Jo-Wilfried Tsonga beat Gilles Simon 7-6(5) 1-6 6-2 in an all-French final at the Moselle Open to claim his 12th ATP title on Sunday.
The third-seeded Tsonga eventually had too much power for his second-seeded opponent in a rematch of the 2013 final won by Simon.
"I am very happy, it was a big first set," said Tsonga.
"It's always tricky to play against Gilles, the ball always comes back."
Simon added: "He was more solid than me on the important points, especially in the first set."
Tsonga misfired some 20 forehands in the opening set but he still won the tiebreak 7-5 after saving six break points.
Simon, however, regained control and bagged the first five games of the second set, levelling to one set all when Tsonga netted a forehand.
The former Australian Open runner-up found his range in the decider, breaking for a 3-1 lead before ending the contest when Simon's forehand bounced out following a net cord.
