US Open champion Sloane Stephens advanced to the Rogers Cup quarterfinals, beating Carla Suarez Navarro 6-2, 7-5 in the hard-court event.
After Suarez overcame a 5-1 deficit to tie the second set at 5, Stephens broke serve for a 6-5 lead and scored four straight points to put away the match, ending it with a sharp cross-court forehand.
"Maybe the old me would have kind of freaked out," Stephens said.
"I was kind of like, 'OK, it's fine, she's allowed to play well. Just kind of regroup.' I did that. I was happy with that."
