Alexander Zverev

In his previous six bouts with Stefanos Tsitsipas, the German has only come out on top once. Zverev changed that by defeating the Greek, 6-4, 7-6 (3), to win his first Acapulco title. This marks Zverev's 14th career ATP title and his first of the season.

The world No. 61 captured her second title of the season, becoming the first Russian woman to win St. Petersburg after countrywoman Margarita Gasparyan retired with a back injury while trailing 6-3, 2-1. Kasatkina is now 15-3 this season and is creeping closer to returning to the Top 50.

Aslan Karatsev

The incredible 2021 season continues to get better for the Russian. Karatsev picked up his very first ATP title in Dubai by serving Lloyd Harris a 6-3, 6-2 loss. He is now 15-2 this year with his only losses coming to major champions Novak Djokovic and Dominic Thiem. Not too bad, right?
