Sara Errani of Italy showed her surprising run at the French Open last year was no fluke as she beat fourth-seeded Agnieszka Radwanska of Poland 6-4, 7-6 (6) Tuesday in the quarterfinals of the Grand Slam tournament in Paris.
Errani rallied from a 3-1 deficit in the second set to break for a 5-4 lead but then failed to serve out the match. However, the 2012 runner-up did not falter in the tiebreaker, converting her second match point when Radwanska hit a backhand wide.
The fifth-seeded Errani will next face either No. 1 Serena Williams of the United States or Svetlana Kuznetsova of Russia.
Radwanska was the first Polish woman to reach the quarterfinals at Roland Garros in the Open era, which started in 1968.
