STUTTGART, Germany (AP) Defending champion Maria Sharapova defeated Anastasia Pavlyuchenkova 6-4, 6-3 on Thursday to set up a Porsche Grand Prix quarterfinal with top seed Agnieszka Radwanska.
The sixth-seeded Sharapova needed a little over an hour and a half to defeat her fellow Russian, keeping alive her dream of winning the tournament for the third year in a row.
Polish world No. 3 Radwanska was rarely troubled in wrapping up a 6-3, 6-2 win over Italy's Roberta Vinci.
