One day ahead of the US Open men’s final on Sunday, Jannik Sinner’s coach provided an injury update on the world No. 1.
The defending US Open champion sustained an abdominal injury during the second set of his semifinal with Felix Auger-Aliassime. The Canadian won the second set as Sinner received medical treatment. Sinner ended up winning in four sets and will face No. 2 Carlos Alcaraz in the final.
“He just had a little abdominal discomfort at one point, but after treatment with the physiotherapist, it went away,” Simone Vagnozzi, Sinner’s coach, Said Per Super Tennis (via Tennis Gazette.) “When he came back, he wasn’t sure how he was doing in the first few games, so he didn’t push. Then he started pushing, and his serve got better and better. I think he’s fine for Sunday.”

The injury impacted Sinner’s serve – he made just 53% of his first serves – and his team made suggestions on how he could change his motion.
“During the match, we recommended a few more kicks to start the rally with an advantage,” he said.
“Then the abdominal discomfort complicated the situation; he felt more pain when throwing the ball back.
“Maybe at a certain point, he played too much in the middle, and Auger-Aliassime was able to swing his forehand. It’s not easy to change heights against someone who serves and pushes so hard.”
The US Open final will mark the third straight major final featuring Sinner and Alcaraz.
Alcaraz holds a 9-5 career advantage, 3-2 in majors and 6-2 on hardcourts, including the Cincinnati final where Sinner retired with a virus.
Alcaraz is 7-3 in their last 10 meetings.
“Carlos can vary a lot; he can use different tactics, so you have to prepare as best you can and try to execute your plan,” Vagnozzi said.
“It will be a very difficult match against Carlos.”
