The 19-time Grand Slam champion 36-year-old Federer outlasted US 19-year-old Frances Tiafoe 4-6, 6-2, 6-1, 1-6, 6-4 in a shockingly tough battle that boosted his hopes of a deep run on the New York hard-courts.
The third seed will next meet either Russia's Mikhail Youzhny or Slovenia's Blaz Kavcic as he chases a record sixth US Open crown.

Meanwhile, the two-time champion in New York, 31-year-old Nadal began his campaign for a third US Open title with a 7-6 (8/6), 6-2, 6-2 win over Serbia's Dusan Lajovic.
"When I was down in the first set, I just tried to be there as he was playing well and controlling the points," said French Open champion Nadal, who is chasing a 16th major.
"But the end of the first set was very important. I got the break back and after that, everything changed."
The world number one will face either Taro Daniel of Japan or Tommy Paul of the United States for a place in the last 32.
Nadal and Federer have never faced each other at the US Open but could meet in this year's semi-finals.
