Jannik Sinner reassured fans following his US Open semi-final win against Felix Auger-Aliassime Friday evening that there is no reason for concern about his health. The Italian left the court to receive treatment on his stomach region after losing the second set.
“I just felt a small twitching after a serve when I served there in the second set on 4-3. After the treatment, was feeling much, much better,” Sinner said. “At some point I didn’t feel anything anymore. I was serving back to normal pace, so it was all good. Nothing to worry about.
“But I preferred to go off court because it’s on a different spot. So it’s all good.”
Despite being forced to leave the court and dropping his second set of the tournament, the No. 1 player in the PIF ATP Rankings stormed back for a four-set win, making his fifth consecutive major final.
Sinner has won three of the past four Slams and can make it four of five if he defeats rival Carlos Alcaraz in Sunday’s championship match. The Italian is trying to claim his fifth major trophy.
“Amazing stats. I would have never thought that I would make this when I turned pro, and now I find myself here, so it’s amazing,” Sinner said. “I think five straight Grand Slam finals, it’s something great. The consistency and putting myself there in the later stages of the biggest tournaments we have, it’s amazing.
“But in the same time, I know it’s in the back of my head, whatever I’m doing, but in the same time whatever is done is done. I’m here. I have a very important day Sunday, and then we’ll see.”
The defending champion knows he faces a stern test against Alcaraz, who leads their Lexus ATP Head2Head series 9-5. Sinner held three championship points against the 22-year-old in the Roland Garros final, but fell short. The Italian then earned revenge against Alcaraz in the Wimbledon final.
“I love these challenges. I love to put myself in these positions. He’s someone who pushed me to limit, which is great, because then you have the best feedback you can have as a player,” Sinner said. “We have faced each other quite a lot now lately, so things are getting a little bit different.
“Always when we step on court, we are aware of maybe more things, because him or me, we try to prepare the match tactically and in different ways. But sometimes it’s also nice to not play against him. It’s nice, but as I always said, it’s great for the sport having rivalries, having hopefully great matches in front of us.”
