MONTPELLIER, France (AP) -- Defending champion Richard Gasquet remains on course to defend his Open Sud de France title after rallying to beat Dustin Brown of Germany 1-6, 6-4, 6-3 on Saturday, setting up an all-French final against veteran Paul-Henri Mathieu.

Mathieu earlier beat German teenager Alexander Zverev 7-6 (11), 7-5 in a hard-fought match.

Mathieu, who won the last of his four career titles in 2007, had nine aces and withstood 15 from the 18-year-old Zverev, who beat U.S. Open champion Marin Cilic in the second round.

The top-seeded Gasquet, ranked 10th, bids for his 13th career title.

He was in deep trouble but fought back from 3-0 down in the second set as Brown, who fired 17 aces in the match, started to get more nervous approaching victory.
