Serena Williams breezed into the quarter-finals of the US Open with a comfortable straight-sets win against Serbia's Ana Ivanovic. Ivanovic, the 16th seed, struggled on her serve throughout the match at a blustery Arthur Ashe Stadium, successful with only 51% of her first serves and winning only 29% of points on her second.
It was an up-and-down match featuring 16 breaks of serve, which was perhaps not surprising given Pavlyuchenkova hit 11 double faults and Schiavone 10. Pavlyuchenkova vowed to take the fight to her opponent in their quarter-final.
