Jannik Sinner is brushing aside any injury fears as he gears up for an electrifying US Open final against rival Carlos Alcaraz. After a hard-fought win over Felix Auger-Aliassime in the semi-finals, Sinner showed resilience despite a minor concern.

During a tense moment in the second set, Sinner experienced a "small twitching" in his stomach, prompting a brief medical timeout. The World No. 1 pointed to his abdomen before stepping off the court for treatment, raising alarms among fans and analysts alike.

However, the 24-year-old returned with vigor and reclaimed his signature serve, ultimately overcoming Auger-Aliassime in four sets. The relief was palpable as he clinched match point, marking his return to the US Open final for a highly anticipated rematch against Alcaraz.

"It's nothing serious," Sinner said confidently when questioned about the timeout. "I felt a minor issue, but after some treatment, I was back to my usual self. Sunday is going to be special—an amazing final to look forward to!"

Earlier, Sinner described the moment that triggered his concern. "It was just that small twitch during my serve at 4-3 in the second set. Thankfully, once I got the treatment, I felt considerably better and went back to serving like my normal self. Nothing to worry about!"

This final is monumental, as Sinner and Alcaraz will meet for a record third consecutive time in a Grand Slam final, a first in the Open era. Their previous battles took place at the French Open and Wimbledon this summer.

The stakes couldn’t be higher; not only is Sinner vying to defend his title, but the World No. 1 ranking is also up for grabs. Their last encounter at the US Open in 2022 was a gripping five-set thriller won by Alcaraz.

Sinner reflected on their budding rivalry, saying, "I feel like our journey began here. We've both evolved as players with different levels of confidence. It all comes down to who’s better prepared for this clash.”

With his victory over Alcaraz at Wimbledon, Sinner has now notched an impressive 27-match win streak at hard-court Grand Slams, making him a formidable opponent.

On the flip side, Alcaraz, eager for revenge, is hunting for his second US Open title and has the chance to reclaim the World No. 1 spot with a win. Having just triumphed over Novak Djokovic in the semi-finals, he’s fueled by determination and a desire for redemption.

This Sunday promises to be a showdown for the ages, as two of the sport’s brightest stars clash once more. Can Sinner fend off Alcaraz's quest for revenge, or will the Spaniard emerge victorious this time?
