World No 1 Jannik Sinner on Monday lifted his third ATP Masters trophy as the world number one beat Frances Tiafoe 7-6 (7/4), 6-2 to win the Cincinnati Open.

The Italian top seed warmed up for next week's US Open in style, biding his time in a hardfought first set before breaking the match open in the second.

Tiafoe, whose game faded after losing the first-set tiebreaker, still made an impression.

The American, who moves into the ranking top-20, saved three match points before Sinner claimed his 15th career title.

Cincinnati is the fifth trophy of 2024 for the 23-year-old Italian, who began the season with an Australian Open crown in Melbourne.

"I'm happy, this was a very difficult week," Sinner said."It was tough mentally but I tried to do my best.
