Defending Rotterdam Open champion Andrey Rublev and world number four Stefanos Tsitsipas won through their opening tests, but Denis Shapovalov will not be in round two.

Rublev beat Henri Laaksonen 6-4 6-4 on Tuesday, while top seed Tsitsipas went the distance before edging out Alejandro Davidovich Fokina 7-5 6-7 (1-7) 6-4 after two hours and 39 minutes on the court.

Reflecting on his win, Tsitsipas was full of praise for his opponent, saying: "It was a great battle; he gave me some of the best tennis I have seen him play.

"He was very fired up today and making the best out of every single shot. He was hitting huge winners from behind the baseline. He's one of the best young players who I have played."

However, world number 12 Shapovalov had no such luck, as he slumped to a surprise defeat to Czech qualifier Jiri Lehecka.

The world number 137 saw off the Canadian 6-4 6-4, showing impressive resolve to hold serve at 4-2 in the first set after initially going 0-40 down.

Shapovalov converted just one of 11 break points offered up by Lehecka as he failed to build on an impressive run to the Australian Open quarter-finals last month.

Aslan Karatsev, who won a title in Sydney in January, was another seed to drop out, after his 2-6 7-6 (7-2) 7-6 (7-0) defeat to home favourite Tallon Griekspoor.

Griekspoor has enjoyed some big wins in this tournament in the past, having defeated Stan Wawrinka and Karen Khachanov in 2018 and 2019 respectively.

Khachanov, too, was in action on Tuesday; unlike his Russian compatriot Karatsev, Khachanov took his place in round two with a 6-7 (4-7) 6-1 7-6 (7-6) defeat of Alexei Popyrin.

Lorenzo Musetti and Dutchman Botic van de Zandschulp also progressed.

CJ McCollum sealed a move to the Pelicans ahead of the NBA trade deadline as New Orleans and the Portland Trail Blazers announced an initial seven-player deal.

The agreement ends McCollum's long and successful stay with Portland, who acquired him with the 10th overall pick in the 2013 draft.

The 30-year-old shooting guard is averaging 20.5 points, 4.3 rebounds and 4.5 assists in an average 35.2 minutes per game this season. His field-goal record (.436) and three-point shot success rate (.384) are both slightly down on his career averages (.453 and .396).

The Pelicans announced his signing in a statement that read: "The New Orleans Pelicans announced today that the team has acquired CJ McCollum, Larry Nance Jr and Tony Snell in a trade with the Portland Trail Blazers.

"In exchange, New Orleans has conveyed Nickeil Alexander-Walker, Josh Hart, Didi Louzada, Tomas Satoransky, a protected 2022 first round draft pick, and two future second round draft picks."

Including the ongoing campaign, McCollum has averaged at least 20 points per season for each of the last seven years with Portland.

In early December, the Trail Blazers revealed McCollum had suffered a collapsed right lung. He missed 18 games, returning for a January 17 win over the Orlando Magic.

Portland interim general manager Joe Cronin said: "On behalf of the Trail Blazers organisation, I want to thank CJ McCollum for the integral role he has played in the success of the franchise over the last nine seasons and for his countless acts of service to the Portland community.

"CJ has cemented himself in Trail Blazers history with his elite skill level and memorable moments on the court as well as with the work ethic, professionalism and generosity he displays behind the scenes."

Juan Martin del Potro was reduced to tears in what he expects to be his final tennis match as the former US Open champion bowed out of the Argentina Open.

The 33-year-old Argentinian lost 6-1 6-3 to fellow Argentinian Federico Delbonis in Buenos Aires, having come back from four rounds of knee surgery to get back on court.

He saved seven of 12 break points in a determined effort against Delbonis, but Del Potro, who had been on the injured list since June 2019, was in no shape to compete for victory over his compatriot.

One of the most popular players on the tour, who might have achieved many more great things had wrist and knee trouble not played him over the last decade, Del Potro bid an emotional farewell.

The moment got to Del Potro as he prepared to serve at 5-3 down in the second set. His emotions spilled out, with a towel failing to mask his tears as a passionate crowd rallied behind him, chanting: "Ole, ole, ole, ole, Delpo, Delpo."

A fan carried a flag bearing the message: "The Tower of Tandil keeps fighting. Thank you." Tandil is Del Potro's home city.

After the match, Del Potro said: "The truth is that this is a moment I never wanted to come. Health leads me to have to make a decision: I made too much effort in these two and a half years.

"Sometimes I can lose. I do not have the strength that everyone believes. I think I fulfilled all the dreams in tennis and the most difficult thing to achieve, which is the affection of the people.

"I feel like I've given it all. This is a day I never wanted to come, but I'm going to remember it for the rest of my life."

He was relieved to be leaving on his own terms, saying: "Now I am calm because my last match was possibly on the court and not in a press conference. I will always remember this."

Del Potro, whose US Open triumph came when he beat Roger Federer in a sensational 2009 final, has accepted a wildcard to the upcoming Rio Open, but he signalled he is unlikely to now take that up.

"Yes, I was planning to go to Rio," he said, quoted by La Nacion. "But... I think I already gave everything until the last point."

Del Potro was an Olympic silver medallist in 2016, beaten in the Rio final by Andy Murray, and later in the same year he helped Argentina win the Davis Cup.

It was fitting that Delbonis, who won the decisive rubber against Croatia after Del Potro was victorious in both his singles matches, was the man on the other side of the net on Tuesday. He and Del Potro shared a long, affectionate hug at the net at the end of the match.

Del Potro's mother, Patricia, was among those in the crowd. The ATP said it was the first time she had attended one of his matches. She was pictured embracing her son off court after the match ended.

Other matches happened in Buenos Aires on Tuesday too, a highlight being Brazilian Thiago Monteiro's 6-3 6-3 win over seventh seed Albert Ramos-Vinolas.

At the Dallas Open, first-round winners included Jack Sock, Jordan Thompson and Liam Broady.

Bradley Beal will sit out the remainder of the NBA season to undergo wrist surgery.

Washington Wizards guard Beal, who can become a free agent at the end of the season, has sat out the past four games and will not return after deciding to go under the knife to repair a torn scapholunate ligament of his left wrist. 

"Despite the last 10 days of getting intensive treatment and rehab on my wrist, it became clear that I would not be able to compete to my standards or to the level that our team and our fans deserve," said Beal. 

"I'm disappointed to have my season end this way, but we all agreed that this was the best decision. I look forward to coming back at 100 per cent and continuing to lead this team as we work together to build toward the future." 

The All-Star is eligible for a five-year $245million extension with the Wizards in the close season. He also has a $36.4m player option for next term. 

Beal had been heavily linked to a trade before Thursday's deadline, but that now appears unlikely. 

He was rumoured to be a target for Philadelphia 76ers as they continue to look to offload Ben Simmons, while the Atlanta Hawks and New York Knicks had also been touted as potential trade candidates. 

Beal was averaging 23.2 points, 6.6 assists and 4.7 rebounds. 

Domantas Sabonis is reportedly being sent to the Sacramento Kings by the Indiana Pacers, who will acquire Tyrese Haliburton as part of a six-player trade. 

According to ESPN, the Pacers will also receive guard Buddy Hield and center Tristan Thompson in exchange for two-time All-Star Sabonis. Jeremy Lamb, Justin Holiday and a 2027 second-round pick will head to the Kings. 

It is expected that Indiana's decision to part with Sabonis reduces the chances of Myles Turner departing before Thursday's trade deadline, given he can now play a bigger role at center. 

Sabonis is averaging 18.9 points, 12.1 rebounds and 5.0 assists per game in 2021-22. Only Rudy Gobert (15.1), Nikola Jokic (13.7) and Clint Capela (12.2) average more rebounds per game than Sabonis, whose 34 double-doubles this season ranks him third in the league. 

The Kings had to give up Haliburton to get the deal done, with the 12th overall pick from the 2020 draft having been expected to be a key player for the franchise for years to come. 

Haliburton's 1.69 steals per game this season is the sixth best in the league, while he sits 11th for assists per game with 7.4. He is also averaging 14.3 points and 3.9 rebounds. 

They have also given up Hield, who has made 3.3 three-pointers per game this season. Only Stephen Curry (4.8) and Fred VanVleet (3.9) average more.  

Maria Sakkari, Jelena Ostapenko and Petra Kvitova all avoided upsets as the seeds continued to march on at the St Petersburg Ladies Trophy on Tuesday.

Top seed Sakkari beat Anastasia Potapova 6-4 6-4 to advance to the last 16, while seventh seed Ostapenko was a 6-1 6-4 winner against wildcard Wang Xinyu.

Kvitova, the 2018 champion, took just an hour and nine minutes to see off qualifier Jule Niemeier 6-2 6-1, with the sixth seed and two-time former Wimbledon winner making a positive first appearance since being eliminated from the Australian Open in round one.

Sakkari, Ostapenko and Kvitova followed fellow seeds Anett Kontaveit, Belinda Bencic and Elise Mertens - winners on Monday - in avoiding an early exit.

However, number four seed and home favourite Anastasia Pavlyuchenkova was forced to withdraw from the competition on Tuesday due to a knee problem.

Bernarda Pera replaced the Russian in the main draw and fell 7-6 (7-3) 6-4 to Jaqueline Cristian, who will next face Aliaksandra Sasnovich.

That is after Sasnovich held firm to beat Magda Linette 7-5 4-6 6-4 in a tight contest, with a decisive break in the fifth game of the third set seeing her through.

Max Verstappen insists he fully deserved his Formula One world championship triumph and does not believe the achievement has been overshadowed by the ongoing controversy around the title-deciding race.

The 24-year-old clinched his first title by pipping seven-time champion Lewis Hamilton on the final lap of the Abu Dhabi Grand Prix in December.

Hamilton had built up a healthy lead over his Red Bull rival in the season finale, with both men having entered the race level on points, until a controversial late safety car period was followed by Verstappen overtaking the Mercedes driver on the final lap.

Mercedes were furious with how race rules were applied in a safety-car situation and challenged the result, believing Hamilton was unfairly prevented from winning the race and the championship when Verstappen passed him with only a few corners remaining.

The FIA last month announced a "detailed analysis" of the contentious ending has started, with the result of the inquiry to be released before this season's first race in Bahrain on March 20.

Regardless of the verdict reached by the sport's governing body, Verstappen does not believe the controversy detracts from his triumph.

"[The FIA] can't do anything," Verstappen told The Guardian.

Asked if he felt his maiden title triumph has been overshadowed somewhat, the Dutchman replied: "Not at all. I had a very good season and I think I really deserved it. 

"I have been really unlucky as well. People always remember the last race but, if you look at the whole season, the championship should have been decided way earlier."

Verstappen was graciously congratulated by Hamilton following his title-clinching victory in Abu Dhabi, bringing down the curtain on an eventful season that saw both drivers take it in turns to lead the standings.

A low point in the campaign for Verstappen came at the British Grand Prix in July when clashing with Hamilton on the first lap as the home favourite tried to force his way down the inside at Copse Corner.

Verstappen smashed the barriers at 180mph and therefore did not finish the race, with Hamilton finishing first and wildly celebrating his win while his title rival was being examined in hospital.

However, the Red Bull driver did not use that as extra motivation for the second half of the season.

"I don't think we work like that," he said. "It's disrespectful what happened there but we looked at what we could have done better. 

"Once we came back from the break as a team we really did a good job because we won races in the second half of the season we shouldn't have won."

While talk still rumbles on regarding the end of the 2021 season, the new campaign is now just over a month away and Verstappen has a target on his back as defending champion.

"That little pressure in the back of your mind, of having to win a world championship or trying to win it, has gone," he said. 

"It's already happened. I've done it. So when it's tough or you're having bad luck you probably will deal with it easier than normal."

Klay Thompson reflected on reaching a "huge milestone" after bumping up his playing time to 30 minutes in the Golden State Warriors' 110-98 win over the Oklahoma City Thunder.

Regarded as one of the best shooters in NBA history, Thompson has been slowly building up his game time since returning from consecutive ACL and Achilles injuries that left him on the shelf for two and a half years.

He drained two late three-pointers to evoke memories of his Game 6 heroics against the same opponents in 2016 when he nailed 11 three-point efforts – a playoff record.

"That's a huge milestone for myself, and hopefully I can build on it," Thompson said.

"I feel incredible. I feel like I haven't missed a beat only 12 games in."

The majority of Thompson's minutes came in the second half, playing 17.21 in the final two quarters.

Head coach Steve Kerr explained why, saying: "It was awesome just to have Klay back in crunch time. 

"Knowing the defense was going to be heavily slighted toward Steph [Curry] and for him to get free and knock down a couple of shots, it was really fun to see."

An increase to Thompson's playing time will be a welcome relief for Kerr, who is still without Draymond Green, James Wiseman and Nemanja Bjelica, while Andre Iguodala sustained lower back tightness against the Thunder having returned after nine games on the sidelines.

"Meaning we don't have to think about it [rotating]," Kerr said of the boost of Thompson's minutes. 

"Like, we don't have to pull him out. He might be going really well and we can play him a few extra minutes without having to follow really strict guidelines."

Thompson's late efforts were not necessarily in keeping with his performance overall. Prior to those shots he was one-of-six from three-point range (finishing three-of-eight by the end of the game) and was six-of-15 from the floor overall.

But superstar team-mate Steph Curry believes the Warriors will continue to see the very best of Thompson as his minutes gradually increase.

"There's just confidence knowing he still has that instinct and no matter how the game is going up to that point. He's still got the shooter's DNA of the next shot is going in," Curry said. 

"As his minutes ramp up, you'll continue to see those high peaks and Klay going nuts."

LeBron James launched a staunch defence of "brother" and Los Angeles Lakers team-mate Russell Westbrook, insisting "we're all in this together".

Point guard Westbrook has bore the brunt of criticism during a disjointed Lakers season that has left the team below the .500 mark.

Acquired from the Washington Wizards, Westbrook was brought in to play a part in a stellar cast alongside James and Anthony Davis, but things have not worked out too well in LA.

Westwood is averaging 18.4 points (tied 35th), 7.8 rebounds (tied 34th) and 7.7 assists (tied ninth) per game. The 33-year-old was benched for the entirety of overtime in the Lakers 122-115 win over the New York Knicks on Saturday having made just one of 10 field goals.

It was the fifth time in 2021-22 Westbrook made only three field goals or less from 10 attempts, while his numbers in points, rebounds, assists, steals, field-goal percentage and three-point percentages all rank lower than they did with the Wizards last season.

There has even been talk that the Lakers may try and find Westbrook a new home before Thursday's trade deadline, but James said the team's issues cannot be pinned on one player.

"At the end of the day, as his brother, we're all in this together," James told reporters after Monday's practice. 

"We're all in the foxhole together. There is not one guy who is doing it by themselves. There's not one guy you can blame over another guy.

"There's not one guy who gets the praise over another guy. When we lose, we all lose. When we win, we all win. It's really that simple."

The Lakers sit ninth in the Western Conference, three games back of the Denver Nuggets in sixth – a position that guarantees avoiding the play-in tournament for the playoffs.

Part of their issues have centred on injuries, with James and Anthony Davis having both missed significant chunks of the season.

Indeed, Westbrook has only played a combined seven games at the same time as his superstar team-mates this season.

"I haven't been part of a season like this where injuries have played such a toll, but also protocols, false protocols, positive protocols, head coach being out for multiple games," James added. 

"So, it's just challenging, a weird sort of different season for all of us. And not just [for the] Lakers, but a lot of teams in the NBA. So, it's kind of impossible to gauge, I guess, previous encounters that you've had, because it's totally different." 

Head coach Frank Vogel said he has spoken to Westbrook after his overtime decision against the Knicks.

"You still communicate afterwards and there was that today," Vogel said. 

"I've always taken pride with my teams in making sure I'm communicating with guys with whatever happens within a game.

"Obviously not every player, every game, but if a certain thing requires a reach out or just a follow-up then we'll have that."

The Lakers are back in action in a blockbuster showdown against the Milwaukee Bucks on Tuesday.

The New Orleans Saints are set to hire defensive coordinator Dennis Allen as their new head coach to replace long-time leader Sean Payton, according to reports.

Payton stepped away from the head coaching role two weeks ago after the Saints missed the NFL playoffs with a 9-8 record.

Allen previously held the head coach role with the Oakland Raiders from 2014 to 2014 but struggled with a 8-28 record.

Former NFL head coaches Brian Flores and Doug Pederson were also interviewed for the role along with Detroit Lions defensive coordinator Aaron Glenn, Kansas City Chiefs offensive coordinator Eric Bieniemy and their own special teams coordinator, Darren Rizzi.

The Saints have improved drastically in scoring defense since hiring Allen as defensive coordinator in 2015 and are not looking for an overhaul.

"Those eight teams that let go of head coaches, I think their situations are different than ours," Saints general manager Mickey Loomis said prior to the coaching search commencing.

"We had our coach retire with a lot of really good things in place already. That doesn't mean that it can't be improved and built upon. But we don't see it as a wholesale culture change, roster change, anything like that."

Devin Booker top scored with 38 points as the table-topping Phoenix Suns withstood the Chicago Bulls' late charge to win 127-124 on Monday.

Booker shot 14 of 23 from the field including five three-pointers with four rebounds and five assists, while veteran guard Chris Paul contributed 19 points and 11 assists.

The Suns guard reached 30 points for the third time in the past four games as Phoenix won their 13th game from their past 14.

The Bulls charged into contention with a 41-25 fourth-quarter run after the Suns had led by 27 points in the third.

DeMar DeRozan top scored for Chicago with 38 points along with five rebounds and four assists and Zach LaVine returned from injury with 32 points, with six rebounds and eight assists.

Clutch Klay leads Warriors past OKC

Klay Thompson top scored for the Golden State Warriors with 21 points including some clutch three-pointers and Stephen Curry had a near triple-double with 18 points, nine rebounds and 10 assists in a 110-98 win over the Oklahoma City Thunder.

Donovan Mitchell scored 32 points with seven rebounds, six assists and four steals as the Utah Jazz won 113-104 over the New York Knicks, while seven Miami Heat players scored double figures in a 121-100 win over the Washington Wizards.

New All-Star Ball struggles

On the same day he received his debut All-Star call, LaMelo Ball struggled as the Charlotte Hornets went down 116-101 to the Toronto Raptors. Ball shot five-of-19 from the field and one-of-six from beyond the arc for his 15 points, while he also had seven turnovers.

Serbian fifth seed Dusan Lajovic fought back from a set down to triumph over Benoit Paire in the Argentina Open first round while Spanish veteran Fernando Verdasco also progressed on Monday.

Lajovic, who is currently ranked 37th in the world, beat 50th-ranked Paire 4-6 6-4 7-6 (7-3) in just over two hours in Buenos Aires.

In a tight match, the Serbian got the edge in the third-set tiebreak as his first serve seldom let him down.

Former top 10 player Verdasco, now 38-years-old, defeated Bolivian Hugo Dellien 6-4 3-6 6-1 in two hours and two minutes.

Serbian eighth seed Laslo Dere got past compatriot Miomir Kecmanovic 6-4 1-6 6-1, while Argentine pair Federico Coria and Francisco Cerundolo also progressed.

Meanwhile at the Dallas Open, veteran South African Kevin Anderson proved too good for Sam Querrey 6-4 6-4.

The 35-year-old former US Open and Wimbledon finalist sent down 21 aces as he won in little over an hour.

Emerging American Brandon Nakashima defeated Australian John Millman 7-5 7-6 (7-3) in the first round.

The Miami Dolphins have confirmed the appointment of San Francisco 49ers offensive coordinator Mike McDaniel as their new head coach.

McDaniel has joined the Dolphins on a four-year contract according to ESPN, taking over from Brian Flores who was sacked in January.

The Dolphins had been searching for a new head coach for a month, with McDaniel edging out Dallas Cowboys offensive coordinator Kellen Moore.

The Miami job is 38-year-old McDaniel's first head coaching role at any level, having spent 15 seasons in the NFL and two in the UFL.

He was also previously an assistant coach for the Atlanta Falcons, Cleveland Browns, Washington Football Team, Houston Texans and Denver Broncos.

McDaniel replaces Flores who had a 24-25 record after three seasons, including the Dolphins finishing third in the AFC East with a 9-8 record in the 2021-22 season.
