Jannik Sinner announces changes after losing US Open and No. 1 spot to Carlos Alcaraz

In front of nearly 25,000 fans, Carlos Alcaraz captured his second US Open title on Sunday, defeating Jannik Sinner in four sets in a commanding final. The Spaniard now owns six Grand Slam trophies and officially takes over as the new ATP world No. 1.

For Sinner, the loss ended his 65-week run atop the rankings. Speaking in his post-match press conference, the Italian praised Alcaraz’s all-around game and their growing rivalry.

“He’s a different player, with no obvious weaknesses like others have, and that makes him tough,” Sinner said. “We already have a bit of history, head-to-head battles, different situations. That makes it interesting”.

Sinner admitted his predictability was a key factor in the defeat and promised adjustments in his upcoming tournaments. “That’s his style—changing things, being unpredictable. It’s on me to make changes. I’ll work on it, even if it means losing some matches, because I need to get out of my comfort zone”.

The 23-year-old reflected positively on his season despite the loss, highlighting his four Grand Slam finals, two titles, and two runner-up finishes. Still, he vowed to evolve his game, particularly his serve, to return stronger.

“Small changes can make big differences,” Sinner added. “I know I’m a solid baseliner and a good ball striker, but I need to add more. Now I’m no longer No. 1, and that also changes what you chase. I’m motivated to keep working and play these kinds of matches again”.
