NICE, France (AP) Top-seeded Dominic Thiem of Austria beat German teen Alexander Zverev 6-4, 3-6, 6-0 to win the clay-court Nice Open final and clinch his third ATP title of the year on Saturday.
Thiem, ranked 15th, dropped serve four times but broke Zverev's serve six times on his way to a sixth career title.
The 19-year-old Zverev, who was seeded eighth and playing in his first career final, double-faulted nine times - including four times in the deciding set, during which Thiem did not face a break point and won every point on his first serve.
Thiem's other titles this year were on outdoor hard court at Acapulco and outdoor clay at Buenos Aires. Five of his titles are on clay.
Both players head to the French Open, which starts on Sunday.
