Aug 16 (Reuters) - Top seed and defending champion Jannik Sinner, playing on his 24th birthday, ended French qualifier Terence Atmane's dream run at the Cincinnati Open with a 7-6 (4) 6-2 win on Saturday to reach the final of the U.S. Open tune-up event.

Jannik Sinner and Carlos Alcaraz will clash in Sunday's Cincinnati Open final after the world's top two players won their respective semi-finals on Saturday. World No 1 Sinner and second-ranked Alcaraz will meet in a repeat of the French Open and Wimbledon finals earlier this summer.

ATP No. 1 Jannik Sinner is bidding to become the first back-to-back Cincinnati Open men's singles champion since Roger Federer.
