“The tiebreaker was very tense,” the winner said, “But I didn’t panic, I review my tactics and came through.
“I felt comfortable playing him even if he is very unpredictable with a good game.
I didn’t know exactly what to expect coming into the match.”
Tsitsipas will next face a re-run of the Hamburg final he lost eight days ago as he plays Andrey Rublev.
