Third-seeded Pablo Cuevas of Uruguay defeated Paul-Henri Mathieu 7-6 (7), 6-1 in a repeat of the 2009 semifinal that was won by Mathieu. Cuevas fired 12 aces and won 79 percent of his service points to beat Mathieu.
Stephane Robert of France beat eighth-seeded Guillermo Garcia-Lopez of Spain 7-6 (4), 4-6, 6-3.
