Alexander Zverev captured his fifth title of the season at the Vienna Open after defeating Frances Tiafoe 7-5 6-4 in Sunday's final.

The Olympic champion claimed more silverware in Vienna, having also triumphed in Madrid, Cincinnati and Acapulco in 2021.

The world number four, who claimed his 300th tour-level career win against Alex de Minaur earlier in the week, is now 25-2 since exiting the fourth round at Wimbledon in July.

Tiafoe was appearing in his first ATP 500 final having defeated Stefanos Tsitsipas, Diego Schwartzman and Jannik Sinner along the way.

The world number 49 stuck with Zverev during a tight opening set, in which breaks were exchanged early on.

However, the German broke again in game 12 to draw first blood, and went on to hit eight aces during the second set.

Tiafoe produced an inspired turnaround from 5-2 down in the second set of his semi-final victory over Sinner.

But there was to be no fairytale finish for the American, who was seeking a second ATP title and first since the 2018 Delray Beach Open.

Zverev subsequently held his nerve to move level with Casper Ruud on five titles for the season, the most on the ATP Tour this year.
