Canada's Felix Auger-Aliassime successfully defended his Open Occitanie championship on Sunday with a 6-3, 7-6 (4) victory over Adrian Mannarino in Montpellier, France.

Auger-Aliassime, 25, recorded 13 aces and won 87% of his first-serve points to dispatch the Frenchman in 1 hour, 35 minutes. The ninth career ATP title for Auger-Aliassime is one more than Milos Raonic for the most tour-level titles by a Canadian in the Open Era.

A strong service game was nothing new for Auger-Aliassime, who delivered 20 aces while posting a 6-4, 6-7 (5), 6-1 victory over French qualifier Titouan Droguet on Saturday.

Auger-Aliassime will elevate one spot to No. 6 in the ATP rankings on Monday.
