Former champ Kuznetsova returns to quarterfinals at French Open by beating Kerber

Former champion Svetlana Kuznetsova earned a berth in the quarterfinals at the French Open by beating Angelique Kerber 6-4, 4-6, 6-3 Sunday.

Ranked 39th and unseeded, Kuznetsova has reached the final eight in back-to-back major tournaments for the first time since 2009, when she won the title at Roland Garros. She reached the quarterfinals at the Australian Open in January before losing.

Kuznetsova whacked a forehand winner on match point, then let out a jubilant scream. The two-time major champion improved to 12-2 this year in three-set matches, and her winning percentage of .820 (41-9) at Roland Garros is the best among active players.

She'll next face the winner of the match Sunday between No. 1-seeded Serena Williams and No. 15 Roberta Vinci.
