Defending champion Juan Martin del Potro of Argentina and Richard Gasquet of France won semifinals and will play for the title Sunday in the Estoril Open, a clay-court tuneup for the French Open. This is Gasquet's first final since July 2010.

The top-seeded Del Potro didn't surrender a break-point chance in beating third-seeded Stanislas Wawrinka of Switzerland 7-6 (2), 6-4. Gasquet, seeded second, rallied past Albert Ramos of Spain 2-6, 7-6 (1), 7-5.

Gasquet looked finished when he slammed his racket into the ground after losing a point at the start of the second set. But Ramos dropped his next service game with three straight errors.

Gasquet didn't waste the chance and drew even at one set each before finishing off the fourth-seeded Ramos in just over three hours when his return sailed wide.
