Mercedes driver George Russell has claimed there is "no doubt" that Ferrari and Red Bull "pushed the regulations" during the first half of the Formula One season.

The British driver has seen Mercedes unable to compete with their rivals in the opening months of his stint with the team, having moved from Williams, but the German manufacturers hope for improvement when the season resumes this week.

A new technical directive has been put in place, starting on Sunday in Spa, aimed to crack down on porpoising – with Mercedes among those to have struggled with bouncing throughout the season.

Russell believes that the change could prove to be beneficial to Mercedes and the rest of the pack in the bid to close down on the front two teams, but warned there are no guarantees.

"Spa is going to be interesting. There's changes to some little regulations, which may bring other teams towards us," he told Sky Sports.

"There is no doubt that Ferrari and Red Bull have pushed the regulations in that regard, and we've respected it as the regulation was intended.

"There's no guarantees it will bring them closer to us. Every car is different, but it's not going to help them that's for sure."

Russell currently sits fourth in the driver standings, 100 points behind leader Max Verstappen, while Mercedes are third out of the constructors.

Fernando Tatis Jr. knows "there's no excuses" for a failed drugs that have seen the San Diego Padres shortstop's dreams turn into his "worst nightmares".

Tatis was this month given an 80-game suspension after testing positive for the performance-enhancing substance Clostebol.

The 23-year-old said he tested positive due to taking a skin medication that contained the steroid.

Tatis' ban ensured he will not play in the majors this season and he will also miss the first 32 games of the next campaign.

An All-Star last season after hitting .282 with an NL-leading 42 home runs and 97 RBIs, Tatis has decided to undergo shoulder surgery while serving a ban that he knows he can have no complaints over.

"There's no excuses," Tatis told reporters. "There's no excuses. I need to do a way better job on what is going inside my body. There's no excuse for these actions."

He added: "I have seen how my dreams have turned into my worst nightmares. 

"There's no other one to blame than myself. I haven't made the right decisions these past few weeks, month, even starting at the beginning of the year.

"I have made a mistake, and I regret every single step I have taken in these days. But there's a long way going forward. There's a very long way going forward.

"I'm gonna remember how this feels, and I'm gonna make myself not ever be in this position ever again. I know I have a lot of love that I have to gain back. I have a lot of work to do."

Padres president of baseball operations A.J. Preller says Tatis deserves a chance to make amends.

"Every relationship worth having – there's gonna be some great moments, there's gonna be some challenging moments," Preller said.

"I've talked to Fernando a lot about mistakes. We all make mistakes. I've made plenty of mistakes here as the general manager of this team, as I'm sure Padres fans will let me know from time to time.

"But the key is how you learn from those mistakes, how you grow from those mistakes, what you do going forward."

Tom Brady could have ended up joining the Las Vegas Raiders, but their quarterback Derek Carr is not focusing on what might have been.

UFC president Dana White claimed last weekend he had previously set up a deal for Brady and Rob Gronkowski to join the Raiders, who made the move from Oakland to Las Vegas in 2020.

White claimed he had worked on a deal for Brady to head to the Raiders, rather than join the Tampa Bay Buccaneers, after the veteran left the New England Patriots.

In an appearance on the UFC With the Gronks broadcast on ESPN, White said: "I worked to put that deal together for Brady and Gronk to come to the Raiders. It was almost a done deal. And at the last minute, [Jon] Gruden blew the deal up and said that he didn't want him and all hell broke loose, man. It was crazy.

"And Brady was already looking at houses. It wasn't said yet that Gronk was going to be coming. So Las Vegas would have had Brady and Gronk the year that the Bucs won the Super Bowl except Gruden blew the deal up."

A move for Brady might have signalled the end of the road with the team for Carr, who was drafted by the Raiders in 2014 and has been their starting quarterback since.

Carr, though, is paying little attention to what could have happened, and is instead focused on the here and now.

"It was a moment to put things in perspective," the 31-year-old told reporters. "It really doesn't matter.

"At the end of the day, anything I say will just be blasted out there so I'm just going to completely remove myself and just keep trying to play football. It's been nice just answering football questions.

"Hopefully, no more drama in the city."

Carr signed a three-year contract extension with the Raiders in April, a deal that includes a no-trade clause.

Houston Astros ace Justin Verlander added to his already convincing case for the American League Cy Young Award as he pitched six innings without allowing a hit in his side's 4-2 win against the Minnesota Twins on Tuesday.

Verlander, 39, is almost guaranteed to finish top-five in voting for best pitcher in the league for the ninth time in his career, and he showed why against the Twins as he struck out 10 while also allowing no walks.

He was pulled after six innings and 91 pitches with a no-hitter intact, before former Astros player Carlos Correa broke it up as he collected a hit from the very first pitch thrown by reliever Ryne Stanek.

Despite some late struggles by Astros bullpen arm Hector Neris, allowing a pair of runs in the ninth inning, the early offense highlighted by Alex Bregman's two-run home run was enough to get the job done.

Mauricio Dubon and Trey Mancini drove in a run each for the Astros, while rookie Jeremy Pena collected a couple of hits and Bregman went three-for-four.

With this performance, Verlander now leads the majors in wins (16-3), ERA (1.87) and walks-plus-hits-per-inning, or WHIP (0.85).

The win moves the Astros to 79-45, giving them a three-game buffer over the Yankees for the best record in the AL.

Yankees break streak of six consecutive series losses

The New York Yankees have finally rediscovered some form after a miserable month, winning their two-game series against local rivals the New York Mets as Frankie Montas pitched his best game in pinstripes in the 4-2 victory.

Montas, who arrived in a trade from the Oakland Athletics at the deadline, pitched five-and-two-thirds innings while giving up two runs from six hits and a walk after struggling in his first few starts in a Yankees uniform.

After four scoreless innings to open the game, Aaron Judge put the first run on the board with his league-leading 48th home run of the season, launching a 453-foot bomb. He now has 14 more home runs than second-placed Kyle Schwarber (34) from the Philadelphia Phillies.

Phillies win on a walk-off

The Philadelphia Phillies blew their lead in the ninth inning against the Cincinnati Reds, but it only set up a thrilling 7-6 walk-off win for the home fans.

Leading 5-4 heading into the final frame, closing pitcher Brad Hand was not able to finish off the job, as a fielding error and an infield single allowed two runners on base, who were both driven in by a pinch-hit RBI triple to T.J. Friedl.

In response, a lead-off walk to Jean Segura led to the tying run as Bryson Stott's RBI double made it 6-6, before pinch-hitter Nick Maton was the hero with a walk-off base hit.

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.

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."

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."

Oleksandr Usyk's promoter Alex Krassyuk has said a much-anticipated fight with Tyson Fury for all four of the world heavyweight titles is "in the making".

Usyk was a split-decision victor in his rematch against Anthony Joshua on Saturday in Jeddah, retaining the WBA, IBF and WBO belts that he took off the same opponent at the Tottenham Hotspur Stadium last year.

It means that the Ukrainian would now just need the WBC belt to make him only the second fighter in the four-belt era behind Claressa Shields to become undisputed in two different weight classes, having already held all four titles in the cruiserweight division.

That WBC belt belongs to Fury, who has not been in the ring since April when he defended his strap by stopping Dillian Whyte with a brutal uppercut in the sixth round at Wembley.

Fury has since claimed to be retired, but it appears that he could be tempted back into the ring to face Usyk and crown an undisputed champion in the heavyweight division, after telling his Instagram followers he would "annihilate" both Usyk and Joshua following the conclusion of their rematch.

And Usyk's promoter Krassyuk is confident the fight between the two undefeated titleholders will happen, telling Sky Sports on Tuesday: "It's in the making."

Speaking on Monday, meanwhile, Fury's co-promoter Frank Warren also indicated he is confident of the Briton getting in the ring with Usyk.

"[Fury] and Usyk would be a really good fight," Warren told BBC Radio 5 Live. "It's a fight that I think will be made because both teams would like to see that happen.

"Usyk said after the fight that it's the only fight he's interested in, and it's certainly the same case with Tyson. It's just a matter of where it will generate the most income because it's a unique fight, a historic fight."

Defending champion Primoz Roglic roared to the top of the Vuelta a Espana standings with a first stage win of this year's competition on day four in the Basque Country.

With the race resuming on Tuesday after a break to transfer from the Netherlands, the Slovenian moved up from third to take the red jersey with victory from Vitoria-Gasteiz to Laguardia.

Despite no other team members making the top 10 for the day, Roglic was ably supported by his fellow Team Jumbo–Visma riders, who helped him command the final uphill sprint to take victory.

After back-to-back stage wins for Ireland's Sam Bennett, it means Roglic has now reinforced his title defence, dethroning team-mate Edoardo Affini at the top.

Roglic edged Mads Pedersen, whose strong Vuelta continues apace with his third consecutive second-place finish, moving him up to ninth in the General Classification and second in points.

The former's team-mate Sepp Kuss lies second, 13 seconds off the overall lead, though the rest of their fellow Jumbo-Visma riders have slipped down the ranks ahead of Wednesday's leg from Irun to Bilbao.

Roglic happy to build early advantage

For the first time this year, Roglic has built a double-digit lead, and says he is happy to take the early advantage.

"It's really just the beginning of La Vuelta but it's always better to be 10 seconds ahead rather than behind," he stated.

"It was already a hard pace the whole day, with a super fast and hard stage. The finale was an opportunity to fight for the stage win. I had the legs so I gave it a go."
