The world number one beat the 18-year-old NCAA champion 6-1 6-3 7-5 in an entertaining first round match on the Arthur Ashe Stadium court.
The victory extends his remarkable winning streak at the U.S. Open to 35 matches as he bids to win a sixth consecutive title at the hardcourt grand slam.
Federer breezed through the first set for the loss of a single game, but Britton served notice of his promise by breaking to take a 3-1 lead in the second set.

Britton, who went for broke with a total of 32 winners, took advantage of a sloppy game by Federer to break again for 4-3 in the third set, only to be let down by unforced errors in the next game as the 15-time grand slam champion broke back.
