The Los Angeles Lakers survived to outlast the high-flying Miami Heat 120-117 in overtime as Russell Westbrook led the way in the NBA.

Westbrook posted a triple-double of 25 points, 12 rebounds and 14 assists, while team-mate Anthony Davis scored 24 points and collected 13 rebounds to fuel the Lakers (7-5) in the continued absence of LeBron James on Wednesday.

The Lakers had trailed 102-93 with less than seven minutes remaining in the fourth quarter before rallying to force OT.

Malik Monk, who had a team-high 27 points, scored five of the Lakers' eight points in overtime to secure victory at Staples Center.

Double-doubles from Bam Adebayo (28 points, 10 rebounds, six steals and four assists) and Kyle Lowry (18 points and 11 assists) were not enough for the Heat (7-4), who lost Jimmy Butler to injury.

Durant reaches MJ levels, Wiggins' Warriors win 10th game

The Brooklyn Nets (8-4) crushed the Orlando Magic (3-9) 123-90 behind Kevin Durant's 30 points on 11-of-12 shooting. In his 12 games this season, Durant has been averaging 29.5 points, 8.5 rebounds and 5.0 assists per game, while shooting 58.5 per cent from the field and 82.9 per cent from the free-throw line. According to Stats Perform, the last player to reach all those numbers over any 12-game span was Hall of Famer Michael Jordan in 1988. James Harden had his 59th career triple-double of 17 points, 11 rebounds and 11 assists.

Andrew Wiggins flexed his muscles against former team the Minnesota Timberwolves, putting up 35 points to inspire the NBA-leading Golden State Warriors (10-1) to a 123-110 victory. Anthony Edwards' career-high 48 points were not enough for the Timberwolves (3-7).

Defending champions the Milwaukee Bucks (6-6) blew a 24-point lead before overcoming the New York Knicks (7-5) 112-100. Giannis Antetokounmpo (15 points, 15 rebounds and eight assists) fell short of a triple-double.

Reeling Pelicans lose eighth straight

The New Orleans Pelicans' season went from bad to worse on Wednesday following a 108-100 loss to the Oklahoma City Thunder (4-6). New Orleans – without star pair Zion Williamson and Brandon Ingram – have lost eight games in a row to be a league-worst 1-11.

Karolina Pliskova continued her dominance against Garbine Muguruza with an epic three-set win at the WTA Finals.

Pliskova outlasted former world number one Muguruza 4-6 6-2 7-6 (8-6) as the year-ending WTA Finals got underway in Guadalajara on Wednesday.

The first WTA Finals hosted in Latin America, third seed Pliskova prevailed in a third-set tie-break for her ninth victory over two-time grand slam champion Muguruza – her best professional record against an opponent on Tour.

After a slow start, sixth seed and Spanish star Muguruza finished strongly to claim the opening set of the Group Teotihuacan contest under the Guadalajara lights midweek.

Pliskova – the most experienced player in this year's field with her fourth consecutive Finals appearance – raced out to a 3-0 lead in the second set and it was an advantage she never relinquished.

The pair went toe-to-toe in the final set as a tie-break loomed after Muguruza saved two match points in the 10th game.

Pliskova, however, was not to be denied as Muguruza lost a third-set tie-break on hard courts for the first time since January 2014.

Max Verstappen is bidding to boost his advantage on a race weekend at the Sao Paulo Grand Prix that could prove crucial in helping him close in on a first Formula One world title.

Consecutive victories in the United States and Mexico have seen Verstappen grow his lead over seven-time champion Lewis Hamilton to 19 points with just four races remaining.

The result this week at Interlagos, where 29 points are up for grabs as the third and final sprint race of the season takes place on Saturday ahead of the main event on Sunday, could therefore have a seismic impact.

A third straight win would equal the best run in Verstappen's impressive young career but most importantly put him in prime position for the biggest prize of all, which would deny Hamilton the chance to surpass Michael Schumacher and claim an all-time record eighth title.

Red Bull were clearly the faster car in Mexico as previous form proved an accurate guide to that race. They have also fared well of late in Brazil, with the Dutchman winning the last time a race was held at Interlagos in 2019 after a second-placed finish the year before.

The 19-point lead is the second-biggest gap between Verstappen and Hamilton this season. Only in Austria was it larger (32) in a year when it has been tough to separate the pair.

Red Bull have also closed to within one point of Mercedes in the constructors' championship, the smallest gap between two teams at this stage of any season in the 21st century.

Christian Horner's team have had both drivers on the podium in three straight races, their best run in the hybrid era, and repeating the feat here would put them closer to claiming both crowns, ending a historic spell of Mercedes dominance.

However, Hamilton will have plenty to say about that – he has 17 career wins in the Americas (seven in Canada, six in the USA, two in Brazil and two in Mexico). One more would give him the record in that category which he currently shares with Schumacher.

LAST TIME OUT

Verstappen roared to victory in Mexico, moving from third on the grid to the lead by the first corner.

Valtteri Bottas – who had started in pole position – dropped down to last after being hit from behind in a frantic start and could not recover to finish in the points, though he did claim the fastest lap to deny Verstappen an additional point.

Verstappen was rarely troubled after his fine start, claiming a 19th career win and ninth of the season by more than 16 seconds ahead of Hamilton, who held on for second in a battle with home favourite Sergio Perez, a result Mercedes team boss Toto Wolff said should be seen like a win given the pace difference between the two cars.

Pierre Gasly took fourth to make it three drivers connected to Red Bull in the first four places, with the Ferraris of Charles Leclerc and Carlos Sainz rounding out the top six.

WHAT TO EXPECT IN BRAZIL

While the gap is expected to be closer at Interlagos than it was in Mexico City, Verstappen goes into the race weekend as favourite given Red Bull's strong momentum.

However, he has not fared well in the two previous race weekends when the sprint format took place and is yet to claim a point in the main race under those circumstances.

He did claim pole – and five valuable championship points – when he won the sprint at Silverstone and came second at Monza to Bottas, who served a penalty, only to retire from each race after collisions with Hamilton.

Hamilton will be up for a scrap again as he desperately bids to remain in contention and Wolff insisted this week it is all still to play for, given the Briton impressively limited the damage with second place in Mexico, one of Mercedes' worst tracks.

Wolff added: "We are going to Brazil – that was not much better for us than Mexico in the past but at least we believe that we can have a solid car there, more close to Red Bull than what we had.

"None of us is ever going to have the mentality of this is going away from us. There is four races to go, four wins to take, four DNFs to suffer, and we will just continue fighting.

"We know that we have a great team. When you look at the mathematical probability then I would rather be 19 points ahead than behind, but it is what it is."

TOP FIVE OPTA FACTS

Front row vital – Fifteen of the past 16 winners in Brazil have come from the first row of the grid (eight from pole). Kimi Raikkonen was the last winner to come from further back, doing so in 2007 when he emerged triumphant from third to clinch the drivers' title.

Unwelcome records – If he finishes second, Bottas will surpass Rubens Barrichello as the driver who has the most runner-up finishes in F1 (30) without being a world champion. He is already the driver who has the most career poles (19) without winning a world title.

Fast Fernando – Alpine star Alonso is the driver who has gained the most positions across both of the sprint races held so far in 2021 (six).

Lando luck – Since he retired in Hungary, Lando Norris – who turns 22 this weekend – has finished in the top five just once in seven F1 races (when he came second in Monza). He had been in the top five in nine of the previous 10 events before this poor run.

Fond memories – Eleven years ago on race day, Sebastian Vettel (Aston Martin) became the youngest driver to win the F1 world championship in Abu Dhabi at 23 years, four months and 11 days old.

Damian Lillard claims officiating in the NBA this season has been "unacceptable", as he did not expect to be impacted by the league's foul rule change.

A new interpretation of the foul rule in 2021-22 has seen a "change in the officiating of overt, abrupt or abnormal non-basketball moves by offensive players with the ball in an effort to draw fouls", essentially meaning fewer trips to the foul line for certain players.

Portland Trail Blazers star Lillard had attempted 484 free throws last year, the fifth-most in the NBA.

But that figure has dropped from 7.2 per game all the way down to 3.2 following the officiating changes, a huge factor in Lillard's points output decreasing from an elite 28.8 to 19.3.

Only in his rookie season has the point guard scored fewer points per game, while he has never averaged fewer free throw attempts.

Given Lillard scored 23.1 per cent of the Blazers' points in 2020-21, with only Stephen Curry on the Golden State Warriors contributing a greater share (24.6 per cent), this dip has had a significant knock-on effect.

Portland are 5-6 this year and one of only three teams still winless on the road, with their latest loss coming on Tuesday at the Los Angeles Clippers.

The Blazers had snapped a seven-game losing streak against the Clippers in the teams' previous meeting but went down 117-109 at Staples Center, where Lillard was furious with the officials, restricted to only one free throw attempt.

He has visited the foul line just three times in the past three games and let rip during his post-game media duties.

"I feel like the way the game is being officiated is unacceptable," Lillard said.

"I don't want to go too deep into it so they make a big deal out of it, but the explanations, the s*** that's getting missed, I mean, come on...

"I'm not that type of player – I felt like coming in, the rule change wouldn't affect me, because I don't do the trick the referees, I don't do the trick plays. It's just unacceptable, man.

"Then the explanations and the remarks in return when you're telling them is just like... I don't really have anything else to say about it."

For all Lillard's complaints, his shooting performance has also been down this year, averaging 36.5 per cent from the field, 25.5 per cent from three-point range and 85.7 from the foul line; he was 45.1, 39.1 and 92.8 last season.

These numbers were not helped by a hopeless performance against the Indiana Pacers last week, when he was two-of-13 from the field for a mere four points in 38 minutes.

Only once previously in his career had Lillard scored so few points while playing more minutes (four in 40 versus the Orlando Magic in 2013).

But he had a year-high 27 against the Clippers and added: "I'm feeling better each game. I still feel like I'm not completely rolling, but I'm feeling better every game."

The 2021 WTA Finals look set to be a fitting end to a fascinating season on the Tour.

The 50th year-ending championships, which will take place in Guadalajara instead of Shenzhen due to coronavirus restrictions, will see eight of the top-10 ranked players come together in two round-robin groups, with four semi-final places up for grabs.

Six of the eight competitors will make their debuts at the event, while only two grand slam finalists from this year – and just one champion – will be present. With world number one Ash Barty withdrawing because of concerns around possible quarantine issues, it really does feel like an open draw.

Stats Perform looks at the eight Finalists and the key data you need to know before the action gets underway...

Group Chichen Itza

Aryna Sabalenka (1)

World number two Sabalenka is the top-ranked competitor in Guadalajara, with 44 match wins this year and titles in Abu Dhabi and Madrid, where she beat Barty.

The Belarusian boasts formidable weapons: Sabalenka has won 71.1 per cent of first-serve points and has an average of 8.4 forehand winners per match on the Tour this season, both of which are best figures among the eight Finalists.

She has only played two matches since losing to Leylah Fernandez in the US Open semi-finals, though, both of which were at last month's Kremlin Cup in Moscow.

Did you know? Since the start of 2018, Sabalenka has won the joint-most matches (three) in WTA Tour main draws after losing the first set 0-6. At the same time, she is 9-13 in three-set contests in 2021.

Maria Sakkari (4)

The nearly-woman of 2021, Sakkari has reached more semi-finals this year (seven) than anyone else on the WTA Tour, including at two of the four slams, but made it to just one final (in Ostrava, where she lost to Anett Kontaveit).

Still, this has been a historic year for the 26-year-old, who became the first Greek woman to reach a major semi-final, enter the top 10 and qualify for the season-ending championship.

Since the start of the US Open, Sakkari has lost only four of 14 matches, a run that includes the semi-final of the Kremlin Cup where she retired due to dizziness.

Did you know? Nobody has won more Tour-level matches against top-10 opponents this year than Sakkari (seven, level with Barty and Jessica Pegula). Before 2021, her record in such matches was 10-13.

Iga Swiatek (5)

Swiatek, the 2020 French Open champion, is the youngest competitor at these Finals at 20 years and 170 days old (as of the tournament's end). She is just the second player born this century to reach this event, after Bianca Andreescu in 2019.

Although unable to get beyond the quarter-finals of a major this year, Swiatek did win titles in Adelaide and Rome, where she inflicted a double bagel on Karolina Pliskova in the final.

Her success in Australia was her first on a hard court, a surface on which she won 19 of 28 matches this year.

Did you know? Swiatek has won 58 per cent (28 of 48) of her matches this season in straight sets, the highest ratio among the Finalists.

Paula Badosa (7)

A successful year for Badosa has been built on clay: she won a Tour-leading 17 matches on the dirt in 2021, reaching the French Open quarter-finals, the last four in Madrid and Charleston and winning the title in Belgrade.

This has been a breakthrough season for the 23-year-old across all surfaces, though, one that culminated in a record-breaking three-set win over Victoria Azarenka in the final at Indian Wells last month.

Badosa clinched that match after a third-set tie-break. She has won four deciding sets in that fashion this year, the most of anyone on the WTA Tour.

Did you know? Badosa has won seven matches (excluding the Olympics) after dropping the first set in 2021. Nobody else has as many come-from-behind victories among the Finalists.

Group Teotihuacan

Barbora Krejcikova (2)

The only major singles champion from 2021 at these Finals, Krejcikova has enjoyed a remarkable rise this year.

Along with success at Roland Garros, where she also triumphed in the doubles, the Czech won titles in Strasbourg and Prague; only world number one Barty (five) and Kontaveit (four) have won more this year.

Among the eight finalists, Krejcikova boasts the highest break-point conversion ratio (49.7 per cent, or 142/286) and break-point saved figure (66.4 per cent, or 150/226) for this season. She has become a clutch competitor and will be hard to stop in Mexico, both in the singles and the doubles.

Did you know? Krejcikova has won six matches against top-20 opponents in her career. All six of those wins were in 2021.

Karolina Pliskova (3)

Pliskova boasts impressive experience of the year-ending event: she is only the fourth player to qualify for five or more WTA Finals since the current format was introduced in 2003 (after Agnieszka Radwanska, Petra Kvitova and Azarenka).

Beaten in her three Tour finals this year, including Wimbledon, the 29-year-old will be desperate to go at least one better than her three consecutive semi-final appearances at this event.

Pliskova begins against Garbine Muguruza, a player she has beaten twice before at the season-ending tournament.

Did you know? Pliskova leads the Tour for aces this season with 364, hitting a year-best 21 in her round-of-16 match with Jelena Ostapenko in Stuttgart. It's the fourth time in the past six seasons Pliskova has been top of the aces standings.

Garbine Muguruza (6)

This is the first time since 2000 that two Spanish players have contested the Finals. Back then, it was Conchita Martinez and Arantxa Sanchez Vicario at Madison Square Garden in New York.

Muguruza, champion in Dubai and Chicago this year, has won more matches on hard courts (34) than anyone else in 2021 aside from Kontaveit. She also boasts the best average for successful net approaches this year (3.0) among the Finalists, which will make her a challenging obstacle in what will be her first Finals since 2017.

The former world number won made a career-high four Tour finals this year and won more than one trophy in a season for just the second time, sending her back into the top 10 for the first time since 2018. 

Did you know? Muguruza boasts a 10-1 record in WTA tournaments in Mexico, winning back-to-back titles in Monterrey in 2018 and 2019.

Anett Kontaveit (8)

With a Tour-leading 37 hard-court wins this year and on a formidable run of form, Kontaveit could spring a surprise at her first Finals.

After losing her fifth match in a row to Ons Jabeur on August 17, the Estonian went on a run of 26 wins from 28 matches, lifted four titles and broke into the top 10 for the first time. It was Jabeur she edged out for a place at this tournament after she won her fourth title of the year at Cluj-Napoca.

Along with Barty, Kontaveit is the only player to reach six Tour-level finals this year, while nobody at the season-ending tournament has won more titles (four).

Did you know? Kontaveit has hit the most backhand winners (293) on hard courts on the WTA Tour in 2021, averaging nearly six per match.

Doc Rivers is unclear about the severity of Seth Curry's foot injury as the Philadelphia 76ers' availability concerns got worse with the guard withdrawn prior to Tuesday's 118-109 loss to the Milwaukee Bucks.

The 76ers went into the game leading the Eastern Conference at 8-3 despite being without Joel Embiid, Matisse Thybulle, Isaiah Joe and Tobias Harris due to COVID-19, with Ben Simmons also still unavailable.

Curry was pulled out of the 76ers side for the game shortly before tipoff with a left foot contusion.

"I don’t know," Rivers told reporters about Curry's injury after the game. "I literally thought he was gonna play and then late, you could hear the language, it didn’t sound like he was gonna play.

"We start adjusting pretty quickly after that. I’m not even sure what it is. I think it’s his toe, but I’m not sure."

Guard Tyrese Maxey scored 31 points, with five rebounds and four assists, while center Andre Drummond had 17 points along with 20 rebounds, but the 76ers missed their stars.

Rivers had indicated pre-game that Harris may be the closest to returning of the quartet who had entered the league's health and safety protocol.

"All the other guys are still where they're at. I would say just talking to Tobias, he's the one guy who'll be back sooner than later," Rivers said.

Rivers was impressed that the decimated 76ers, who also lost to the New York Knicks on Monday, were in the hunt against the reigning champions before a 27-16 fourth quarter.

"We gave ourselves a chance to win the game in both and there’s something to be taken from that so we do learn a lot," Rivers said. "But we didn’t win the games. That’s a fact.

"We had chances. It’s an opportunity to grow, an opportunity to get better, I’m not down about the loss. You either do one of two things in a competition. You either win the game or you lose the game. Period.”

Two-time NBA MVP Giannis Antetokounmpo says the Milwaukee Bucks will reap the benefits of rotating their roster amid injuries later in the championship race.

The reigning champions overcame the under-manned Eastern Conference leaders the Philadelphia 76ers 118-109 on Tuesday, snapping a run of five losses in six games.

Antetokounmpo starred with 31 points, 16 rebounds, four assists and two blocks, but unheralded Grayson Allen and Bobby Portis impressed in the absence of small forward Khris Middleton (COVID-19) and center Brook Lopez (back).

Allen hit five three-pointers to finish with 25 points, while starting center Portis had 19 points and 10 rebounds across 35 minutes on court. Semi Ojeleye added 11 points and eight rebounds off the bench.

"Obviously you always want to win, you play to win," Antetokounmpo said during his post-game news conference. "Grayson and Semi today were really good.

"Semi was shooting his open shots, he was being aggressive, diving for the ball. That's good. We're going to need that.

"We need these guys feeling comfortable playing with me and Jrue [Holiday]. We're going to need everybody to win a championship and play down the stretch in May and June."

Allen, who joined the Bucks from the Memphis Grizzlies in the off-season, went eight-for-13 from the field, including shooting at 56 per cent from beyond the arc.

"Grayson did a good job getting to the right spots," Antetokounmpo said.

The Bucks finished strong with a 27-16 fourth quarter to get over the 76ers, who were without Joel Embiid. The win improves Milwaukee's record to 5-6 on the season.

"It's always good to get a win," the Greek forward said. "Sometimes it's pretty, sometimes it's ugly, but a win is a win. We're trying to build some momentum here.

"With a stop or a block or a play or a pass, just do whatever it takes to get a win. That's what my team needs me to do. That's why I showed a bit of emotion... I just wanted us to get a win."

Holiday missed his three attempts from three-point range and shot four-for-14 from the field to finish with eight points in his third game back from an ankle injury.

Bucks head coach Mike Budenholzer said: "I thought he had some big plays defensively. His effort on the boards, he can put a body on a guy like Drummond, so Giannis and Bobby can clean stuff up. Jrue is working his way and really getting better."

Clayton Kershaw will "always have a spot" on the Dodgers if he wants to remain in Los Angeles next season, says team president of baseball operations Andrew Friedman. 

Drafted out of high school by the Dodgers in 2006, Kershaw has spent his entire career with the franchise but is a free agent this offseason after the team declined to issue him a qualifying offer for 2022. 

That decision was not a surprise, as forearm problems caused Kershaw to miss more than two months during the regular season and the entire postseason. 

But Friedman told reporters on Tuesday that move should not be seen as a sign that the door is closed. 

"We've been very outspoken that we really want Kersh to come back, not only what he's meant to us looking back, but also what we think he will mean for us looking forward," Friedman said at the MLB general managers' meetings in California, via ESPN. 

"That being said - just like every free agent, but Kersh even a little bit more so - he has earned the right to be in this position and figure out what's best for him and his family.

"So there's like a personal and a professional tug of war for me. Professionally I really hope he's back, personally I want them to do what makes the most sense for their family, and we'll figure out what that means."

Kershaw wrapped up a three-year, $93million contract this season, and the Dallas-area native's hometown Texas Rangers are expected to make a strong push to sign him. 

The 33-year-old went 10-8 with a 3.55 ERA and 144 strikeouts in 121.2 innings this season, the ERA representing the second-worst of his career ahead of only a 4.26 as a rookie in 2008. 

Kershaw has a 185-84 career record with 2,670 strikeouts and a 2.49 ERA, winning three Cy Young Awards and eight All-Star selections along the way in addition to the 2014 National League MVP award. 

The Milwaukee Bucks picked up a much-needed victory against a depleted opponent on Tuesday, outlasting the Philadelphia 76ers 118-109. 

Giannis Antetokounmpo had 31 points and 16 rebounds for the reigning NBA champions, who had lost five of their previous six games. 

Milwaukee (5-6) caught the 76ers at the right time, with Joel Embiid and Tobias Harris among four players sidelined by COVID-19 protocols and Seth Curry nursing a left foot contusion. 

Despite those absences, Philadelphia (8-4) stayed in the game until the closing minutes, leading by as many as 13 in the second quarter and entering the fourth quarter up 93-91. 

Tyrese Maxey had 39 points and Embiid's replacement, Andre Drummond, contributed 17 points and 20 rebounds for the 76ers, who have dropped six straight games to the Bucks. 

George, Clippers keep Blazers winless on road

Paul George led a balanced Clippers attack with 24 points, nine rebounds and seven assists as Los Angeles defeated the Portland Trail Blazers 117-109. The loss kept Portland (5-6) winless in five road games this season, with two of those losses coming at Staples Center. 

Reggie Jackson added 23 points for the Clippers (6-4), while Nicolas Batum contributed 22 as he made six of eight shots from three-point range. Damian Lillard scored 27 to lead the Blazers. 

Cold-shooting Hawks fall to Jazz

The Atlanta Hawks made an impressive 51.4 percent of their three-point attempts (18 of 35) against the Utah Jazz, but connected on just 19 of 50 (38 per cent) from two-point range as they fell 110-98. 

The NBA has suspended Denver Nuggets star Nikola Jokic for one game for "forcefully shoving" the Miami Heat's Markieff Morris on Monday. 

Morris was fined $50,000 for a Flagrant 2 foul that precipitated the incident, which saw both players ejected from the game. The Nuggets went on to win 113-96.

Miami's Jimmy Butler also was fined $30,000 for "attempting to escalate the altercation" and refusing to submit to an interview with NBA security as it investigated the matter. 

Jokic reacted angrily when Morris came in with a hard foul at midcourt with 2:39 to play in the game, catching his opponent with a left elbow to the chest.

Last season's NBA MVP charged after Morris and responded with a right forearm shove to the back, sending the Heat player crashing heavily to the court.

Both teams' coaching staffs sprang from their benches to try and restore order along with the referees. 

Heat head coach Erik Spoelstra called it a "very dangerous, dirty play" by Jokic, who expressed regret following the game. 

"It's a stupid play. I feel bad. I am not supposed to react that way," Jokic told reporters. "... I just needed to protect myself. I felt bad. I am not supposed to react that way, but I need to protect myself."

Jokic will have to sit out Denver's game against the Indiana Pacers on Wednesday. 

Emma Raducanu has appointed Torben Beltz as her new coach almost seven weeks after parting company with Andrew Richardson.

The 18-year-old rose to international fame in September when she pulled off the incredible feat of clinching the US Open before ever even winning a single match on the WTA Tour.

Raducanu beat fellow teenager Leylah Fernandez to become the first qualifier in tennis history to win a grand slam and youngest winner of a women's major since 17-year-old Maria Sharapova took the Wimbledon title in 2004.

But she announced soon after that she and Richardson were no longer working together, with Raducanu continuing in the meantime without a coach as she scoured for someone with more WTA Tour experience.

Since the US Open, she has played just five matches and lost three of them, the latest coming on Tuesday as she suffered a 6-1 6-7 (0-7) 7-5 defeat to Wang Xinyu at the Linz Open, where Raducanu was the top seed.

But as she looks ahead to starting pre-season at the end of November, Raducanu will begin working with Beltz in the hope of building on her incredible breakthrough year.

The German was Angelique Kerber's coach during her US Open and Australian Open successes in 2016, and Raducanu is excited to get started.

Speaking after her defeat in Linz, Raducanu said: "You guys cracked it! It's obviously a great privilege to be working with such an experienced coach.

"I'm definitely very excited to work with him throughout the pre-season and into next year. I'm feeling excited about all the work that is to come.

"I think he brings a lot of experience. Obviously he's worked with Kerber, who's such a great player and has done extremely well, won three slams. I think that experience definitely helps with someone as inexperienced as me.

"He can help guide me through, which I feel really confident about, and also he's a really positive, cheerful guy who brings great energy to the team, so I think that's also important when you're travelling on the road for quite a long time on the tour."

Sebastian Korda produced an inspired turnaround from two sets down to defeat Hugo Gaston 3-4(2) 3-4(6) 4-0 4-3(3) 4-0 in his opening match at the Next Gen ATP Finals.

The American became only the second player in the history of this event to achieve the feat, after Borna Coric against Karen Khachanov in 2017.

Korda is the second seed in Milan this year following an impressive 2021 that saw him capture his first ATP title at the Emilia-Romagna Open, and reach the Miami Masters quarter-finals and Wimbledon fourth round.

The 21-year-old looked destined to begin Group B with a defeat after losing the opening two sets on tie-breaks, while he also saved match point at 3-2 down in the fourth.

Korda subsequently dominated the final set to complete a remarkable victory in just over two hours.

The world number 39 said: "[I] just stayed calm and kept thinking what I could do better. 

"I did play very well tactically in the first two sets, but I figured a couple of things out during the tie-break and I think that helped me for the rest of the match."

Meanwhile, top seed Carlos Alcaraz enjoyed a straight-sets victory over Holger Rune, prevailing 4-3(6) 4-2 4-0.

The Spanish teenager has also enjoyed a fruitful year on the ATP circuit, triumphing in Umag while beating world number three Stefanos Tsitsipas on the way to reaching the US Open quarter-finals.

And he made the perfect start in Group A; enjoying an 88 per cent first-serve success rate in a commanding win.

"I think it was a great match, both of us played really well," the world number 32 said.

"I am trying to go to the net and play aggressively in the important moments and stay calm. I am trying to do this every match."

Elsewhere, Brandon Nakashima – champion in Brest last month – made it 10 wins from 11 matches as he beat Juan Manuel Cerundolo 4-1 3-4(3) 4-1 4-0.

The 20-year-old, who became the youngest American to reach multiple tour-level finals since Andy Roddick earlier this year, was pegged back in the second set, but dominated the final two to seal victory in just over an hour-and-a-half.

However, there was no joy for home favourite Lorenzo Musetti, who was beaten in four sets by Sebastian Baez.

Though roared on by his home crowd, the world number 58 was unable to deliver in his opening match. Baez – a five-time Challenger Tour winner in 2021 – took full advantage to prevail 4-1 4-1 3-4(5) 4-3(5).

Montreal Canadiens goaltender Carey Price revealed he has received treatment for substance abuse.

The 34-year-old said he entered a residential facility last month after having reached "a very dark place" following years of "neglecting" his mental health.

Price had only just returned to the Canadiens following surgery on a knee injury during the off-season.

"Over the last few years I have let myself get to a very dark place and I didn't have the tools to cope with that struggle," he said via an Instagram post.

"Last month I made the decision to enter a residential treatment facility for substance use. Things had reached a point that I realized I needed to prioritize my health for both myself and for my family. Asking for help when you need it is what we encourage our kids to do, and it was what I needed to do.

"I am working through years of neglecting my own mental health which will take some time to repair; all I can do is take it day by day. With that comes some uncertainty with when I will return to play.

"I appreciate all of the overwhelming support and well wishes. I please ask that the media and our hockey community continue to respect our privacy at this time. Your support and respect of this so far has been a critical piece to my recovery."

Price, a seven-time NHL All-Star and Olympic gold medallist in 2014 with Canada, helped the Canadiens to their first Stanley Cup Finals appearance in 28 years last season, where they lost 4-1 to the Tampa Bay Lightning.

He posted a .901 save percentage last season, a figure he improved to .924 during the Canadiens' playoff run.

Speaking on Monday, coach Dominique Ducharme said: "I haven't met him yet. I need to see him. I'll see him tomorrow.

"He wants to come back and play, but there's other things to manage. We talked about the injury that he was coming back from, getting back in shape, and playing shape too. There's many steps to be taken, but he wants to play. He wants to be part of our group. He wants to help out."
