Djokovic speaking about injured left-shoulder after win over Londero: "It has caused hindrance to my game for sure tonight"

Djokovic had significant problems during the match, being a break down in the first set and in the second even two, but in both cases he managed to win the set and guarded the situation in the third.

"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.”

"He brings focus and intensity on the court. He showed tonight a great spirit of someone that never stopped believing. Unfortunately for him, he was leading 3-0 and serving in the second set, and I found a way to get back in the second set," Djokovic said. "But he was playing well. He was hitting the ball really, really nice from the forehand side, especially. He made me work. I had to run a lot to earn this victory."

Djokovic also asked for a medical time-out during the match so he commented on his problems with shoulder after the match. Last year's winner mentioned that this is an unknown situation for him.

"It has caused hindrance to my game for sure tonight, especially with the serve and backhand. It was not easy to play with this kind of sensation, to be honest. I did not experience that too many times in my career," said Djokovic of his left shoulder. "I was also lucky to find my way back in the second set and to win in the straight sets."

"The way it has started for me, especially midway through the first set, I didn't know if I would be able to finish the match," Djokovic said. "I'm really glad I have."
