Jannik Sinner won the China Open by beating American teenager Learner Tien 6-2, 6-2 in Wednesday's final to continue his preparations for the Shanghai Masters.

Sinner rebounded from his U.S. Open disappointment by winning his third title of the season -- his 21st altogether -- with a dominant performance against the 19-year-old Tien, the second-youngest player to reach the tournament's final.

"We will try to improve and push for more and let's see what the rest of the season looks like, but I am very happy," Sinner said from Beijing.

Sinner next goes to Shanghai, where he'll be the favourite after Carlos Alcaraz withdrew because of an ankle injury sustained in the first round of the Japan Open, which he won Tuesday.
