With a 6-4, 7-6(2) victory over Coco Gauff, Simona Halep secured another semifinal berth at the National Bank Open presented by Rogers.

Halep has noticed the improvement in the American teenager in that time.
"She's a bit stronger. She hits stronger. And the serve was much stronger today. Backhand is always hard," she said after the match. "I think she improved a lot since we played last time. It's always tough to play against her. She's fighting until the end. She doesn't give you a point, so you have to stay there and to fight."
