Jannik Sinner is currently trailing his rival Carlos Alcaraz with only 5 wins out of 15 encounters.
Jannik Sinner is participating in the ATP 500 China Open 2025 in Beijing, where he is the defending runner-up. Although his main rival Carlos Alcaraz is not competing here and has chosen to play in Tokyo (Japan Open), the high-profile rivalry between Sinner and Alcaraz continues to attract significant attention from fans and experts alike.
After his loss at the US Open—the last Grand Slam of the year—Sinner admitted that his serve was below standard and needs improvement to keep pace with Alcaraz. He confirmed he is willing to lose some matches while experimenting with new tactics, determined to become a more complete player.
"I will adjust a few aspects of my serve, even if they are minor details, they can make a big difference. I’m really looking forward to starting fresh in these matches. Now I’m the one chasing, everything has changed," Sinner shared at the press conference during this year’s China Open.
The Italian player revealed that his coaching team has thoroughly analyzed the US Open final and made several adjustments. "We are working on small changes. I might make more mistakes, but I believe everything will improve. It’s just a matter of time.", the world No. 2 stated.
Sinner’s determination quickly showed results. In his opening match at the China Open, he achieved a 77% first serve success rate, a stark contrast to the 48% during his loss to Alcaraz. Thanks to the improved serve, Sinner comfortably defeated the 2014 US Open champion Marin Cilic with identical set scores of 6-2.
"I tried to stay fully focused in the first round knowing things might not go as planned. I arrived early in Beijing to get used to the court conditions. Breaking Cilic early in both sets boosted my confidence.", the Italian player commented.
In the second round of this year’s China Open, Sinner will face Terence Atmane—who was a standout at last month’s Cincinnati Open with a fast and powerful playing style.
