Benoit Paire ensured the Moselle Open will have a home finalist after he brushed aside Nikoloz Basilashvili 6-1 7-6 (7-5) in their semi-final.
Frenchman Paire will face German qualifier Peter Gojowczyk in Metz on Sunday after hitting 17 aces in his victory over Georgian Basilashvili, a win which was wrapped up in an hour.
Paire had defeated David Goffin in the quarter-final after saving match point, and dropped just seven points on his first serve in a commanding display in Saturday's last-four clash.
Gojowczyk, meanwhile, was 6-3 1-0 up against compatriot Mischa Zverev when the fifth-seeded German was forced to retire.
Paire missed the opportunity to make a second final as he and doubles partner Paul-Henri Mathieu were defeated 6-4 6-4 in the semi-finals by fellow Frenchmen Julien Benneteau and Edouard Roger-Vasselin.
Benneteau and Roger-Vasselin will take on Wesley Koolhof and Artem Sitak in the final.
