NEW YORK — Defending champion Novak Djokovic's left shoulder appeared to be just fine as he put together a straightforward, straight-set victory over Denis Kudla to reach the US Open's fourth round for the 12th appearance in a row.
The top-seeded Djokovic won, 6-3, 6-4, 6-2, under the lights in Arthur Ashe Stadium.
He had complained about pain in his shoulder and repeatedly was visited by a trainer during his previous match.
Next will be a match Sunday against three-time major champion Stan Wawrinka.
Djokovic has won 36 of his past 37 Grand Slam matches.
He is pursuing a fourth title at the US Open and 17th major trophy overall.
