The forehand that grazed the sideline, the temple tap to her team, the sprint around the court. All of it pointed to a player in Iga Swiatek who is as composed as she is ruthless.

Around 8 p.m. Monday, Iga Swiatek was holding up her Cincinnati Open championship trophy. Around 8 a.m. Tuesday, she was getting ready for her mixed doubles match at the U.S. Open in New York City. It’s been a quick turnaround.

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.
