Third-seeded Casper Ruud eased to a straight-set victory over Felix Auger-Aliassime in the opening match of the ATP Finals on Sunday.
The match was largely dominated by serving, and a solitary break in the seventh game of the second set proved enough for the Norwegian player to secure a 7-6 (4), 6-4 win over the fifth-seeded Auger-Aliassime of Canada.
Ruud, who lost in the semifinals last year, and tournament debutant Auger-Aliassime will also face top-seeded Rafael Nadal and Taylor Fritz of the United States in the Green Group. Nadal and Fritz were playing each other later Sunday.
