Novak Djokovic shook off the effects of a sore left shoulder to beat the unseeded Denis Kudla, 6-3, 6-4, 6-2, on Friday night.

Djokovic, the No. 1 men’s seed and defending champion, was hampered by the injury during his second-round match against Juan Ignacio Lóndero on Wednesday. But he appeared fit and focused on Friday.

“I’m very glad with the way it went,” he said about his shoulder. “I am able to play. That for me is a huge blessing today because it was probably the complete opposite two days ago.”

He would not specify what the injury was, but he said he played “almost” pain free.

Djokovic’s next opponent will be the No. 23 seed Stan Wawrinka, who beat Paolo Lorenzi of Italy, 6-4, 7-6 (9), 7-6 (4), to set up an intriguing fourth-round matchup on Sunday.
