CINCINNATI - French Open finalist Lucie Safarova advanced to the quarter-finals of the ATP and WTA Cincinnati Masters on Thursday when injured opponent Belinda Bencic quit trailing 6-2.

The 12th-ranked Swiss teenager who beat Serena Williams and Simona Halep on her way to the Toronto trophy last weekend, lasted only 33 minutes, receiving treatment midway through the set on her right wrist.

After losing the opener, Bencic, who had won her last eight matches and streaked to the biggest title of her young career, retired.

With the US Open starting a week from Monday in New York, caution likely played a role in her decision.
