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.

Iga Swiatek filled in a piece of her career tennis puzzle on Monday as she won the ATP-WTA Cincinnati Open for the first time with a 7-5, 6-4 defeat of Jasmine Paolini.Paolini dropped serve for 5-6, giving her opponent the chance to produce a love game and claim the opener 7-5 after just under an hour on court.

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.
