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. 

Casper Ruud played twice on Saturday to win the Geneva Open, as he heads into Roland-Garros in fine form.

With his semi-final against Flavio Cobolli having been postponed on Friday due to rain, Ruud returned to the court to seal a 1-6 6-1 7-6 (7-4) victory.

The Norwegian was swiftly back in action in Switzerland, taking on Tomas Machac, who stunned Novak Djokovic on Friday, in the final.

And the world number seven made light work of Mahac, winning 7-5 6-3 to become the first three-time champion at the Geneva Open, which he also won in 2021 and 2022.

Ruud has now claimed an 11th ATP event title on clay since the start of the 2020 season.

He is the only player to win 10+ titles over that span on the surface, with Carlos Alcaraz (seven) the next best.

Tomas Machac upset Novak Djokovic as he captured the biggest win of his career to deny the Serbian a place in the Geneva Open final.

Machac reached his first ATP Tour final with a 6-4, 0-6, 6-1 victory on Friday following a hard-fought contest.

Djokovic had control of the first set, storming into a 4-1 lead, but Machac rallied to take the opening set.

After receiving a medical time-out before the second set, Djokovic superbly won the second set without dropping a single game but faded in the decider.

Djokovic won the opener in the third, but Machac came from behind to seal the win in two hours and seven minutes. He will face Casper Ruud or Flavio Cobolli in the final on Sunday. 

Data Debrief: Final still out of Djokovic's reach

Despite making a strong start to the Geneva Open, fitness problems seem to have caught up with Djokovic ahead of the French Open later this month. 

He lost his second career match despite having won a set with a 6-0 scoreline (after Sam Querrey in the Paris Masters in 2012), and has failed to make a final in 2024.
