German qualifier Peter Gojowczyk became just the second non-Frenchman to win the Moselle Open in nine years with a straight-sets victory over Benoit Paire in Sunday's final.
Ranked 95 in the world, Gojowczyk overcame history to prevail 7-5 6-2 and claim his maiden ATP World Tour title.
Seventh seed Paire had been favourite to continue the tournament's trend of homegrown winners, but he was blown away after a tight first set.
Despite sending down nine aces to one in the opener, Paire blinked first on serve as Gojowczyk consolidated a late break to seize the advantage.
And the unheralded Gojowczyk, playing in his first final, never looked back after taking full control with a pair of breaks at the start of the second set.
Gojowczyk becomes the first qualifier to win an ATP World Tour title since Nicolas Mahut in 2015.
