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."

Rafael Leao came off the bench to earn Milan a 2-2 draw with Lazio at the Stadio Olimpico on Saturday, but Paulo Fonseca's side are still without a Serie A win this season.

Milan were in front at the break through Strahinja Pavlovic's eighth-minute goal, the Serbian rising highest to power home a header from Christian Pulisic's corner.

However, Lazio hit back in the second half with Valentin Castellanos and Boulaye Dia scoring in quick succession.

Nuno Tavares' first-time ball into the centre was met by the unmarked Castellanos to level in the 62nd minute, then Dia tapped another Tavares cutback home to put the Biancocelesti ahead four minutes later.

Fonseca reacted by sending on four substitutes, and those changes had a swift impact as three of them combined for the leveller. 

Theo Hernandez – who joined Leao in being dropped from the start – picked out Tammy Abraham, and his lay-off allowed Leao to escape Tavares to fire past Ivan Provedel.

The game was preceded by an emotional tribute to the man who led Lazio to their last league title, Sven-Goran Eriksson, who died at the age of 76 on Monday.

A Lazio shirt bearing the Swede's name was displayed on the home bench, while a banner held up by the home fans read: "You brought us to the top of the world... Have a good trip Mr. Sven."

Data Debrief: Milan's slow start continues

New Milan boss Fonseca is already under pressure after overseeing a return of two points from his first three league games at the helm.

It is the first time the Rossoneri have drawn two of their opening three matches in a Serie A season since 2011-12, when they also drew two and lost one, 

They went on to finish second that season, just four points adrift of champions Juventus. If a title challenge is to take place this term, rapid improvements are needed. 

Romelu Lukaku and Andre-Frank Zambo Anguissa scored in second-half stoppage time as Napoli fought back for a thrilling 2-1 victory over Parma in Serie A.

Newly promoted Parma, who stunned Milan last week, looked set to claim a second surprise win in as many games when Ange-Yoan Bonny won and converted a 19th-minute penalty.

The momentum of the game changed, however, when Parma goalkeeper Zion Suzuki was shown his second yellow card for a foul on David Neres with 15 minutes of the 90 remaining.

With no further substitutions available to the visitors, defender Enrico Del Prato took over in goal and went close to getting his team over the line with a clean sheet intact.

However, new signing Lukaku came off the bench to equalise for Napoli in the second minute of stoppage time, shortly after the Partenopei had seen a penalty overturned following a VAR review.

There was more drama to come at the death as Anguissa headed home in the sixth minute of stoppage time, though Napoli also had to survive one last scare as  Pontus Almqvist was denied by Alex Meret at the other end.

Data Debrief: Flying start for Lukaku

Just as Napoli's hopes seemed to be slipping away, up stepped debutant Lukaku to level with a low strike, setting the stage for the most remarkable of comeback victories.

Across the last five Serie A campaigns, Lukaku has 29 goals in 48 home games for Inter, Roma and Napoli. That is the fewest home games required by any player to net over 25 goals in the competition during that span.

Parma, meanwhile, were left to rue the sending-off of Suzuki, who became their first goalkeeper to see red in Serie A since Antonio Mirante against Sassuolo, back in March 2015.

South Africa captain Siya Kolisi warned his team the job is far from done despite them rallying for a thrilling victory over New Zealand in the Rugby Championship on Saturday.

The Springboks secured a 31-27 win over the All Blacks at Ellis Park, coming from behind with two late tries from Sacha Feinberg-Mngomezulu and Grant Williams.

The victory hauled South Africa onto 14 points in the Championship standings as they bid to end New Zealand's four-year stranglehold on the title, but Kolisi says there is still work to be done.

Addressing the capacity crowd in his post-match interview, Kolisi said: "We play for a lot but you people are our number one motivation. 

"We appreciate you every single day. Please don't stop. When times are tough, please keep supporting us. We cannot do it without you.

"We respect the All Blacks. No matter what people say about them, when they need to turn up, they turn up. We believed in ourselves, we didn't panic, and we did what we wanted.

"They were catching us on the exit. After the first try in the second half, we picked it up. I'm really proud of the boys but the job is not done."

All Blacks captain Scott Barrett, meanwhile, was proud of his team-mates' efforts but admitted they had just fallen short of putting together a complete performance.

"Well done to the Springboks, it showed the class team they are," he said. "We weren't quite good enough. We were good for 62 minutes and it's an 80-minute game.

"There were two key moments after kick-offs where we couldn't quite get out of our half and they punished us. It was a huge effort, we're certainly proud, but it was just not quite to be.

"We'll regroup pretty quickly. Some guys have played here for the first time. It's intense and we'll have to be better next week."

South Africa host New Zealand again in Cape Town next week, while Australia go to Argentina for their round-three matchup. 

Jannik Sinner beat Australia's Christopher O'Connell in straight sets to reach the fourth round of the US Open on Saturday, avoiding a similar fate to Carlos Alcaraz and Novak Djokovic.

The men's draw at Flushing Meadows has been blown wide open by early exits for Alcaraz and Djokovic, but the top seed remains in the hunt after a composed performance.

He reached the fourth round for a fourth consecutive year with a routine 6-1 6-4 6-2 victory, setting the tone with several huge groundstrokes in the opening set.

O'Connell never looked likely to fight back as Sinner smashed 46 winners in a ruthless performance, wrapping up his win in one hour and 56 minutes.

The Australian Open champion will face either Tommy Paul or Gabriel Diallo for a place in the last eight, and he was relieved to survive an opening week full of surprises.

"Everything can happen in this sport, so I try to stay on my side of the net and I'm trying to take the tournament day by day," Sinner said in his on-court interview after the win. 

"Each opponent is a very tough challenge and [I am] also enjoying every moment on the court. There have been already a couple of upsets, so let's see what's coming.

"But I'm very happy to still be here and hopefully I can play as many matches as possible. But as I said, we go day by day and then we'll see how it goes."

Data Debrief: Sinner heating up

Sinner lost his first set of the tournament to Mackenzie McDonald but has been largely untouchable since then.

He has only lost 18 games across his last nine sets of tennis, an average of two per set.

The Italian's winning streak now stands at seven straight matches, meanwhile, following his triumphant Cincinnati Open run.

Thomas Frank heaped praise on Brentford's pressing following their 3-1 victory over Southampton on Saturday.

Bryan Mbeumo scored twice from Brentford's forwards forcing the Southampton backline into errors as the Bees earned their second Premier League win of the season.

This did not go unnoticed by Frank, who believes his side rank as one of the best in the league when it comes to that specific aspect.

He told BBC Sport: "They made errors because we pressed them unbelievably well. I think we are one of the best teams to do the high pressure in the Premier League.

"The players are so committed and that is the reason why we capitalised on errors from Southampton.”

Despite the departure of Ivan Toney to Al-Ahli, Frank does not think their style of play will have to be restructured too much, with both Mbuemo and Yoane Wissa enjoying productive starts to the season in his absence.

Frank said: “Ivan is a fantastic player, I'd love to have him in the team but he has his own journey and is going elsewhere.

"Our style of play hasn't changed. Wissa and Ivan are different players but the style doesn't change.”

Southampton boss Russell Martin was frustrated with his side’s mistakes at crucial moments, believing their performance was far better than the scoreline suggested.

He said to the BBC: “We made two mistakes that we were punished for, which is frustrating and disappointing.

"I saw lots of good things to feel positive about. I feel a lot better this week than I did after the Nottingham Forest game.”
