Belinda Bencic fought back to beat Angelique Kerber in a blockbuster showdown and help Switzerland eliminate Germany on day two of the Billie Jean King Cup in Prague.

Germany lost to hosts Czech Republic on the opening day and were brushed aside 3-0 by Switzerland on Tuesday, with world number nine Kerber losing 5-7 6-2 6-2 to Bencic.

Kerber was carrying an injury and was outlasted by the Olympic gold medallist, with that triumph coming after Viktorija Golubic defeated Andrea Petkovic 6-4 7-5.

Golubic and Jil Teichmann added further gloss to the scoreline by overcoming Anna-Lena Friedsam and Nastasja Mariana Schunk in the doubles.

Switzerland will now meet the Czech Republic in a winners-takes-all contest to determine who finishes top of Group D.

The upset of the day came in Group B as Australia beat Belgium 2-1, with Daria Gavrilova kicking things off by beating Greet Minnen 6-4 1-6 6-4.

Storm Sanders then battled back to beat Elise Mertens 4-6 7-6 (7-5) 6-0, rendering Mertens and Minnen's doubles win nothing more than a consolation. 

In Group A, Russia cruised to a 3-0 win over Canada.

Daria Kasatkina beat Carol Zhao 6-3 6-1 and Anastasia Pavlyuchenkova was too strong for Rebecca Marino as she prevailed in three sets.

Slovakia top Group C, meanwhile, after beating the United States 2-1. Shelby Rogers fell 6-4 6-4 to Viktoria Kuzmova before Danielle Collins levelled with a 6-3 6-2 win against Anna Karolina Schmiedlova.

That set up a decider in the doubles, which went the distance as the Slovakian pair of Kuzmova and Tereza Mihalikova prevailed 6-2 6-7 (5-7) 12-10 in a thriller with Caroline Dolehide and CoCo Vandeweghe.

Novak Djokovic recovered from a second-set blip to emerge victorious 6-2 4-6 6-3 in his first match since the US Open at the Paris Masters.

Victory in Paris would see Djokovic – competing for the first time since September's loss to Daniil Medvedev in the Flushing Meadows final – clinch the year-end number one ranking for a record seventh time.

Djokovic looked to be on course for a routine victory to start his campaign after comfortably taking the first set against Marton Fucsovics in their second-round contest on Tuesday.

However, the top seed's Hungarian opponent fought back to force a decider, hitting 13 winners to seven unforced errors in the second set.

But Djokovic – a record five-time Paris Masters champion – ensured a remarkable turnaround was not forthcoming, breaking Fucsovics twice in the third and, after letting one match point slip, clinching his second to secure victory.

Felix fights back

Ranked 12th in the ATP Race to Turin, Felix Auger-Aliassime needs to lift the trophy in Paris and hope Casper Ruud and Jannik Sinner do not reach the latter stages to make it to the ATP Finals.

Auger-Aliassime risked falling at the first hurdle on Tuesday as the ninth seed was forced to fight back to defeat Gianluca Mager 4-6 6-4 6-1.

"I had difficulty with my pace at the beginning of the match," said Auger-Aliassime. "I didn't hit enough first serves so I had a bit of pressure on my second serve.

"So I could have served better in the first set. I [had] a poor game at four-all and I got broken, but even before that there were moments at 30-all it was a bit hot and a bit tight. I think I relaxed. I found a better pace at the beginning of the second set, and it went even better as the match went forward."

He will next face Dominik Koepfer in the second round following the German's stunning win over Andy Murray on Monday.

Alcaraz sets up Sinner clash

Sinner will have an extremely testing second-round clash after Carlos Alcaraz came from behind to see off wild card Pierre Hugues-Herbert.

Alcaraz let slip a 4-2 lead in the first set to lose that on a tie-break but won six straight points in a second-set breaker before eventually battling to a 6-7 (4-7) 7-6 (7-2) 7-5 win in two hours, 53 minutes.

"It's not easy to play against a home player," Alcaraz said. "I think we played a good level and it was a great match, so I am happy to win. He has a great serve, so I had to return better and remain focus. I think that was the key. I am playing at a good level and I want to finish the year strong."

Diego Schwartzman – the 11th seed – needed three sets to see off John Millman, 15th seed Gael Monfils reversed a one-set deficit against Miomir Kecmanovic and 16th seed Grigor Dimitrov survived a three-setter with Richard Gasquet.

But one seed did fall on Tuesday, Roberto Bautista Agut (14) edged by James Duckworth in three sets.

The new NBA season is two weeks in and narratives are already forming.

The Golden State Warriors are back, the Chicago Bulls' rebuild was a success, and several top teams – including defending champions the Milwaukee Bucks – are toiling.

Those themes may not hold for the entire regular season, but we have now seen enough to recognise some patterns – and the same is true on an individual level.

Which players have made flying starts to this campaign, and which are yet to find their feet? Stats Perform takes a look with the first 2021-22 edition of NBA Heat Check.

RUNNING HOT...

Miles Bridges

The Charlotte Hornets were already a fun watch last year thanks to LaMelo Ball, but the second-year point guard has help in 2021-22. Bridges has been one of the key men in lifting the Hornets to an exciting 5-3 start.

Playing alongside Ball, Gordon Hayward and surprise 2020-21 star Terry Rozier, Bridges leads Charlotte in scoring with 23.1 points per game. Now in year four, his previous best had seen 13.0 in his sophomore season.

Bridges' shooting from the field (47.2 per cent) and from three-point range (34.4 per cent) is actually down on last year, while he is only marginally more accurate from the foul line (88.2 per cent).

But the forward is thriving on having been given increased responsibility this season. He is back to being a regular starter, up to 35.5 minutes per game from 29.3, and attempting almost twice as many shots. Through Monday's games, only seven players in the NBA had attempted more shots from three (61).

With assists (3.4), rebounds (7.9), steals (1.8) and blocks (0.9) also on the rise, the Hornets could have a major asset if Bridges maintains these standards.

Ja Morant

If Bridges' development has represented a major shock, Morant's has not. The Memphis Grizzlies sensation was the Rookie of the Year two seasons ago and dumped the Warriors out in the play-in round last year.

Still, Morant's performances have been mightily impressive. His 28.3 points per game trail only Stephen Curry and Paul George. Having played more games than both, his 198 total points lead the league. Morant also tops the charts for field goals made (75).

After a 2-0 start, Morant had 40 in a losing effort against the Los Angeles Lakers and soon added 30 against the Warriors to return the Grizzlies to winning ways.

The 22-year-old is certainly not the finished article – only Russell Westbrook has had more turnovers than his 34 and a plus/minus of -6.1 suggests his scoring is not making up for shortcomings in other areas – but the rate of improvement indicates Memphis will be rewarded soon enough for sticking by their man.

Harrison Barnes

Barnes has seen what elite looks like, having been drafted by the Warriors in 2012 and started every game across the regular season and playoffs when they won the title three years later.

But Barnes was merely the fourth or fifth scoring option on that team and, through moves to the Dallas Mavericks and then the Sacramento Kings, has taken time to establish himself as a leading man.

This could well be the year, though. Barnes is the Kings' top scorer with 23.3 points per game, boosted by a career-high 36 against the Portland Trail Blazers on opening night.

Perhaps unsurprisingly, the forward's scoring output has fallen with each passing performance since that stunning display, but he is bringing more to Sacramento than just scoring. Last year's 6.6 assists were a career high, only to be topped by a staggering 10.3 this time.

Although Barnes' Kings team-mates suggested after the Portland game they were always confident he could produce such displays, his progress at 29 has come as a surprise to everyone else.

GOING COLD...

Damian Lillard

Numerous players have explained away their below-par outputs by complaining about the NBA's new interpretation of the foul rule this season – 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 stars.

Trae Young, one of those prominently affected, named Lillard as another who was suffering more than usual.

Lillard is attempting only 3.9 free throws per game this year, in line with his career-low rookie year. His 18.6 points are below 19.0 he offered the Blazers in 2012-13. He had 28.8 last season.

But those foul calls are not Lillard's only issue, with his shooting from the field also hugely underwhelming through seven games.

The point guard is making only 34.9 per cent from the field and, having previously scored 4.1 three-point attempts per game, 23.1 per cent from beyond the arc. Those are also career lows and sources of major concern for Portland.

Dwight Howard

The Lakers made significant changes to their roster in the offseason and a number of the new recruits have not yet hit their stride.

It figures that Westbrook, now the third man in LA, should have seen his points (18.3), assists (8.7) and rebounds (8.7) take a hit along with his usage rate (28.5 per cent) after averaging a triple-double on the Washington Wizards, but Howard's slow early-season form was less predictable.

The three-time Defensive Player of the Year played a key bench role in the Lakers' title success in 2019-20, even starting seven playoff games, before joining the Philadelphia 76ers for a season.

Back at Staples Center, Howard is proving far less effective to this point. Both his points (4.3) and, most concerningly, rebounds (4.0) have reached career lows. His minutes are down from 17.3 last year to 15.2 this, but his averages per 48 only further display a decrease in performance – 23.3 rebounds becoming 12.7.

With Howard also involved in an altercation with Anthony Davis during a defeat to the Phoenix Suns, it is fair to say his Lakers return has not so far gone entirely to plan.

Dominic Thiem has confirmed he has been given a coronavirus vaccine and will return to action in Abu Dhabi next month with the objective of playing in the 2022 Australian Open.

The 2020 US Open champion has been out of action since suffering a wrist injury at the Mallorca Championships in June.

Thiem on Tuesday revealed he has made good progress with his recovery and will play in the World Tennis Championship, an exhibition event that will be staged from December 16-18.

The 28-year-old had stated he wanted to wait for a Novavax jab, but was urged by Austrian minister for Social Affairs, Health, Care and Consumer Protection Wolfgang Muckstein to take an alternative vaccine as his preferred choice would not be available until next year.

Thiem says he has now been vaccinated and is relishing getting back on court as he eyes a grand slam return in Melbourne in January.

"I am very happy to announce that my recovery is going well. The MRI I did today showed that my wrist injury has improved significantly," Thiem tweeted on Tuesday.

"A couple of weeks ago I started playing with soft balls and was able to switch to normal tennis balls during yesterday's practice session. My team and I strongly believe that I'll be ready to make my comeback later this year.

"I'll be returning to competition in December and will be playing the MWTC 2021 in Abu Dhabi – with the objective to return to the Tour for the 2022 Australian Open.

"Needless to say that the vaccine is needed to play both events, and in my case I have already been vaccinated. I saw recently some news about this and I had to make it very clear that I would get vaccinated. Hopefully the next time things won't be taken this far [sic] as I saw last week..."

Rafael Nadal is also set to return from injury in Abu Dhabi.

Odell Beckham Jr's father is not happy with the Cleveland Browns wide receiver's numbers this season, and a famous fan shares that sentiment.

Ohio native LeBron James took to Twitter to voice his frustration at Beckham's production, though, like the wideout's father, he appears to not blame the man himself.

The four-time NBA MVP posted on Tuesday: "OBJ will show again why he's special. WR1 #FreeOBJ."

That tweet followed an Instagram post from Odell Beckham Sr featuring an 11-minute video showing clips of Browns quarterback Baker Mayfield eschewing chances to throw to an open Beckham.

The social media posts came on the day of the NFL's trade deadline, but Beckham is not among the players expected to be moved despite his struggles.

Beckham has 17 catches for 232 yards and zero touchdowns for the Browns since returning from a torn ACL in Week 3.

Those numbers have been somewhat impacted by a shoulder injury to Mayfield, who missed the Browns' Week 7 win over a Denver Broncos because of a torn labrum but returned on Sunday for Cleveland's 15-10 loss to the Pittsburgh Steelers.

Paul George believes the only way is up for the Los Angeles Clippers after he turned on the style in Monday night's clash with the Oklahoma City Thunder.

The Clippers had lost four of their opening five games but snatched victory from the brink of defeat as they clinched a 99-94 victory.

George had topped 40 points twice early in the season, and this time his 32-point haul came in tandem with four team-mates also hitting double figures.

After making just one of nine shots from the field in the first half, George hit 10 of 15 in the second.

"It's my job to go out there and play hard," George said in a post-game news conference. "My team needed me and I just tried to step up for them."

The Clippers turned a 91-82 deficit into a 95-92 lead as Reggie Jackson landed a jump shot that clinched the game, earning an embrace from George.

After a rocky run of form, George is hoping this outcome means the Clippers might be turning a corner.

"I just told him this is the worst that the team can shoot – obviously we could shoot worse than this, but in the real picture this is the worst we can shoot," George said.

"That shot can change [Jackson's] rhythm. That shot right there was really the biggest shot of the night. That could be all the confidence he needs going into the next game to make a shot when we needed him to.

"It was a great moment for me and him. We've both been struggling tonight so to end the game on that note was a good moment."

Coach Tyronn Lue hailed the "miraculous shots" from George, while Nicolas Batum enjoyed the "ugly win".

Batum, who finished with 14 points, was relieved to see the Clippers find their stride.

"I've never seen that before, the whole team getting cold for five games," said the French forward. "The thing is, we're not playing that bad actually.

"We keep playing defense, trying to move the ball, trying to find a way, but we just don't make shots, but we kept fighting, we kept grinding.

"It was just finding a way to win a game tonight. We didn't lose confidence. PG [George] was great in the second half and took us home.

"It was an ugly win, but I'd take an ugly win compared to beautiful losses."

Assessing another standout display from George, Batum said: "We've got to help him out. The last game [a 111-92 loss to the Portland Trail Blazers] was unacceptable as a team.

"He got 42 and he got 50 per cent of the points. We've got four guys in double figures tonight and that's how we have to do it every night. We can't rely on him to get 30-40 points every night."

After missing out on their first chance to close out the World Series against the Houston Astros on Sunday, the Atlanta Braves are confident heading into Game 6. 

As the teams prepare to reconvene at Houston's Minute Maid Park on Tuesday, Braves manager Brian Snitker said his side are not feeling any ill effects from their 9-5 home defeat in Game 5. 

Atlanta need just one more victory to win their first World Series since 1995, and Snitker insists the players are showing no signs of letting the pressure affect them. 

"We're in the World Series right now. There's no pressure," Snitker told a news conference Monday. "Like I say, it's pressure in the NLCS when you're trying to get here. We all want to finish this off, but there's no pressure.

"We're one of two teams remaining in our sport, and [I haven't] sensed any kind of pressure out of these guys internally. The only time I hear about that is in this [press conference] room. In that room out there, I never hear it."

Six teams have blown a 3-1 World Series lead in a seven-game series, but it has only happened once in the last 36 years: the 2016 Cleveland Indians against the Chicago Cubs. 

The Braves will feel good about their chances of avoiding a similar fate primarily because they can expect to get significant innings out of their starting pitchers in Game 6 and, if needed, the decisive Game 7. 

Thanks to a lack of depth in their rotation exacerbated by the loss of veteran Charlie Morton to a broken leg suffered in Game 1, the Braves have had to start relief pitchers each of the last two games. 

Dylan Lee faced just four batters in Game 4 before Kyle Wright picked up the slack with an impressive 4.2 innings of relief work, while Tucker Davidson recorded only six outs on Sunday. 

The Braves will send Max Fried to the mound Tuesday, giving him another chance against the Astros after a rough start in Atlanta's Game 2 defeat.

"I expect to see Max on top of his game tomorrow," Snitker said. "I expect that every time he goes out. I mean, this guy probably, since the All-Star break, is one of the best pitchers in the game. So that's kind of the version of Max that I expect to see tomorrow."

Fried also got knocked around in his NLCS Game 5 start against the Los Angeles Dodgers, but the 27-year-old said he views what will be his final start of the season as a chance at redemption. 

"Any time that you go out there and you don't perform the way that you want, you don't win, you want to go back out there and redeem yourself," Fried said.

"I'm ready to go out there and leave it all on the field. It's probably going to be my last outing of the year, so there's nothing to hold back."

The NBA's hottest young scorer got the best of the reigning MVP on Monday as Ja Morant and the Memphis Grizzlies defeated Nikola Jokic's Denver Nuggets 106-97. 

Morant had 26 points, eight assists and seven rebounds for the Grizzlies, who bounced back from an ugly home loss to the Miami Heat on Saturday. 

The 22-year-old Morant is averaging 28.3 points per game, second only to Stephen Curry of the Golden State Warriors (28.7), while shooting 52.4 per cent from the field. 

Jokic played a team-high 33 minutes and finished with 23 points, seven rebounds, seven assists and four blocked shots. 

The Nuggets superstar has shown no ill effects from the knee contusion that forced him out of a game against the Utah Jazz last week in the second quarter. 

The teams meet again in Memphis on Wednesday. 

Short-handed 76ers top Trail Blazers

Joel Embiid missed the game with a planned rest day and Tobias Harris sat out due to health and safety protocols, but the Philadelphia 76ers still managed to defeat the Portland Trail Blazers 113-103 behind 23 points from Seth Curry and 21 off the bench from Georges Niang. Embiid's replacement, Andre Drummond, added 14 points and 15 rebounds for the 76ers as Damian Lillard and CJ McCollum combined to make just 15 of 40 shots from the field, including five of 17 from three-point range, for Portland. 

After making just one of nine shots from the field in the first half, Paul George hit 10 of 15 in the second to finish with 32 points and lead the Los Angeles Clippers past the Oklahoma City Thunder 99-94. Shai Gilgeous-Alexander had 28 for OKC. 

The Chicago Bulls outscored the Boston Celtics 39-11 in the fourth quarter to rally for a 128-114 road victory. DeMar DeRozan had a spectacular shooting game, making 15 of 20 from the field to lead the Bulls with 37 points while Zach LaVine added 26. 

OG Anunoby had 36 points as the Toronto Raptors handed the New York Knicks their second loss of the season, 113-104 at Madison Square Garden. Gary Trent Jr. added 26 for Toronto, while RJ Barrett led New York with 27 points.

Beal, Wizards suffer second loss

Bradley Beal made only three of 11 shots from three-point range and the Washington starting lineup attempted just five free throws as the Wizards suffered their second defeat of the season, 118-111 to the Atlanta Hawks. 

New Orleans Pelicans star Zion Williamson will miss at least two to three more weeks as he continues to recover from a right foot injury. 

Williamson had surgery during the offseason to repair a broken foot and has missed the start of the regular season for the second time in his three NBA campaigns. 

The Pelicans are 1-6 so far without him but head coach Willie Green told reporters on Monday his star is making progress. 

"He's cutting. He's doing explosive work. He's running. He's getting closer and closer," Green said.

"It's just one of those injuries where we want to be really diligent, especially with the foot, of being careful when we put him back on the floor at full go."

Williamson has not yet been cleared for contact, so he has not been able to participate in five-on-five drills during practice. 

He will accompany the team on their four-game road trip that begins in Phoenix on Tuesday against the Suns, with his next set of scans scheduled for two to three weeks from now. 

"We’ll know more after that," Green said. "But he’s progressing. It’s a good sign for us. We want to continue to keep him going in that direction."

Williamson averaged 27.0 points, 7.2 rebounds and 3.7 assists per game across 61 appearances last season for the Pelicans.

Canada sensationally upset top-ranked France on day one of the inaugural Billie Jean King Cup, winning a decider in the doubles to secure victory at the O2 Arena in Prague on Monday.

The tournament, formerly known as the Fed Cup, kicked off in exciting fashion with three of the four ties going to a final rubber match.

The most notable result of the day came in Group A as the lowest-ranked team Canada beat the reigning champions France 2-1. A singles win for world number 353 Francoise Abanda against Fiona Ferro was followed by the pairing of Gabriela Dabrowski and Rebecca Marino defeating Clara Burel and Alize Cornet to clinch it.

Elsewhere, Group D began with hosts Czech Republic beating Germany 2-1, despite world number three Barbora Krejcikova losing to world number nine Angelique Kerber in the second match.

The Czechs have won six of the last nine Fed Cups, and will be hoping to reclaim the crown in their home tournament.

History was made by Belgium's Greet Minnen in Group B as she became the first person to win a match in the competition’s new format, beating Iryna Shymanovich of Belarus 6-2 6-2. Elise Mertens sealed the win for the Belgians immediately after, though Belarus won the dead rubber doubles contest.

In Group C, Spain were able to overcome Slovakia in their deciding doubles match as Sara Sorribes Tormo and Carla Suarez Navarro beat Viktoria Kuzmova and Tereza Mihalikova.

Day two sees Canada take on the Russian Tennis Federation, while Australia start their tournament against Belgium, Slovakia face USA, and Germany will look to get back on track against Switzerland.

Andy Murray was defeated in the first round of the Paris Masters on Monday following a three-set battle with Dominik Koepfer.

Murray, given a wildcard entry, was initially drawn against Jenson Brooksby but the American withdrew just a couple of hours before the match was due to start because of an abdominal injury.

The three-time major singles champion instead faced German Koepfer, who triumphed 6-4 5-7 7-6 (11-9) in a contest lasting just over three hours.

Lucky loser Koepfer, in his debut in the main draw, served for the match at 5-3 in the second set but was broken to love as the contest turned topsy-turvy.

Murray had seven match points in the decider, including five in the tie-breaker, but the 2016 champion could not convert and left the court looking disconsolate.

"I was about to go back to the hotel and then one of the ATP Tour Managers texted me, 'Dom, you in? You're playing against Andy Murray'," Koepfer said. "Honestly, I was a little nervous.

"I didn't expect to play today, I was hoping that someone was going to pull out tomorrow. But a night match here in Paris, a lot of fans, they had an unbelievable crowd, the first time for me for a while. It's been a great day. Unexpected, but it worked out and I'm happy."

There was more disappointment for the United Kingdom as Dan Evans saw a strong start yield nothing as he lost in three sets to Alexander Bublik, who goes on to face sixth seed Casper Ruud.

Djokovic set for Fucsovics test

World number one Novak Djokovic will begin his campaign against Marton Fucsovics, who outlasted Fabio Fognini in a match lasing nearly two hours and 45 minutes.

Fucsovics dominated the first set but was engaged in a far tougher battle for the rest of the contest before winning 6-1 6-7 (6-8) 7-6 (7-5).

The Hungarian is 0-3 against Djokovic in his career, last losing to the 20-time major winner at the quarter-final stage of Wimbledon. The winner of this latest contest could face a last-16 meeting with Adrian Mannarino, who won in straight sets against Nikoloz Basilashvili.

Ilya Ivashka overcame Albert Ramos-Vinolas to secure a meeting with second seed Daniil Medvedev, while Dusan Lajovic will face Alexander Zverev after defeating Mackenzie McDonald.

Norrie brings up Tour century to keep Finals in sight

Tenth seed Cameron Norrie kept his chances alive of qualifying for the ATP Finals after a commanding 6-2 6-1 defeat of Federico Delbonis.

The Briton's victory, his 100th on the Tour, could help him to close the gap in the race for the year-ending tournament in Turin. Norrie started the week in 11th place, 140 points adrift of Jannik Sinner in the eighth and final automatic qualifying spot.

"It's obviously a great milestone and it shows I have been on the Tour and have a little bit of experience now," said Norrie. "It's a nice bonus, but there is a lot of tennis in the year to be played. It's a great achievement."

One man who will not qualify for the Finals is Aslan Karatsev. Last month's champion in Moscow lost in three sets to American Sebastian Korda, meaning he cannot now catch the top eight.

Rafael Nadal intends to make his Tour comeback next month and plans to play at the 2022 Australian Open.

The 20-time major champion has not played since a defeat to Lloyd Harris at the Citi Open in August.

The 35-year-old, who withdrew from Wimbledon and the Tokyo Olympics after losing to Novak Djokovic in the French Open semi-finals, also pulled out of the US Open due to a recurring foot injury.

Nadal has spent time training in Mallorca this month following treatment in Barcelona and said he was not sure when he would make his return to action.

Speaking at a sponsor event in Paris, Nadal said he hopes to play at the World Tennis Championship next month before a possible tilt at the first grand slam of next year, an event he has won just once back in 2009.

"My plan is to play Abu Dhabi in December and then in a tournament before Australia and then the Australian Open. That's my goal," Nadal said. "We're working hard to make it happen.

"The injury in my foot still needs to get a little better, but I'm already training almost an hour and a half a day so that's positive. Some days are better than others, but I'm starting to have a lot more positive days than negative ones.

"So, I'm on the right track. I'm training, I'm feeling better. I'm back on the court."

World number eight Casper Ruud and world number 13 Denis Shapovalov are two of the big names from the ATP Tour to have confirmed they will play in Abu Dhabi in the event that runs from December 16-18.

Women's Olympic gold medallist Belinda Bencic and surprise US Open champion Emma Raducanu have also signed up to make their tournament debuts.

The Australian Open, won this year by Novak Djokovic, is due to start on January 17.
