Top seed Sinner, the first Italian man to reach a U.S. Open singles final, received medical attention beside the court during the gruelling straight-set win, while his opponent vomited three times in the New York heat.
“The physio (loosened) it up very fast on court, so after I felt OK in the beginning. Then, after, it went away by playing, which is good,” Sinner told reporters.
“Let’s see how it is tomorrow when it’s cold. It’s going to be a different feeling. Hopefully it’s nothing to concern about.”
The Australian Open champion, who faces American 12th seed Taylor Fritz in the final today, said he expected a difficult match, playing against a home favourite hoping to end the host nation’s 21-year men’s Grand Slam drought.
“We’re in New York playing against an American, so it’s going to be, for sure, the crowd a little bit more on their side. But it’s normal. It’s like when I play in Italy... so I’m going to accept that,” Sinner said.
