Jannik Sinner survived an early scare in the US Open first round after overcoming Mackenzie McDonald on Tuesday.

The Italian managed a 2-6 6-2 6-1 6-2 victory over the world number 140, having looked well off the pace in the opening set.

McDonald's fellow American Alex Michelsen awaits in the second round for Sinner, who triumphed in his first major match since an independent tribunal cleared any wrongdoing from positive tests for banned substances.

The world number one may have been impacted by those ongoing off the court and was slow to get going, dropping his serve three times en route to a first-set concession.

Sinner held off seven break-point opportunities from the home favourite in that opener, and improved from then on, losing on his serve just once in the second set.

The 23-year-old never looked back from that second-set clincher, easing to victory in just under two-and-a-half hours.

Data Debrief: Super Sinner flying

Sinner, who won his maiden major trophy at the Australian Open in January, is now 49-5 for the season after an impressive 2024.

That run includes lifting a third ATP Masters 1000 crown in Cincinnati last week, where he overcame his next opponent Michelsen in the pair's only ATP Tour meeting to date.

Jay Stansfield was on target against former club Birmingham City as Fulham swept aside their League One hosts with a comprehensive 2-0 victory in the EFL Cup second round.

Marco Silva's side fell short against Liverpool in the semi-finals of this competition last season, but made another good start to the new cup campaign on Tuesday after easing to victory at St. Andrew's.

Raul Jimenez opened the scoring with a 10th-minute penalty, awarded for handball against Alex Cochrane, before Birmingham were undone by a familiar face just four minutes later.

Striker Stansfield spent last season on loan with the Blues and, owing to that spell, refused to celebrate after profiting from Joachim Andersen's long pass before finishing with a clinical edge.

Birmingham could find no second-half response as Fulham progressed into Wednesday's third-round draw, with the Cottagers' next task a trip to Ipswich Town in the Premier League on Saturday.

Data Debrief: Cup control for Cottagers

Fulham have progressed from 12 of their last 15 EFL Cup ties against sides from a lower division, including Tuesday's win and both such matches last term against East Anglian duo Norwich City and Ipswich.

This outcome was somewhat expected, considering Fulham have won their last six games in all competitions against Birmingham by an aggregate score of 16-3.

Birmingham, meanwhile, have lost at this stage in their last four attempts (2017-18, 2021-22, 2023-24 and this season).

Naomi Osaka secured a long-awaited victory over a top-10 opponent after dispatching Jelena Ostapenko at the US Open on Tuesday.

World number 88 Osaka scored a 6-3 6-2 victory against Ostapenko for her first top-10 win in four-and-a-half years.

Osaka has now won 23 of her 28 matches at the US Open, at an 82% win ratio, which only Bianca Andreescu (86%) can better among current players with 10 or more main-draw matches at the tournament.

The four-time major winner was reduced to tears after downing the 10th seed in New York.

"I was trying not to cry when I was walking out too," Osaka said in her on-court interview. "I remember last year I was watching Coco [Gauff] play and I so badly wanted to step on these courts again and I didn't know if I could.

"I didn't know athletically, physically if I was able to. Just to win this match and just to be in this atmosphere means so much to me, so thank you."

Osaka, who won 39 of her 50 service points and held her serve throughout, needed three match points to move into the second round.

"I mean it was stressful, she was hitting some really good shots and I just told myself like, keep going, keep fighting for every point and maybe you'll have an opportunity," she added. 

"Eventually I did but then I looked up and then I saw so many faces so I was like, woah."

The unseeded Karolina Muchova awaits on Thursday for the Japanese star after her first-round triumph.

Liverpool have confirmed the signing of Giorgi Mamardashvili from Valencia, with the goalkeeper immediately loaned back to Los Che for this season.

The Georgia international impressed at Euro 2024 with his country and has subsequently earned a move to Anfield, becoming the first major signing of Arne Slot's Liverpool tenure.

Mamardashvili will stay in Spain with Valencia for the remainder of the LaLiga campaign before moving to Merseyside ahead of the 2025-26 campaign.

Widespread reports suggest the Reds have agreed a €30million deal (£25m), including add-ons, to sign the 23-year-old, who will be expected to challenge Alisson for the starting spot in goal.

Mamardashvili's move comes off the back of an impressive European Championship showing, managing 21 saves during the three group-stage games, the joint-most of any goalkeeper in the tournament's history.

He has recorded 102 appearances for Valencia, keeping 31 clean sheets in all competitions and starting both of their fixtures so far this term against Barcelona and Celta Vigo.

Goalkeeping rival Alisson has two years and the option of a further year left on his Liverpool contract, but is expected to remain as the first-choice option, with Caoimhin Kelleher also among the Reds ranks.

Slot's side are said to be interested in Juventus' Federico Chiesa, too, before the transfer window closes on Friday in England.

Roma have signed Saud Abdulhamid from Saudi Pro League champions Al Hilal, the Serie A club announced on Tuesday.

Reports in Italy suggest the deal for the 25-year-old defender was worth €3million.

"Roma are pleased to announce the signing of Saud Abdulhamid on a permanent deal from Al Hilal," the club said in a short statement.

The Saudi Arabia international was a key player for Jorge Jesus' side last season, netting four times and providing nine assists in all competitions to help Al Hilal win a domestic treble.

Manchester City's Joao Cancelo joined Al Hilal to replace Abdulhamid, who will be the first Saudi Arabian player to compete in Serie A.

Iga Swiatek moved into the US Open second round after holding off a spirited Kamilla Rakhimova for a straight-sets win on Tuesday.

Lucky loser Rakhimova came close to forcing a decider, but the world number one rallied to win 6-4 7-6 (8-6) in just under two hours.

The early stages of the match suggested it would be a one-sided rout as Swiatek got two early breaks to race into a 4-0 lead, but Rakhimova clawed it back to 4-3 before the Pole dug in to take the set.

A similar story followed in the second set, though the world number 104 was unable to close out the victory after edging in front at 5-4, with Swiatek forcing a tie-break.

Swiatek then saved a triple set point from 6-3 down, winning the final five points to avoid an early upset and set up a meeting with either Daria Saville or Ena Shibahara in the next round.

Data Debrief: Swiatek tries her luck

It could have been a much different story for Swiatek had Rakhimova been able to hold her nerve in the tie-break, but as such, the 2022 winner stays in the tournament.

She is now the fifth-youngest player in the Open Era to win the first round in 20 consecutive women's singles grand slam events.

Meanwhile, only Serena Williams (93) and Venus Williams (94) have made 80 women's singles grand slam wins in fewer matches than Swiatek (97) this century.

Williams have replaced Logan Sargeant with Franco Colapinto for the last nine races of the 2024 Formula 1 season.

Sargeant was already set to leave Williams at the end of the season, with Ferrari's Carlos Sainz set to take his seat for 2025.

However, his second season in F1 has been cut short, following a huge crash in the final practice session at the Dutch Grand Prix on Saturday.

In 36 races, Sargeant earned one point for Williams, compared to team-mate Alex Albon, who scored 31 points during that period.

Colapinto will make his competitive debut at the Italian Grand Prix this weekend, having previously driven for Williams in practice at the British GP earlier this year.

"It is an honour to be making my Formula 1 debut with Williams – this is what dreams are made of," Colapinto said.

"The team has such amazing history and a mission to get back to the front, which I can't wait to be part of.

"Coming into F1 mid-season will be an enormous learning curve, but I am up for the challenge, and I'm fully focused on working as hard as I can with Alex and the team to make it a success."

Arsenal have announced the signing of Mikel Merino from Real Sociedad on a four-year contract.

The midfielder has joined in a deal worth up to £31.6million, with the option to extend his stay for an extra year.

Merino is returning to the Premier League, having signed for La Real from Newcastle United in 2018.

He made 242 appearances for the Spanish side in all competitions, scoring 27 goals and registering 30 assists.

Last season, he won 326 duels, the most of any player in the top five European Leagues, while his 197 recoveries in LaLiga were the most of any outfield player for La Real.

"Mikel is a player who will bring us huge quality with his experience and versatility," Mikel Arteta said of his new signing.

"He has played at the top of the game at both club and international level for a number of seasons now. Mikel will make our squad significantly stronger, with his technical ability, together with his strong and positive character and personality.

"As we all saw in the summer, Mikel is also a winner, with his strong performances throughout the Euros helping Spain win the tournament. We are delighted to welcome Mikel and his family to the club and can't wait to start working with him."

Merino is the fourth signing by Arsenal during this transfer window, after Tommy Setford, Riccardo Calafiori, and the permanent move for David Raya.

Jonny Bairstow must recapture his pre-injury form if he is to regain his place in the England white-ball set-up.

That is according to England's chief selector, Luke Wright, following the decision to leave Bairstow out of the squad to face Australia in a limited-overs series next month.

Bairstow has missed out on England's first white-ball series since the T20 World Cup, with fellow veteran campaigners Chris Jordan and Moeen Ali also left out.

But Wright says the door remains open for Bairstow, if the 34-year-old can play his way back into the form he showed before sustaining a broken leg while golfing in 2022.

"One of Jonny's great strengths is how much he wants to play," said Wright. "He's hugely disappointed.

"We just want him back to being one of the best players in the world. He had that horrific injury, and that’s been the message. Can we get you back to where you were pre-injury?

"He understands that. He doesn’t like it. One thing Jonny will do is fight back, and I hope he does and gets himself back in the team."

Wright is hoping the refreshing of England's squad in the wake of their T20 World Cup disappointment helps spur Jos Buttler's team on, with coach Matthew Mott having also left after that tournament.

"The one thing we don't lack in England is the amount of talent that's around," Wright said.

"More than anything, the character these young players show in taking the game on.

"What a great time to be in English cricket."

England's Test team, meanwhile, have made one alteration to the team that featured in the first match against Sri Lanka, ahead of the second contest of the series, with Olly Stone replacing the injured Mark Wood.

Former Juventus and Arsenal goalkeeper Wojciech Szczesny has announced his retirement from football.

He won 11 major trophies during his career in England and Italy, and earned 84 caps for Poland, playing in seven major tournaments for his country.

Szczesny agreed to mutually terminate his contract with Juventus earlier this month after a breakdown in negotiations over a move to Saudi Pro League club Al-Nassr.

The goalkeeper joined Arsenal as a 16-year-old in 2006, making 181 first-team appearances and winning two FA Cups in 2014 and 2015.

After spending two seasons on loan at Roma, he then joined Juventus in 2017, winning eight major trophies, including three Serie A titles.

Since making his Serie A debut, the Pole made the fifth most saves in the league (among goalkeepers to play at least 50 games), making 481, while he also had the fifth-best save percentage in that time – 72.55%.

Only two goalkeepers in Serie A bettered Szczesny's 200 league appearances since his debut, though he conceded considerably fewer goals (179) than both Andrea Consigli (411) and Lukasz Skorupski (301) during that time. 

In a post on Instagram, Szczesny announced his retirement, claiming his heart was no longer in the game.

"I left Warsaw, my hometown in June of 2006 to join Arsenal with one dream – to make a living out of football," he said. "Little did I know it would be a start of a journey of a lifetime. Little did I know that I would get to play for the biggest clubs in the world and represent my country 84 times.

"Little did I know that not only would I make a living out of the game, but the game would become my whole life. I didn't just realise my dreams; I've arrived where my imagination wouldn't even dare to take me.

"Everything that I have and everything that I am I owe to the beautiful game of football… But I also gave the game all I had. I gave the game 18 years of my life, every day, without excuses.

"Today, my body still feels ready for challenges, my heart is not there anymore. I feel that right now it is time to give all of my attention to my family. Therefore, I have decided to retire from professional football." 

Samuel Iling-Junior has joined Bologna on a season-long loan from Aston Villa.

The 20-year-old joined the Villans at the start of July as part of a double transfer from Juventus with Enzo Barrenechea for a combined £18.6million.

However, he has not featured in either of Villa's matchday squads since the start of the Premier League season, with Leon Bailey and Morgan Rogers preferred in the wide areas.

Iling-Junior made 27 appearances for Juventus in all competitions last season, scoring once and registering two assists, helping the club to win the Coppa Italia in May.

Bologna are yet to win this season in Serie A, drawing with Udinese and losing to Napoli, but are set to compete in the Champions League, having qualified for the tournament for the first time since 1964.
