In a back-and-forth contest that saw 10 breaks of serve, Zverev finished strongest in a 5-7, 6-3, 7-6(5) victory to reach his second Monte Carlo semi-final.
The high level of play throughout the match was not affected by the physical problems the players battled -
Sinner with a foot blister and Zverev with a right thigh problem. Despite both men looking uneasy at times in between points, there was no let-up when the ball was in play as both combined big power with exceptional angles and touch in a thoroughly entertaining contest.
Zverev said:
“It means a lot, definitely, especially [with] how this year has been going so far for me. I’ve lost long matches like that, so I’m happy I won this one."
Zverev repeateadly found comfort in this win having lost matches like this in the past:
“I’ve lost so many matches [like that] this year. I guess it’s in the back of my mind and I think this one will definitely help.”
