Frenchman Lucas Pouille claimed his first ATP title by beating Austrian top seed Dominic Thiem 7-6(5), 6-2 in the Moselle Open final in Metz on Sunday.
World number 18 Pouille, seeded third, overcame a 4-0 deficit in the opening set's tiebreak to down Thiem, who made too many unforced errors.
Pouille, who has been enjoying a fine end of season after reaching the quarter-finals at this month's U.S. Open, rode his momentum by breaking in the first game of the second set.
He broke again in the seventh game to lead 5-2 before wrapping it up with his 10th ace.
