On Monday night, Iga Swiatek won the Cincinnati Open. On Tuesday, she played two U.S. Open doubles matches in New York City.

Iga Swiatek has confirmed her participation in today’s US Open mixed doubles event despite a rapid turnaround from her victory at the Cincinnati Open on Monday night. The Polish star, who won Wimbledon last month, did not drop a set all week in Cincinnati and defeated Jasmine Paolini 7-5 6-4 to lay down a marker ahead of the US Open.

After back-to-back semifinal losses over the last two years, Iga Swiatek broke through Aug. 17, beating Elena Rybakina for a spot in the finals.
