Simon, 23, defeated Benneteau 7-5, 6-2 for his third career ATP singles title and his first this year.
This was 26-year-old Benneteau's first-ever ATP-level final in 102 tournaments. His previous best result came in January when he advanced to the semifinals in Auckland. He also was a quarterfinalist in Las Vegas in March.
To advance to the final, Benneteau came from behind to beat Argentine Agustin Calleri 1-6, 6-1, 6-3. Simon, a qualifier, advanced via walkover when top-seeded fellow Frenchman Jo-Wilfried Tsonga withdrew from their scheduled semifinal bout Friday with a knee injury.
