Top-seeded Frenchman Richard Gasquet ended the hopes of big-serving qualifier Albano Olivetti, defeating his fellow countryman 6-4, 6-2 Friday night to advance to the semifinals of the Open Sud de France in Montpellier. Gasquet’s superb shotmaking and all-court coverage were too much for the 6-foot-8 Olivetti, who had 13 aces, but failed to force a single break-point chance against the defending champion’s serve and lost his own three times. Olivetti finished the tournament with 111 aces in six matches (including three qualies). The No. 9-ranked Gasquet defeated compatriot Benoit Paire in last year’s final. By advancing to the quarterfinals, Olivetti, ranked No. 249, matched his best tour-level performance. He also reached the final eight at Marseille in 2012. “I’m happy with the victory,” Gasquet said. “Matches like the one tonight, in front of a very good server, are always very uncomfortable. I had already trained with Albano, so I knew what he was capable of. You need to wait for your opportunity and make no mistakes when there is a chance.” Gasquet will play No. 3 seed Jerzy Janowicz in the semifinals tomorrow. Olivetti’s only real hope against a seasoned veteran like Gasquet was to get a high percentage of his first serves in. The 22-year-old failed that task, landing only 50 percent of his first deliveries, not nearly enough to hold Gasquet at bay. Gasquet hit 26 winners and committed just five unforced errors. Olivetti had 32 winners and 29 unforced errors. The aggressive Olivetti won just 15 points on 37 trips to the net.
