Gael Monfils beat Canada's Felix Auger-Aliassime 6-2 6-4 to win the Rotterdam Open for a second straight year.
Monfils, playing in his third Rotterdam final in five years, broke twice en route to serving out the opening set.
Auger-Aliassime, 19, saved four match points while trailing 5-2 in the second set but Monfils reasserted his dominance to win in 87 minutes.
The title was the second in seven days for 33-year-old Monfils after winning in Montpellier last weekend.
British number one Dan Evans was knocked out by third seed Monfils at the quarter-final stage.
Frenchman Monfils then beat Serb Filip Krajinovic in the semi-finals, while Auger-Aliassime beat Pablo Carreno Busta.
