The Greek teenager - who has surged to No. 27 in the world rankings from No. 168 a year ago - reached his first career semifinal at an ATP World Tour Masters 1000 event. 'I do remember when I played Djokovic, I was able to get to the point, and I was able to construct points the way I wanted to. But even the Andy one, I was a little surprised by that one just because he was entered on his protected ranking, and the Federation chose to help him out so he could pull out with his protected and get a wildcard entry so he could save it for another tournament.

"I was really not focusing on winning or losing, just on starting to play good tennis and start building the right habits". "I'm putting Greece more deep into the map of tennis", Tsitsipas said. "I just patiently waited for the moment and it happened".
"The Canadian teenagers are great players", the former world No. 1 said.
A win for Djokovic would set up a potential quarter-final clash with German second seed Alexander Zverev, who advanced to the third round after a 6-4 6-4 win over Bradley Klahn.
Milos Raonic of Canada was scheduled to follow Djokovic's win on center court, but that match was delayed by rain. "With each game, with each point that I play, I feel more confident, more stable on the court, and everything falls into its place".
"I think I'm improving".
Sixth seed Marin Cilic continued his quiet progress, beating Argentine 11th seed Diego Schwartzman 6-3, 6-2.
