MASON, Ohio (AP) Seventh-seeded Gregor Dimitrov defeated Feliciano Lopez 7-6 (5), 6-4 on Wednesday to reach the Western & Southern Open’s round of 16.
Sixteenth-seeded Madison Keys easily reached the women’s round of 16 in Cincinnati for the first time on her fourth try, needing just 50 minutes to zoom past Daria Kasatkina 6-2, 6-1. Keys, a right-hander who withdrew from last week’s Rogers Cup in Toronto with a left forearm injury, next will meet fourth-seeded Garbine Muguruza, the Wimbledon champion.
“I definitely thought I played really well,” Keys said. “I don’t know if I was the zone, press, but everything was going well. It was falling into place, and I didn’t have to rush anything.”
Keys was happiest about finishing quickly in the humid, 80-some-degree conditions.
“I definitely didn’t want to be out there a long time,” she said. “I wasn’t out there that long, but I was still drenched. I was happy to get back inside into the air conditioning.”
After being forced to a tiebreak in the first set, Dimitrov raised his level of play in the second with 13 winners to Lopez’s four. Dimitrov finished with 28 winners, twice as many as Lopez.
Other seeded women reaching the third round in this U.S. Open warmup were eighth-seeded Svetlana Kuznetsova, with a 6-3, 6-4 win over Yulia Putintseva, and Anastasija Sevastova, with a 6-2, 7-5 win over Roberta Vinci. Qualifier Camila Giorgi advanced with a 7-6 (1), 5-7, 6-3 win over Daria Gavrilova.
Men reaching the third round on the third full day of play included David Ferrer, 6-4, 6-7 (5), 6-1 over Janko Tipsarevic, and Yuichi Sugita, 3-6, 7-6 (5), 6-1 over qualifier Joao Sousa.
