Świątek, one tournament removed from her stunning Wimbledon title, won the most important U.S. Open tuneup by beating Jasmine Paolini 7-5, 6-4 in the final of the Cincinnati Open. She is back to No. 2 in the rankings. She is within shouting distance of world No. 1 Aryna Sabalenka.

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.
