Novak Djokovic was breathing easier after saving a match point and managing an opening victory over Tomas Berdych to begin his campaign at the ATP World Tour Finals.
But it was the encouraging state of his right shoulder that most pleased the world No. 1.
"This was my toughest match probably since the US Open," said Djokovic of a battle lasting well over two hours. "I wasn't very satisfied with my performance - I know I wasn't playing on top of my game.
"To be honest, it feels good, that's something that I'm happy about. I haven't felt any pain in my shoulder. I've been feeling well on the court.
"Obviously, I feel a little bit exhausted, because the match was almost three hours. It's normal. But I think I'm physically fit. And I just need to get some things better in my game for the next challenge."
Djokovic has been dealing with the shoulder for almost a month after healing a back injury from September's Davis Cup.
