Jannik Sinner required physio treatment after the second set of his US Open 2025 semifinal against Felix Auger-Aliassime on Friday, sparking concern among fans.

“Hopefully not anything too serious,” fans said, while some viewers felt that he just took a break just because he was being outplayed by his opponent.

Sinner took a medical timeout because of a bothersome abdominal muscle.

After losing the second set, he took control of the match for a 6-1, 3-6, 6-3, 6-4 victory over Felix Auger-Aliassime moving closer to a second consecutive title at Flushing Meadows.

No one has repeated as the men’s champion in New York since Roger Federer took five trophies in a row from 2004-08.

“It’s great for the sport having rivalries, having hopefully great matches in front of us,” Sinner said. “I’m someone who loves these challenges, and I love to put myself in these positions and to see how it goes.”

Alcaraz beats Djokovic to reach US Open final

Second seed Carlos Alcaraz took down 24-times major winner Novak Djokovic 6-4 7-6(4) 6-2 with clinical precision to reach the U.S. Open final on Friday, prevailing in a blockbuster showdown that packed the house at Arthur Ashe Stadium. The match was billed as the hottest ticket in New York and lived up to the hype, with a scoreline that belied its intensity, as the 2022 champion Alcaraz soaked in deafening cheers on match point.

“It’s something that I’m working on, just the consistency on the matches, on the tournaments, on the year in general,” said Alcaraz, who won his fifth major title at Roland Garros this year and finished runner-up at Wimbledon.

“Just not having up-and-downs in the match. Just the level that I start the match, just wanted to keep that level really high during the whole match.”

The No. 1-seeded Sinner will now play against No. 2 Carlos Alcaraz on Sunday, making them the first men in tennis history to meet in three straight Grand Slam finals within a single season, according to the ATP.

“It’s a very special day,” Sinner said about Sunday’s matchup. “It’s a very amazing final again.”
