Sharapova stumbles to win, Nadal advances

PARIS (AP) - Maria Sharapova moved into the quarterfinals at the only Grand Slam tournament she hasn't won by dispensing with tactics and swinging away until she finally pulled out a 6-4, 6-7 (5), 6-2 victory over 44th-ranked Klara Zakopalova of the Czech Republic at the French Open on Monday.

Defending champion Li Na's surprising exit came against Yaroslava Shvedova of Kazakhstan, an eyeglasses-wearing doubles specialist ranked 142nd in singles who needed to go through qualifying rounds to enter the main draw.

Rafael Nadal's pursuit of a record seventh French Open title rolled on with another rout, this one a 6-2, 6-0, 6-0 victory over his pal, Juan Monaco of Argentina, who's not exactly a slouch - he was seeded 13th and has won five clay-court titles.

Three-time major finalist Andy Murray Murray ignored a poor start to win 1-6, 6-4, 6-1, 6-2 over Richard Gasquet. Next for Murray is a quarterfinal against No. 6 David Ferrer, who overwhelmed No. 20 Marcel Granollers 6-3, 6-2, 6-0.
