Montreal: Even a rain delay barely slowed defending champion Serena Williams in her 6-0, 6-2 progress past Samantha Stosur Wednesday at the WTA hardcourt tournament at Montreal. Williams, the world number one and top seed, had seized the first set and they were knotted at 1-1 in the second when rain halted play.

The American showed no ill-effects when they returned to the court, wrapping up the victory over the unseeded Australian in 58 minutes. Williams stretched her career record over Stosur to 7-3. The Australian stunned Williams in the final of the 2011 US Open, but Williams has now won all three of their meetings since. French Open champion Maria Sharapova had to rally for a three-set victory over Garbine Muguruza to reach the third round.
