Martin Klizan rallied past fifth-seeded Frenchman Gael Monfils 6-7 (7-1) 6-3 6-1 to win the indoor World Tennis Tournament in Rotterdam on Sunday.
The 26-year-old Slovak, who saved eight match points on his way to the final, won six of the seven break points he faced against Monfils in their two-hour match.
Monfils had 12 aces but was broken five times.
The Frenchman could not convert six break points in the first set before he prevailed in the tiebreaker.
But Monfils handed his opponent the first break of the match in the eighth game of the second set with a double fault and his play collapsed afterward.
Monfils won only six points as Klizan led the decider 5-0 and sealed the match with a forehand winner to capture his fourth career title.
