World No 1 Serena Williams continued her dominance over Germany's Andrea Petkovic with a 6-3, 6-2 victory in the third round of the WTA Rogers Cup in Toronto on Thursday.
Top seed Williams hammered 28 winners and blasted nine aces to beat the 16th seeded Petkovic for the fifth straight time.
"I think I served better than in my first match. It was a big difference," Williams said. "I still think I have a tremendous amount of improvement to do off the ground and everywhere else."
