Stanislas Wawrinka won the Monte Carlo Masters for the first time after rallying to beat Roger Federer 4-6, 7-6 (5), 6-2 in an all-Swiss final on Sunday.
The Australian Open champion had lost his previous two Masters finals and looked like losing a third until Federer's level dropped suddenly late in the second set, and Wawrinka began troubling the 17-time Grand Slam champion with his aggressive backhand.
The fourth-seeded Federer, who accepted a wild card invitation to play in the tournament, was also looking to win it for the first time after losing his three previous finals here to eight-time champion Rafael Nadal from 2006-08.
Wawrinka has beaten Federer only twice in 15 matches but both victories have come here. He also beat him in the third round in 2009.
