Roger Federer continued his bid for a record sixth US Open title with a comfortable second-round win over France's Benoit Paire.
The 37-year-old Swiss eased to a 7-5 6-4 6-4 victory in New York City in one hour 56 minutes.
Paire had not beaten the 20-time Grand Slam champion in six previous meetings and never looked like causing an upset.
Second seed Federer will play Australia's Nick Kyrgios in the third round.
Kyrgios won 4-6 7-6 (8-6) 6-3 6-0 against France's Pierre-Hugues Herbert, fighting back from a set and a break down after being talked to by chair umpire Mohamed Lahyani.
