Ammon News - Jannik Sinner won the 21st title of his career by thrashing American teenager Learner Tien 6-2, 6-2 in the China Open final on Wednesday.

The Italian world number two lifted the trophy for the second time in Beijing, where he beat former US Open champion Daniil Medvedev in the final in 2023.

Sinner, a four-times Grand Slam winner, took over the 19-year-old American after Medvedev retired from their semi-final with what looked like cramp while trailing 7-5 5-7 0-4.

There were no signs of discomfort in his first meeting with Tien, however, as Sinner settled into the match with a break in the opening game and looked solid throughout to take the first set with a hold in the final game.

Tien, playing in his first final and bidding to become the youngest American ATP Tour champion since Andy Roddick in 2002, twice earned breakpoints in the second set but Sinner fended them off and built a 4-2 lead.

The 2023 champion then sealed the win to became the second man to claim multiple titles at the ATP 500 tournament after Novak Djokovic (2009-10, 2012-15).
