How the smooth-hitting American made the most of the pandemic break, and how he’s aiming for more now.

This past week saw a wave of U.S. tennis talent thrive on home soil throughout the country.

Meanwhile, Barbora Krejcikova made her Top 10 debut and Jannik Sinner cracked the Top 15.

After his win over Mackenzie McDonald at the Citi Open, Sinner has three ATP titles at 19. Even scarier, he has a lot of room to improve.

The American suffered a torn hamstring in 2019 and is in the midst of a career renaissance.

The American saved all five of his break points en route to a solid 6-4, 6-4, victory.

The Ukrainian began building his channel last spring during quarantine.

Winless in two previous meetings with his friend, McDonald looks for a positive start to the North American hard court swing.

“What’s happening today? An hour and half yesterday, the chair of the ATP [expletive] screaming at me in a player meeting, for trying to unite the players,” the Canadian told chair umpire Arnaud Gabas Wednesday during his loss to Mackenzie McDonald.
