Mathieu upsets Lopez in 1st round in Rotterdam

ROTTERDAM, Netherlands (AP) - Paul-Henri Mathieu rallied from a set down Monday to upset fourth-seeded Feliciano Lopez 4-6, 7-6 (5), 6-4 in the opening round of the ABN Amro World Tennis Tournament.

Mathieu, ranked No. 733 after missing the entire 2011 season with a knee injury, looked sharp in beating Lopez in a match that lasted nearly three hours.

He says he worked hard during his rehab and calls this a "good comeback.''

Another Frenchman, fifth-seeded Richard Gasquet, defeated an injured Flavio Cipolla to win his first-round match 6-3, 1-6, 6-1. After losing the first set, Cipolla easily took the second, but struggled in the decider with a left thigh injury.
