PARIS -- Fourth-seeded Agnieszka Radwanska beat 2008 champion Ana Ivanovic of Serbia 6-2, 6-4 on Sunday to reach the French Open quarterfinals.
The Pole converted five of her nine break-point opportunities to reach the last eight at Roland Garros for the first time.
The 14th-seeded Ivanovic has now lost seven straight matches to Radwanska, who next plays last year's runner-up, Sara Errani of Italy.
The fifth-seeded Errani earlier rallied to win 5-7, 6-4, 6-3 against 20th-seeded Carla Suarez Navarro of Spain.
