MARRAKECH, Morocco (AP) -- Top-seeded Albert Ramos-Vinolas was near-perfect on his first serve to dispatch Moroccan wild-card entry Amine Ahouda 6-1, 6-2 in just over an hour to reach the second round of the Grand Prix Hassan II on Tuesday.
Ramos-Vinolas of Spain took 20 of 22 points on his first serve to win in 68 minutes. He reached the final in Marrakech in 2012 when he lost to compatriot Pablo Andujar.
However, fifth-seeded Robin Haase of the Netherlands and seventh-seeded Alexandr Dolgopolov of Ukraine both lost their first-round matches.
Mirza Basic beat Haase 4-6, 6-4, 7-5 while Dolgopolov, who was returning from a right wrist injury, was beaten 6-2, 6-3 by Italian qualifier Andrea Arnaboldi.
Two former champions went through in straight sets as Andujar beat Ilya Ivashka 6-3, 7-5 and 2014 winner Guillermo Garcia-Lopez ousted French qualifier Calvin Hemery 6-2, 6-2.
