Poland’s world number 13 Hubert Hurkacz won his third ATP title of the year with victory over Pablo Carreno Busta in the Moselle Open final.
The top seed rallied from a breakdown in the first set to beat the Spaniard 7-6 (7-2) 6-3 in Metz.
It is his first indoor title and his first outside the United States.
Hurkacz, who defeated Britain’s former world number one Andy Murray in the quarter-finals, did not drop a set throughout the tournament.
Elsewhere, South Korea’s Kwon Soon-woo won the Astana Open in Kazakhstan for his maiden ATP Tour title.
Kwon became the ninth first-time winner on the tour this year, beating Australia’s James Duckworth 7-6 (8-6) 6-3.
And Britain’s Liam Broady won his first ATP Challenger title with a 7-5 6-3 victory over Swiss Marc-Andrea Husler in Biel, Switzerland.
