Alexander Zverev thinks his win over Novak Djokovic at the Olympics is responsible for his big US Open performances.
Zverev took another step towards a second successive US Open final as he beat Jannik Sinner on Monday.
It was another powerful display from Zverev, who arrived in New York having won the Olympics gold medal and the Cincinnati Open.
It was the Olympics that really gave him the impetus, though, with him coming from behind to overpower world number one Novak Djokovic, and he says he has been benefitting from the confidence that generated ever since.
"The Novak match gave me a lot, because I was down and out basically from the match," Zverev said.
"Coming back against the world number one the way I did, and I won what, 10 out of 11 games after being a break down in the second set, that did give me something.
"I'm hoping to use it and continue using it here."
"It has built over time to do it in the most important moments. To hit those kind of balls in the important moments, I think that's probably matches, that's a lot of tournaments and all that.
"In Tokyo, all of a sudden it clicked, because in Wimbledon I had a very bad serving match against Felix [Auger-Aliassime].
"That was the reason I lost. Yeah, since Tokyo, it's been a lot better, but it can still be a lot better, as well."
"I'm happy where I am, I'm happy with how things are, and I'm happy with how things were the last few months."
