But Djokovic eventually found the breakthrough after missing out on his first match point on Zverev’s serve before making no mistake on his second opportunity.
He said: “With this kind of condition, I need time to warm up. Even though I had alost hour of a warm-up hit before the match, it still felt it was going to take some time to warm-up and feel I could rotate in the right way.
I was lucky to get that break in the tenth game when he was serving for the fist tem.
It was a close tiebreak. After that I felt I started moving better, playing better. I served extremely well. Down to the very last shot, it was anybody’s game, anybody’s match.
A lot of nerves out there. A lot of pressure. Emotionally I feel a little bit drained. It was a great battle. Congratulations to Sascha. We pushed each other to the limit.”
There was a sigh of relief from Djokovic as he walked to the net to embrace his opponent and will now get ready to face Aslan Karatsev in the semi-finals.
