Lewis Hamilton acknowledged he felt "emotional" and "surreal" after Kimi Antonelli was announced as his Mercedes replacement for the 2025 Formula 1 season.

The 18-year-old will join George Russell on the grid next year after a signing a one-year contract to fill the void left by Hamilton, who agreed a move to Ferrari at the start of the year.

Antonelli will become the third youngest F1 driver of all-time when he makes his competitive debut at the season-opener in Australia next March at 18 years and 203 days old, with only Max Verstappen and Lance Stroll younger in their first starts.

Hamilton had long been aware of the impending announcement, but admitted the reality of the situation still feels strange.

"I've known for ages, but I knew it would be announced [on Saturday]," he said. "I definitely woke up, and it was very surreal, just to have it officially confirmed my seat is going and that I've held onto it for so long," Hamilton said.

"I was quite emotional [on Saturday morning], but really happy for Kimi and for this team. I know Kimi is going to do a great job."

Hamilton will start this weekend's Italian Grand Prix sixth on the grid, while he also occupies sixth place in the Drivers' Championship having won the British Grand Prix and finished second at the Belgian Grand Prix this term.

And the seven-time world champion says he has felt a great deal of emotion heading into every race during the campaign.

"It's been there all year. Every single race, we have turned up," he added. "I love my team so much, and we have been through a hell of a lot together.

"So, it will be emotional every single race, because every race we do is the last time at that particular race and, every race, we get closer and closer to the last time I'll be in a Mercedes, and that is tough, it's definitely going to be tough.

"My focus now is to try and do the best job I can for the team and finish on a high."

Nico Williams remains happy at Athletic Bilbao for now but is unsure what his long-term future holds, saying: "God knows what will happen." 

Williams reportedly attracted interest from Barcelona and Arsenal during the recent transfer window, having enjoyed a terrific campaign as Spain won Euro 2024.

The winger played six of La Roja's seven games in Germany, scoring twice and laying on one assist. 

Only fellow Spain wideman Lamine Yamal (19) bettered his 13 chances created at the tournament, while he ranked second for successful dribbles (13) to Dani Olmo (14).

Williams has three years remaining on his contract with Athletic but that deal contains a €55million release clause, yet no club activated it before the window closed on Friday.

Speaking to DAZN after Saturday's 1-0 loss to Atletico Madrid in LaLiga, the 22-year-old insisted he remains content in the Basque Country.

"There were approaches from many clubs. I did well at the Euros and that's a great showcase," he said.

"I had many clubs to choose from but my heart is with Athletic. I'm happy here, I'm very happy here. God knows what will happen in the future."

Athletic have four points from as many matches in LaLiga this season, having also beaten Valencia, drawn with Getafe and lost to Barcelona.

Scottie Scheffler is in the driving seat as he targets a first FedEx Cup title, taking a five-shot lead into the final day at the Tour Championship.

The world number one made a slow start on Saturday but recovered to finish strongly with four birdies on the final five holes to maintain his lead, as he carded 66, moving his total to 26-under.

Scheffler is aiming to win his seventh PGA Tour event of the season at East Lake, with Collin Morikawa closest to him in second having carded a 67 in the third round.

"I've had my chances here to win some tournaments, and I'll have no better opportunity than Sunday," said Scheffler.

"I've been mentally at my best this year, and I'm looking forward to doing more of that in the last round."

Morikawa played himself into contention on Friday and was able to keep the pace with birdies on three of the last four holes on Saturday, while Xander Schaffuele slipped down to fourth, 10 shots off the top, with Sahith Theegala above him on 17-under.

After Morikawa's strong finish on Saturday, he remains hopeful that he will get a stroke of luck on Sunday to pip his compatriot to the title.

"It's going to be very hard, but I believe in myself that I can do it," Morikawa said.

"Five shots is a lot, but two-shot swings happen. I think I've seen a couple over the past few days.

"I've just got to play my game. I've got to go low. I've got 18 holes left in the season - I'm going to put everything I have into these next 24 hours."

Jadon Sancho wants to "bring excitement" to "iconic" Chelsea, and is looking to emulate idols Frank Lampard and Didier Drogba following his Deadline Day move from Manchester United.

The winger joined the Blues on a season-long loan deal which, according to widespread reports, includes an obligation to buy for between £20million and £25million.

That means Sancho would not be returning to Old Trafford, where he found first-team opportunities limited after a public falling out with head coach Erik ten Hag.

The 24-year-old, who made 83 appearances for United, spent the second half of last season on loan with former club Borussia Dortmund, helping the Bundesliga side reach their third Champions League final along the way.

Sancho appeared from the bench in the Red Devils' Community Shield defeat against Manchester City, but was not included in the matchday squad for their opening two Premier League games of the new season.

And he is excited by the prospect of a fresh start under Enzo Maresca, whose vision at Stamford Bridge proved too difficult for him to turn down. 

"I think it's the manager who really drew me to the project," Sancho, who will wear the number 19 shirt, told Chelsea's official website. 

"He spoke to me on the phone about this project and what he was building here, and for a young player like myself it's exciting, and I can't wait to get started.

"I enjoy his style of play. When [the wingers] get on the ball, he loves them to go one versus one and be direct. We play a lot of one-twos with the 10s and the striker combination plays. It's very attractive.

"I'm a skilful player and I want to bring excitement to the Bridge. Hopefully, it will turn out well.

"Chelsea is iconic. My idols growing up were Didier Drogba and Frank Lampard, and now I have the opportunity to play for this club like them. It's a great feeling."

Borussia Dortmund coach Nuri Sahin demanded improvements after watching his side play out a goalless draw with Werder Bremen in the Bundesliga on Saturday. 

BVB produced a meek attacking performance at the Weserstadion, with a 20-yard effort from substitute Karim Adeyemi representing their best sight of goal in the second half.

They attempted nine shots totalling just 0.63 expected goals (xG) overall, managing just 14 touches in the area to their hosts' 22.

To make matters worse, Dortmund saw centre-back Nico Schlotterbeck sent off for a second bookable offence in the 73rd minute and had to dig in for their point, leaving Sahin frustrated.

"As Borussia Dortmund, we have to perform differently, even if the team has undergone changes and has a new coach," Sahin told reporters. 

"It would be a very cheap excuse to say it is because of the transfer window. We have worked very well in the market. Still, we are expected to play better."

Dortmund have four points from their first two games of the Bundesliga season and host Heidenheim next time out on September 13, before facing Club Brugge in their Champions League opener five days later.

Joe Schmidt admitted he was on edge before Australia ended their eight-match Rugby Championship losing streak with a last-gasp 20-19 win over Argentina.

Ben Donaldson slotted over from close range with the last play of the game, much to the Pumas' frustration when the referee blew the full whistle.

Argentina held healthy leads twice, going 10-0 and 16-7 up. Jake Gordon and Rob Valetini crossed for Australia before Noah Lolesio's three kicks left the game on a knife edge before Donaldson sealed the win.

It is the first time the Wallabies have won in the competition since beating South Africa in 2022, and Schmidt was overjoyed that they were able to get the result over the line.

"It was heart in mouth," said Schmidt. "I'm really delighted for the boys, they found a way to win. I'm just really proud.

"We made a few things hard for ourselves, giving them a big start at home, a big crowd and difficult conditions.

"We put ourselves straight back under pressure by dropping restarts, but we fought, scored tries and created some other chances that would have been great.

"It'll be back to the drawing board a little bit, but I think we might even enjoy this one, just because we really had to fight to get it."

Argentina host Australia again in Sante Fe next week, while South Africa and New Zealand will meet in Cape Town in round four. 

Daniil Medvedev restored order by beating Flavio Cobolli in the US Open evening session, avoiding the same fates as former champions Novak Djokovic and Carlos Alcaraz.

The Russian, who is now the only former champion remaining in the men's field at Flushing Meadows, won 6-3 6-4 6-3 in two hours and 18 minutes.

Though Cobolli fought well, getting the first break in the match early on and valiantly defending set point six times in the first two sets, he could not stage another upset.

Medvedev struck 33 winners as he asserted his dominance and will meet Nuno Borges in the fourth round in New York.

"I said it before the match that for me the upsets don't really matter," Medvedev said.

"The only thing [is when] the conditions are a bit tricky, the favourites maybe have less margin than the other guys. Just have to be more cautious.

"It was a tough match. It was just a little bit up and down, and at one moment I started playing much better on my serve than on his.

"If I play good tennis I can win the whole thing. If I don't play good, I can lose against anyone."

Data Debrief: No upsets here

With two of the favourites for the title already out of the race, Medvedev will feel good about his chances of winning a second US Open title.

This victory was his 138th combined match win on hard court (grand slams and ATP Masters 1000 events), equalling Roger Federer for the second-most of any player on the surface in the past decade, trailing only Novak Djokovic (227). 

Medvedev is into the fourth round for the 11th time in the men's singles event at grand slams on hard court - he is the only Russian in the Open era to reach this stage 10+ times. 

Antonio Conte was displeased with the transfer market deadline due to potential injury risks after their 2-1 win over Parma.

Debutant Romelu Lukaku and midfielder Andre Zambo Anguissa scored stoppage-time goals to earn the Italian his second victory as Napoli head coach, and provisionally move fourth in the standings.

However, he was concerned about not having squad depth while dealing with last-minute changes made to his team due to the transfer window closing on Friday, leaving him hoping his players can remain fit.

"We take these three points knowing full well that we have to work after this absurdity of the transfer market," Conte told reporters.

"Coaches have to train players who are going to leave and wait for players we've never worked with and don't know in what condition they'll be when they arrive.

"We had zero midfielders on the bench today, as yesterday [Gennaro] Iaccarino and [Coli] Saco went on loan. We had to pray that nothing happened to [Stanislav] Lobotka and Anguissa.

"I hope that things can change in the future, seeing as everyone is ready to change formats and rules."

Conte added he was pleased with Napoli's transfer window, as they added Scott McTominay and Billy Gilmour to their ranks on Friday, despite the failure of Victor Osimhen's move to Saudi Pro League side Al-Ahli.

"We did not just bring in players to build on an existing team but to fill certain empty slots, and I am happy with the work done by the club," he said.

"If we had been able to sell Osimhen, it would've been an even better situation, but what happened cannot be changed, and we move on."

Iga Swiatek cruised into the fourth round of the US Open, crediting a chat with Serena Williams for her straight-sets win over Anastasia Pavlyuchenkova.

The world number one prevailed 6-4 6-2, without facing a break point in Arthur Ashe Stadium on Saturday.

Swiatek needed just 95 minutes to get into the next round, setting up a meeting with Liudmila Samsonova.

A four-game winning streak in the second set put the game beyond doubt, earning her a third straight-sets victory of the tournament so far.

"It was nice that Serena [Williams] approached me [in the players' gym], because I wouldn't, for sure, find courage to do that," Swiatek said.

"Even though we met before and for a couple of years we have been on the same sides and on tour together, she's still star-striking for me.

"It inspired me, and it gave me a positive kick.

"It's not like my tennis is perfect, but it is weird because I have been number one and winning tournaments, I feel I need to work on some stuff."

Data Debrief: Total dominance

Swiatek, who won at Flushing Meadows in 2022, is into the fourth round at a grand slam for just the second time this year, having failed to reach it at the Australian Open and Wimbledon.

It is the 16th time she has reached that stage in her 23rd main draw appearance - only Coco Gauff has also reached the fourth round in over half of her main draws at grand slams among active players.

The Pole looks to be in fine form though, with this victory lifting her winning percentage to 82.8% (82-17) in women's singles matches at grand slam events - she is now up to 11th on the all-time list in the Open Era, surpassing Martina Hingis.

Paulo Fonseca was quick to dismiss talk of any tension with Rafael Leao and Theo Hernandez, who both appeared to snub him shortly after coming off the bench.

The pair came off the bench to help earn a 2-2 draw with Lazio on Saturday, being brought on in a quadruple change by Fonseca after being left out of the starting line-up. 

Milan were losing 2-1 at the time of their introduction, and they immediately turned things around, with Hernandez and debutant Tammy Abraham, another substitute, involved in Leao's equaliser.

Minutes later, the game stopped for a cooling break, with both managers using the opportunity to instruct their players, but both Leao and Hernandez remained on the far side of the pitch, taking no part in the team talk.

"The situation with Theo and Leao, there is no problem and I think Theo has already explained," Fonseca told DAZN.

"We don't need to create any problems. This week I spoke with the players and they accepted my decision. There is no problem, I was concentrated, and I didn't see that they weren't there."

Hernandez had already given his reasons immediately after the game.

"We had been on for two minutes, we didn't need the cooling break," Hernandez said.

"It was nothing against the team and the coach. Then people talk, say things that aren't true. Rafa and I are always with the team to help, and that is the important thing."

Milan are still without a league win this season after three games, but Fonseca says he saw a decent performance in the opening half, giving him something to work on.

"We had a good first half. We always managed the game well with the ball. When you control the game like this, we have to have more moments to become dangerous, but it's something we have to work on," Fonseca told Milan TV.

"We must always have the courage we had in the first half because we did good things. If we had won the other two games, this could have been a good result, but it is not so. But we have to start from today's first half."

Shohei Ohtani, Mookie Betts and Freddie Freeman began the game with consecutive home runs, an unprecedented feat in Los Angeles Dodgers' history, and the National League leaders scored twice in the ninth inning to come through with an 8-6 victory over the rival Arizona Diamondbacks on Saturday.

Tommy Edman's two-run single in the top of the ninth snapped a 6-6 tie and helped Los Angeles expand its lead over Arizona and the San Diego Padres to six games in the division standings.

Ohtani added a sacrifice fly in addition to his NL-leading 44th homer of the season, which came on Arizona starter Merrill Kelly's eighth pitch of the night. Freeman finished 3 for 5 and also knocked in two runs to lead a 16-hit attack which propelled the Dodgers to a fourth straight victory and 10th in 12 games.

Betts followed Ohtani's game-opening blast with a shot over the left field wall, and Freeman connected on Kelly's very next pitch to give Los Angeles a quick 3-0 lead and mark the first time in the franchise's 141-year history it has started a game with three consecutive home runs.

The Diamondbacks answered with four runs in the bottom of the first, however, with Corbin Carroll beginning the rally with a lead-off inside-the-park homer off Gavin Stone.

Jake McCarthy and Joc Pederson then singled before Lourdes Gurriel drove in both with a double to tie the contest. Gurriel later scored on Eugenio Suarez's sac fly for a 4–3 Diamondbacks' advantage.

The Dodgers went back ahead in the second, though. After loading the bases on singles by Max Muncy and Miguel Rojas and a fielding error by Kelly, Ohtani plated Muncy with a sac fly and Freeman got Rojas home with a single for a 5-4 edge.

Gurriel's solo homer in the third knotted the score again, but the Dodgers retook the lead when Gavin Lux doubled in the fifth and crossed the plate on Muncy's single.

Arizona pulled back even by manufacturing a run in the seventh. Luis Guillorme drew a walk before advancing to third on a sacrifice and a wild pitch by reliever Brent Honeywell, then came home on Carroll's sacrifice fly.

It remained a 6-6 game into the ninth, which Will Smith and Lux opened with singles off Ryan Thompson (7-4) before both Dodger runners were moved up a base on a bunt. Two batters later, Edman delivered a two-out single off Justin Martinez to bring home each.

Evan Phillips then retired the side in order in the bottom of the ninth to give Ben Casparius a win in his MLB debut after the rookie threw a scoreless eighth inning.

Phillies' Wheeler dominates Braves for 100th win

Zack Wheeler earned his 100th career win with seven superb innings as the Philadelphia Phillies extended their lead atop the NL East with a 3-0 victory over the Atlanta Braves.

Wheeler (13-6) yielded just four singles and struck out seven to put the Phillies in position for a sixth win in eight games. Jeff Hoffman and Carlos Estevez finished off the shutout with an inning each as Philadelphia increased its margin over the second-place Braves to six games in the division standings.

Edmundo Sosa knocked in two runs for the Phillies on a double and a homer, a solo shot off Max Fried in the third inning that broke a scoreless tie.

Trea Turner made it 2-0 with a solo homer off Fried in the sixth. One inning later, Weston Wilson drew a walk in front of Sosa's RBI double that gave Wheeler more breathing room.

The Phillies nearly had another home run after Austin Hays drove a pitch deep to center field to start the bottom of the seventh, but Atlanta's Michael Harris climbed the wall to make a leaping catch and prevent the ball from landing in the Philadelphia bullpen.

Fried (8-8) allowed all three Philadelphia runs while permitting five hits and four walks in seven innings.

Atlanta has now lost two of the first three matchups of this key four-game set after entering the series having won nine of its previous 11 games.

Kukuchi fans 12 as Astros continue Royals' struggles

Yusei Kikuchi racked up 12 strikeouts over seven outstanding innings to lead the Houston Astros to a 5-2 win over the suddenly slumping Kansas City Royals in a matchup of American League playoff contenders.

Kikuchi (7-9) allowed just one run on five hits to improve to 3-0 with a 2.57 ERA in six starts since being acquired by the Astros from the Toronto Blue Jays in late July.

The left-hander duelled with Kansas City starter Cole Ragans through 5 1/2 scoreless innings before the Astros broke out with five runs in the bottom of the sixth.

Ragans was cruising along before giving up a single to Ben Gamel to begin the big inning. He then hit Jose Altuve with a pitch and walked Yordan Alvarez as Houston loaded the bases with none out.

Yainer Diaz then delivered a two-run single to break the scoreless tie, and Jeremy Pena followed with a triple to knock in two more runs for a 4-0 lead. Pena scored the Astros' final run on a wild pitch thrown by reliever Steven Cruz.

Pena finished 2 for 4 in Houston's fourth consecutive victory, which moved the Astros five games clear of second-place Seattle in the AL West after the Mariners lost to the Los Angeles Angels on Saturday.

The Royals finally got on the board when Freddy Fermin singled in the seventh, advanced to third on MJ Melendez's base hit and scored on Nick Loftin's fielder's choice groundout.

Bobby Witt's 29th homer of the season got Kansas City within 5-2 in the eighth, but Ryan Pressly kept the Royals scoreless in the ninth to record his third save of the season.

Kansas City has now dropped four straight following a stretch of 10 wins in 13 games.

Ragans (10-9) struck out 10 in five-plus innings but was charged with five runs despite permitting just four hits.

Barcelona forward Raphinha believes the team have laid down a statement of their intent by starting the season with four straight wins in LaLiga.

Raphinha scored the first hat-trick of his career and also delivered two assists on Saturday, as Barca crushed Real Valladolid 7-0 at Camp Nou.

Hansi Flick's side already possess a four-point cushion at the top of the table after also recording victories over Valencia, Athletic Bilbao and Rayo Vallecano.

Raphinha believes their results have demonstrated the club got things right in the transfer market, telling Movistar: "Today's game has shown that there is no need for anyone else to come. We are very happy because of that.

"We are in very good shape. The team is working hard. Today's result shows what we are working for. 

"We saw that the coach was on the sidelines asking for more goals and that's our mentality.

"We are hungry and want to score as many goals as we can. When we are dominant like we have been, the best way to respect our rivals is not taking the foot off the gas."

Raphinha was one of the players who faced criticism during Barca's trophyless 2023-24 campaign and was rumoured to be on his way out ahead of the new season.

The Blaugrana again battled financial restrictions throughout the window, allowing Ilkay Gundogan to leave in order to secure the registration of new arrival Dani Olmo.

With his future now certain, Raphinha is keen to nail down a starting spot and contribute on a regular basis.

"I don't know if today's was my best game, but it's certainly among my best. I will try to play even better and as much as I can," the Brazilian said.

"I'm very happy to be able to help the team. I feel good. I knew that this season would be very important for me. I'm looking for my best version to help my team-mates and be more confident."
