"Played one bad game and that almost cost me" says a happy Zverev after a straight sets win at US Open

Alexander Zverev advanced to the US Open quarterfinals after a win over Jannik Sinner. It was his 15th win in a row and he is positioning himself as one of the biggest threats to Novak Djokovic and his quest to a calendar grand slam. On the match Zverev said:

"Yeah, I think it was a pretty high-level match, to be honest. I think the winner and unforced error ratio was not like the other matches, not as good as the other matches, but it was also very difficult because both of us are playing extremely fast. All in all, I played one bad game in the third set and that almost cost me a set, and that shows how high I think both players were playing."

Jannik Sinner underlined after the match that a very key thing in the match was the serve of Zverev. Asked when it clicked for him serving-wise he said:

"Yeah, in Tokyo. In Tokyo, all of a sudden it clicked, because in Wimbledon I had a very bad serving match against Felix. 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. As I said as well, the serve is the shot I spend the most time on, it's the shot I practice the most as well. I am someone that needs that repetition, and I feel like the hard work maybe starts coming along."

Zverev will face Lloyd Harris for a place in the semifinal. The South African has been playing extremely well especially on his serve and Zverev had a bit of trouble with him in the past. They played twice with Zverev winning both matches but it was tricky to do so. On the matchup he said:

"I said, like, I feel Lloyd has been winning two, three matches every single week, doesn't matter where he's playing. He's showing the high level here again. Of course, the match is not over yet, but if it's against Lloyd, he's playing incredible and he's also serving incredible. In Cincinnati I was struggling a lot to return his serve in the first set. Yeah, it's gonna be a tough one, definitely."
