Ruthless Williams progresses
Serena Williams remains on track for her eighth WTA Tour title of the season after cruising into the semi-finals of the Rogers Cup in Toronto.
Williams blitzed world No 42 Magdalena Rybarikova 6-1 6-1 in just an hour to set up a clash with Agnieszka Radwanska for a place in Sunday's final.
The world No 1 smashed down seven aces and broke the Slovak's serve on six occasions in a one-sided encounter that boosted her confidence and made it eight wins on the trot since her Wimbledon exit to Sabine Lisicki.
"She had nothing to lose," Williams said of Rybarikova. "I knew I had to play really, really good today.
"I'm definitely happier with the return game. I could still use some improvement. She served pretty well, but I was pretty happy with the results from today."
Radwanska had things a lot tougher than Williams but dug deep to beat Italy's Sara Errani 7-6 7-5.
Williams has beaten Radwanska in all five of their previous contests, but the American said: "It's a good match-up.
"She does everything so well. She's having a much better year. It's going to be an interesting match. It's definitely not going to be easy. I hope I can play well. I can only hope that I come out on top."
