Three-time champion Serena Williams advanced to the quarterfinals but second-seeded Agnieszka Radwanska fell victim to an upset Monday at the U.S. Open.

Williams needed 56 minutes to decimate the Czech Republic”s Andrea Hlavackova, 6-0, 6-0, as the Olympic gold medalist eased into the final eight at Arthur Ashe Stadium.

The American star”s next opponent will be former world No. 1 Ana Ivanovic, who advanced with a 6-0, 6-4 decision over Bulgarian Tsvetana Pironkova at the USTA Billie Jean King National Tennis Center.

The 12th-seeded Serb, making her first appearance in a major quarterfinal since winning the 2008 French Open, is 0-3 lifetime against Williams.

Poland”s Radwanska, meanwhile, was upended by 20th-seeded Italian Roberta Vinci 6-1, 6-4 at Armstrong Stadium.

Vinci bested Radwanska for the first time in five career matches and now goes on to face doubles partner and fellow Italian Sara Errani, who surprised sixth-seeded German Angelique Kerber 7-6 (7-5), 6-3 to reach at least the quarterfinals at three of this year”s four Grand Slam events.
