Top overall seed at the Winston Salem Open, Grigor Dimitrov, won the first set of his opening match against Dominic Thiem 6-0 before being forced to retire due to illness symptoms while trailing 4-2 in the second.

The first set was total domination from the Bulgarian, winning 80 per cent (12-of-15) of the points against Thiem's serve as he breezed through the opening frame in 25 minutes, but after experiencing dizziness and shortness of breath in the second set, he decided to pull the plug on his match after a visit from the doctor.

Thiem will play England's Jack Draper in the next round after he was too strong down the stretch for Italy's Fabio Fognini, winning 6-2 4-6 6-1.

Meanwhile, it was relatively smoother sailing for second second Botic van de Zandschulp in his all-Dutch matchup against Tallon Griekspoor, converting both of his two break point opportunities to win 7-6 (7-5) 6-3.

Earlier in the day, in-form Belarusian and 11th seed Ilya Ivashka used his powerful serve to overwhelm Germany's Peter Gojowczyk 6-4 6-2. 

Ivashka will meet Switzerland's Marc-Andrea Huesler next after the world number 102 passed a stiff test against Sweden's Mikael Ymer, with his 6-4 6-4 win likely elevating him into the top-100 when the next rankings are released.

Richard Gasquet at 36 years young upset 20-year-old Italian Lorenzo Musetti 7-6 (7-5) 4-6 6-1, and he will play Steve Johnson next after the big American defeated Spain's Pedro Martinez 7-6 (7-2) 6-2.

Serbia's Laslo Djere needed almost three hours to get the better of Portugal's Joao Sousa 4-6 6-3 7-6 (7-5), and Djere will play Australia's Jason Kubler after he handled South Korea's Kwon Soon-woo 7-5 6-2.

The other two Aussies in action were less successful, as John Millman fell 6-4 6-4 to Spain's Albert Ramos-Vinolas, and James Duckworth went down 6-3 6-3 against Maxime Cressy.

Finland's rising star Emil Ruusuvuori was disappointing in his 6-4 6-1 loss to France's Adrian Mannarino, and fellow Frenchman Benjamin Bonzi also got the job done against England's Kyle Edmund 6-4 7-6 (7-5).

In the late session, 15th seed Jaume Munar defeated Tseng Chun-hsin 6-3 6-4, and in the last match of the night, Lorenzo Sonego beat Alejandro Tabilo 7-5 6-1.

Aliaksandra Sasnovich was the top seed to advance in Tuesday's action at Tennis in the Land, treating the Cleveland crowd to a two-and-half-hour battle before prevailing 4-6 6-3 6-3 against Sara Sorribes Tormo.

In a close contest, Belarus' Sasnovich took advantage in the big moments, winning five of her 10 break point opportunities, while Sorribes Tormo could only convert two-of-nine.

While seventh seed Sasnovich was the highest-seeded winner on the day, fifth seed Irina-Camelia Begu fell victim to a shock 6-3 6-2 upset from world number 415 Sofia Kenin.

Kenin, a wildcard, now advances to the quarter-finals after winning two matches in a row for the first time since January, and prior to this week she had lost her previous nine matches.

Alize Cornet will likely meet second seed Martina Trevisan in the quarter-final after a strong 6-3 7-6 (7-1) triumph against Denmark's rising 19-year-old talent Clara Tauson.

Liudmila Samsonova needed only 59 minutes to breeze past Iryna Shymanovich 6-1 6-0, and it was similarly smooth sailing for Magda Linette as she defeated Sorana Cirstea 6-4 6-2.

Meanwhile, at the Granby Championships in Canada, only one match was able to finish before the rain halted the rest of the day's play.

Spain's Nuria Parrizas-Diaz was too much for England's Harriet Dart, winning 6-2 6-4, while top seed Daria Kasatkina will just need to add the finishing touches when she resumes her match against Magdalena Frech, leading 6-3 5-0.

The Los Angeles Dodgers already knew they would not have Walker Buehler available to pitch this season, and now it appears he will have to sit out all of their 2023 campaign as well. 

Buehler, 28, underwent Tommy John surgery and a repair to his flexor tendon on Tuesday and is unlikely to pitch next season. The news comes after the Dodgers announced in June that the right-hander would undergo an elbow procedure that would end his 2022 season. 

This is the second Tommy John surgery for Buehler, who also had the operation done not long after he was selected in the first round of the 2015 draft. He missed the remainder of that season and virtually all the following year in recovery, making three brief appearances late in his first full pro season. 

Tommy John recoveries typically take upwards of 14 months, and Buehler’s rehab could take longer due to his personal injury history, as the second Tommy John procedure is known to be a slower recovery process. 

Buehler was 6-3 with a 4.02 ERA in 12 starts over 65 innings this season, and made his final appearance at San Francisco on June 10.  

He went 16-4 with a 2.47 ERA last season and finished fourth in voting for the NL Cy Young Award. 

Los Angeles Chargers cornerback and prized free agent acquisition J.C. Jackson underwent ankle surgery on Tuesday.

The 2021 Pro Bowl selection is expected to miss two-to-four weeks, the team announced, giving him a chance to suit up for the Chargers' season opener against the Las Vegas Raiders on September 11.

After starting his NFL career with the New England Patriots, Jackson signed a five-year, $82million contract with the Chargers this offseason.

Jackson, who went undrafted out of Maryland in 2018, had 25 interceptions in his four seasons with the Patriots, the most in the NFL over that span.

Jackson, 26, was signed by the Chargers in an effort to improve on last year's bottom-five scoring defense that allowed 27 points per game.

This offseason, Los Angeles also traded for Khalil Mack to rush the quarterback opposite Joey Bosa, while the interior defensive line should be bolstered by the acquisitions of Sebastian Joseph-Day and Austin Johnson.

The Chargers made Derwin James the highest-paid safety in NFL history when they signed him to a $76.5m contract extension earlier this month.

With a talented, new-look defense and with blossoming star Justin Herbert under center, the Chargers are looking to challenge the Kansas City Chiefs in a highly competitive AFC West.

Manchester City striker Erling Haaland has cited "insanely good" Karim Benzema as inspiration as he vows to never stop improving at the Etihad Stadium.

Haaland has made a solid start to life in England since his £51million (€60m) move from Borussia Dortmund, scoring three goals in as many Premier League games for the reigning champions.

City pipped some of the world's biggest clubs in the race to secure the services of the Norway international, including reigning LaLiga and Champions League winners Real Madrid.

Madrid talisman Benzema played an instrumental role during their successful 2021-22 season - top-scoring in both competitions along the way - while he recently surpassed Raul (323) as the club's second-leading marksman of all-time behind only Cristiano Ronaldo (450).

The 34-year-old appears certain to be in the running for the top prize at this year's Ballon d'Or awards, and his recent exploits have provided inspiration for a player 12 years his junior.

"I don’t know what will happen, but it must always be about learning, about developing," Haaland told FourFourTwo. "You can never stop looking for new ways to become better.

"Look at Karim Benzema at Real Madrid. He's 34 now and suddenly, he's developed into an even better player over the last couple of years – that's insanely good. I want to always do that."

Everton manager Frank Lampard has stated that nothing has changed on the future of Anthony Gordon amid strong links of a move away from Goodison Park.

It has been reported that Chelsea could be ready to pay up to £60million to take the 21-year-old to Stamford Bridge, while Tottenham and Newcastle United have also apparently been interested.

After the departure of last season's top goalscorer Richarlison to Spurs and the injury to striker Dominic Calvert-Lewin, it has fallen on Gordon to lead the line at the start of this campaign.

Gordon started on the bench for Everton's EFL cup game with Fleetwood Town and Lampard opted not to bring him in on in the 1-0 victory, amid rumours that Chelsea are preparing a new bid having reportedly already seen multiple offers exceeding £40million rejected by Everton.

But Lampard says that nothing has changed yet, telling Talksport: "He's our player and the latest is the same as what I said after the game against Nottingham Forest.

"He's our player and he's got three years left on his contract. We're aware of the interest of Chelsea as the world is now.

"This situation has to be right for Everton Football Club and for me as the coach of the team so we're in the same position that we were a few days ago."

Benfica eased through to the Champions League group stage with a 5-0 aggregate thrashing of Dynamo Kyiv on Tuesday, while Maccabi Haifa and Viktoria Plzen also qualified.

The three teams will now look ahead to the draw on Thursday when they will find out who they will be facing in the group stage.

Last season's quarter-finalists Benfica built on an impressive 2-0 first-leg victory against a rusty Kyiv side with first-half goals from Nicolas Otamendi, Rafa Silva and David Neres essentially killing the tie by half-time at Estadio da Luz.

Meanwhile, Haifa scored late on to earn a thrilling 5-4 aggregate comeback win over Red Star Belgrade in Serbia to reach their first Champions League group stage since the 2009-10 season.

A 90th-minute own goal from Red Star striker Milan Pavkov was enough to progress the Israeli side, who had been 2-0 down on the night after winning the home leg 3-2.

Haifa will be joined in Thursday's draw by Plzen, who also advanced after coming from behind to beat Qarabag 2-1 on aggregate.

A first-half goal from Filip Ozobic had put the Azerbaijani side in front after a goalless first leg, but Jan Kopic and Jan Kliment bagged after the interval to turn the game around and get their team into the group stage of the competition for the first time since the 2018-19 campaign.

Retiring legend Serena Williams has indicated she "will always have some sort of involvement" in tennis as she prepares for the US Open, in what will be the final Grand Slam of her career.

The 40-year-old has won 23 major singles titles, while also adding 14 doubles championships in a brilliant career, but will be hanging up her racquet after she plays in the tournament she has won six times.

Her first time lifting the US Open trophy came in 1999, but even after spending over two decades at the top level of the sport, Williams says she will continue to be active in tennis.

"I will never retire from something I absolutely love," the American told Meghan Markle on the Duchess' new Spotify podcast.

"I will always have some sort of involvement in it. Maybe not professionally, but I will always want to be involved in some form in tennis. Obviously, I’ve retired professionally, but it’s also an evolution."

Williams also outlined her plans for the future, adding: "I really want to expand my family, and you know I’ve been putting it off for so long.

"As a woman, there’s only so long you can put that off and other people out there, other men out there, can continue to play. My best is being a mom; I think I can do really good at that."

Fellow tennis legend John McEnroe has heaped praise on Williams ahead of the tournament at Flushing Meadows, commenting: "The way that she moves the needle when she plays, it's like Tiger Woods and golf.

"You can look at the accomplishments, she has the Grand Slam victories. Off the court, I know that she's had a lot of difficulties in her life that she talks about in her own documentaries, but she has come out the other end as this icon, global superstar.

"Her story alone, what she represents as someone who's an African-American girl who came from a tough situation, and became the greatest player that ever lived. What that represents for us, and maybe around the world, is an opportunity that it can happen to anyone potentially."

Mohamed Salah has "a year to prove" himself worthy of the new bumper deal handed to him by Liverpool, believes former Netherlands international Nigel de Jong.

The Egypt international put an end to long-running speculation about his future in July by signing a fresh three-year contract to take him through to 2025 at Anfield.

With Sadio Mane having departed for Bayern Munich, the move represented a major part of Liverpool's off-season transfer business to keep one of the key figures of the Jurgen Klopp era on Merseyside.

But a slow start to the season for Liverpool has seen Salah among others come in for criticism, with the forwatd's second goal of the new Premier League campaign on Monday against Manchester United not enough to stave off a 2-1 defeat for the Reds.

With just two points from their first three games, Liverpool are already arguably facing an uphill battle in the title race with Manchester City, and now De Jong has opined that Salah is on limited time to justify the faith shown in him.

"If I was the sporting director and I'd just extended the contract of probably the best player in my squad, I'll give you a year to prove yourself," he told beIN SPORTS.

"Are you worth another [three] years? You need to produce the same numbers, especially on the wages he's on.

"I think it's really important for Salah, and also for Liverpool, to find a way to be successful together in order to strive for him to stay at Liverpool for a long time. If not, they have to make a decision as well.

"I've said it many times over the past couple of years: Mane is the soul of the team. He is a complete player in his energy, in producing numbers, in the way he strides forward.

"Of course, I'm not saying Salah isn't a great player, but he's staggering when it comes down to the numbers."

Dries Mertens says his time at Napoli "could have ended differently" after he departed the club at the end of last season following a breakdown in contract negotiations.

The Belgium international ended a nine-year spell in Naples ahead of the new campaign after failing to agree fresh terms with the Serie A side, subsequently moving to Super Lig outfit Galatasaray on a free transfer.

The 35-year-old was an integral presence for the club over the best part of a decade, helping them to two Coppa Italia triumphs and a further Supercoppa Italia crown during his tenure.

Reflecting on his exit, Mertens revealed he has kept his family home in the region, while acknowledging that had discussions started earlier, he may well have stayed on Napoli's books.

"It's been a wonderful nine years," Mertens told DAZN. "Of course, it could've ended differently. I think the club could've talked about [the contract] earlier. I hope I can learn from this experience to become even greater. 

"Today I'm very happy because my family and I have embarked on a new adventure. I'm in a great city and a great club. 

"[But] of course leaving Napoli was hard. My wife cried at the thought of leaving home, so we decided to keep it and try to spend as much time there as possible."

Mertens, a Belgium centurion, will have his eyes likely set on securing a place in the national team squad for the World Cup in Qatar later this year.

John McEnroe has called Novak Djokovic's potential absence from the US Open over his vaccination status a "joke".

The United States does not currently allow those who have not received the COVID-19 jab into the country, putting the unvaccinated Djokovic in real danger of missing this year's edition of the tournament he has won three times.

The Serb has already missed the Australian Open this year because of his lack of vaccination, while also missing tournaments at Indian Wells in California, as well as the Rogers Cup in Canada.

He did however win his 21st Grand Slam at Wimbledon earlier this year, and McEnroe believes Djokovic should be allowed to play at Flushing Meadows as he chases down Rafael Nadal for the most Grand Slam titles in history.

Ahead of the tournament in New York, McEnroe told reporters: "No, I don't think it's fair. I think it's a joke.

"I would have had the vaccine and gone and played but he's got very strong beliefs and you have to respect that. 

"At this point, in the pandemic, we're two and a half years in, I think people in all parts of the world know more about it, and the idea that he can’t travel here to play, to me is a joke."

On whether Djokovic's decision not to get the vaccine could affect his competition with Nadal and Roger Federer to become the most decorated male player ever, McEnroe replied: "That's the question that we all want to know the answer to.

"Obviously, Rafa Nadal has benefited from that. These three guys are already above everyone else. So, it makes it extremely interesting to see these two go at it and then you think of Roger Federer but he's been hurt for a while."

However, McEnroe believes Djokovic can overcome his vaccination status to win more titles, adding: "Who's to say [Djokovic] can't do it for another couple of years?

"Let's say that he wins three or four more. That's not impossible, by any means. Despite this, he can still get to 25. I think it's made it more complicated to do it because that has to wear on you mentally.

"Training this past month or six weeks not knowing whether he's going to play, that's going to put a strain on you mentally just as it was when he got thrown out of Australia. I think it took him three, four months to get his head right."

Toni Kroos intends to finish his career at Real Madrid, while the former Germany international says he will not reverse his decision to retire from the national team ahead of Qatar 2022.

The veteran playmaker has completed a clean sweep of major honours with the LaLiga giants since arriving from Bayern Munich in 2014, shortly after helping Die Mannschaft to World Cup glory in Brazil.

Yet having hung up his boots for the national side following last year's Euro 2020 last-16 exit at the hands of England, Kroos admits he may well follow suit at domestic level sooner rather than later.

However, he will not be looking to wrap up his time on the pitch anywhere other than Santiago Bernabeu, regardless of time frame.

"I believe that the year 2023 is appropriate [to retire]," Kroos told Bild. "I will be 33 years old.

"I will decide whether I will renew for a season or two. That is still open for discussion, but I am completely sure that I will retire at Real Madrid."

Kroos will not walk back his decision to depart the national team, however, with the 106-cap veteran having no intention of making himself available for Hansi Flick's squad.

"The decision I made at that time stands," he added.
