Phoenix Suns on Thursday.

World number one Iga Swiatek had no problem dealing with Camila Osorio during Wednesday's second round, advancing with a 6-2 6-3 victory.

Swiatek, 21, is seeking her fourth grand slam title and her first at the Australian Open, having already won the French Open twice before claiming her first US Open crown this past season.

Against Osorio, it was Swiatek's ability to consistently return that was the difference, holding the Colombian to just a 31 per cent success rate on her service points in the opening set (eight-of-26).

It resulted in a lightning-quick start for the Polish superstar, winning the first four games of the match, and despite giving back a couple breaks of serve, Swiatek did not allow Osorio to hold serve a single time in the opening frame.

Osorio was able to finally hold serve to begin the second set, before Swiatek again rattled off four consecutive games to collect a double-break and a winning lead.

In a remarkably clean performance from the tournament favourite, Swiatek landed 80 per cent of her first serves fair while committing no double faults, and both players finished with more winners than unforced errors.

With the victory, Swiatek will now face the winner between Cristina Bucsa and Bianca Andreescu in the third round.

Data Slam: Swiatek in legendary company

Swiatek has now won 53 of her first 65 grand slam matches – the sixth-best total through 65 attempts in the Open Era.

She trails only Margaret Court (61), Monica Seles (60), Chris Evert (57), Martina Hingis (56), Billie Jean King (56) and Tracy Austin (54).

Serie A leaders Napoli lost to basement side Cremonese to exit the Coppa Italia and be left with "so much disappointment".

This looks like being a dream season for the Partenopei, who have established a nine-point advantage at the top of the table as they bid for a first Scudetto since 1990.

Luciano Spalletti's side are also through in the Champions League after an impressive group stage, but there will be no improbable treble.

That is because a seemingly straightforward Coppa tie against 10-man Cremonese saw Napoli eliminated on Tuesday.

Cremonese have not won a single game in Serie A all season but reached the round of 16 for just the third time in their history thanks to a penalty shoot-out success following a 2-2 draw.

Napoli, whose line-up showed 10 changes from their stunning 5-1 defeat of Juventus on Friday, looked to be heading through after Juan Jesus and Giovanni Simeone scored in quick succession in the first half to cancel out Charles Pickel's opener.

But Felix Afena-Gyan pulled Cremonese level three minutes from time, and the strugglers survived extra time even after Leonardo Sernicola was sent off.

In a shoot-out, only Napoli substitute Stanislav Lobotka missed – a costly error for a team who had also introduced Victor Osimhen from the bench by that point.

"We are sorry," coach Spalletti told Mediaset. "There is so much disappointment.

"We always have to go through the management of the game, of the ball, and we have not been as good as we usually are.

"But then the game was in complete safety because they, apart from a few balls to the attackers, could not do much. We conceded goals in a situation where we lost two balls that were going out.

"Then we scored two goals and wasted several chances, but unfortunately that's how it works. When you question a game that was under management then it becomes complicated."

Ran Carthon has landed his first general manager job with the Tennessee Titans.

News of Carthon's hire in Tennessee was reported by NFL Network on Tuesday.

The 41-year-old had been the San Francisco 49ers' director of player personnel, having previously held a similar role with the Los Angeles Rams.

He had also been a scout with the Atlanta Falcons.

Carthon is replacing Jon Robinson, who was fired in early December.

Titans owner Amy Adams Strunk said in a statement explaining that decision: "I am proud of what we have accomplished in my eight seasons of ownership, but I believe there is more to be done and higher aspirations to be met."

Robinson had been the GM since 2016, with the team reaching the playoffs in four of his seven seasons.

Jurgen Klopp welcomed the return of the "passion" Liverpool have been lacking as a much-changed side beat Wolves 1-0 in an FA Cup third-round replay at Molineux.

Reds manager Klopp made eight changes to his starting line-up following an alarming 3-0 Premier League defeat at Brighton and Hove Albion on Saturday.

Harvey Elliott was among the players who came into the side and the teenager proved to be the match-winner, scoring the only goal with a stunning long-range strike in the 13th minute.

A first win in four matches gives the holders an opportunity to exact revenge on Brighton in a fourth-round tie at the Amex Stadium.

It was anything but a classic all-Premier League tie after a 2-2 draw at Anfield ensured the two sides had to do battle again, but Klopp was not concerned about entertainment value. 

He told BBC Sport: "It feels like ages ago we had a feeling of winning and playing well. We had to fight hard at the end, which we controlled for long periods. It is great and the reaction we wanted to see."

Klopp vowed he would not quit after the defeat to Brighton and urged his players to go "back to basics".

The German was impressed with the way they responded to a painful loss last weekend.

 "From the passion we showed, yes," he said. "It is my job to help the boys and find the formation where they feel good from the start. Stefan Bajcetic and the whole midfield was really compact, so it was difficult for Wolves to find the key players like Joao Moutinho. I liked the game a lot."

Elliott was named man of the match, but Klopp felt several of his players were candidates for the award.

He added: "It was good from Harvey Elliott, especially after an early knock to the ankle. He fought through, and the goal was exceptional.

"I had a few man of the match performances today. We played a really good first half, had good periods in the second, and in the end it was just passion to block the shots. A cup game, great."

Gregor Townsend knows the upcoming Six Nations could be his last in charge of Scotland as he revealed he has been contacted by France.

Townsend named his Six Nations squad on Tuesday with four uncapped players included in the 40-man selection.

That includes Ben Healy, who has qualified to play for Scotland through his mother, as well as Ruaridh McConnochie, who has previously played for England.

The 49-year-old has been in charge of Scotland since 2017, but his contract is up after this year's Rugby World Cup in France, which starts in September.

Townsend told reporters he would like clarity on his situation before the tournament begins but knows he might "have to wait and see".

"No discussions have been had, and I don't see them taking place until after the Six Nations," he added.

When asked if this could be his last Six Nations as Scotland coach, Townsend replied: "I'm not contracted beyond this year, so of course."

Meanwhile, Townsend confirmed reports he had been contacted over the possibility of joining France's set-up in the wake of the World Cup. 

"I did get a contact from France," he said. "It was just an initial enquiry and there was nothing further from that because we obviously play France in the Six Nations, so I didn't want to talk any further with them about that."

Scotland take on England at Twickenham in their opening Six Nations match on February 4.

Scotland's Six Nations squad
