Thursday's schedule at the Western & Southern Open

MASON, Ohio ‒ Four Americans are through to the Round of 16 in both the women's and men's draws at the Western & Southern Open. This marks the first time since 2019 that four US women are into the third round, with Madison Keys, Jessica Pegula, Alison Riske-Amritraj and Shelby Rogers taking the court Thursday. Since the WTA returned to Cincinnati in 2004, there have never been more than three Americans into the quarterfinals.

Sebastian Korda and John Isner will face each other in an all-American third-round match Thursday, and they are joined in the Round of 16 by Americans Taylor Fritz and Ben Shelton. It's the most Americans into the third round since five reached this stage in 2003.
