Novak Djokovic beat Argentina’s Juan Ignacio Londero 6-4, 7-6(3), 6-1 in Arthur Ashe Stadium to improve to 14-0 in second-round matches in Flushing Meadows.
Djokovic notched his 71st victory at the season’s final Grand Slam, moving into fifth place in the Open Era and tying his former idol Pete Sampras.
"I want to congratulate Londero for showing a great fighting spirit and playing some great tennis tonight,” Djokovic said on court after the match. “It's a straight-sets win, but it was definitely a very difficult match to play. A lot of rallies, especially in the first couple of sets.”
The Serb awaits the winner of 27th-seeded countryman Dusan Lajovic and American Denis Kudla for a spot in the Round of 16.
