Eighth-seeded Guillermo Garcia-Lopez of Spain beat third-seeded Benoit Paire of France 7-5, 7-6 (4) on Friday to reach the semifinals of the Grand Prix Hassan II.
Garcia-Lopez served for the match after breaking Paire for the fifth time, but the Frenchman broke straight back to force a tiebreaker.

Also, fourth-seeded Marcel Granollers of Spain had nine aces as he rallied to beat Pablo Carreno Busta 6-7 (4), 6-3, 6-0 in an all-Spanish match, breaking his opponent's serve six times.
He next faces No.6 Federico Delbonis of Argentina, who beat Victor Hanescu 7-6 (5), 6-3, breaking the Romanian player's serve four times.
