Djokovic proved too strong for Fritz a fortnight ago – same again?
Hello and welcome to coverage of the first men’s quarter-final at the US Open as Novak Djokovic plays Taylor Fritz.
Fritz is one of three Americans who are into the last eight but he faces the tough task of beating the 23-time grand slam champion.
“I think the toughest thing is just convincing yourself that it’s, like, just play within yourself,” Fritz said. “I don’t need to find myself trying to hit serves bigger or aiming closer to the lines, stuff like that, because it’s Novak.
“I think I need to play within myself and trust that if I’m playing well, then that’s going to be enough, and I don’t need to kind of do anything extra.
“Novak’s Novak. It’s tough. I said it on court: he’s gotten me seven times. There’s no one on tour that has any kind of a record like that against me, so I’m hoping one of these times I’ve got to get him. US Open quarters would be a pretty good time to get him (smiling).”
Two weeks ago, Djokovic was too strong for Fritz, winning 6-0, 6-4 at the Cincinnati Masters and the Serbian is aware of the qualities his opponent possesses.
He said: “I’m going to get ready obviously for that match as any other match, doing my analytics, watching the last match we had against each other just few weeks ago in Cincinnati where I played a really, really, really good, really solid match, and won in straight sets. I’ll take some positives out of that.
“We know each other’s game pretty well. I’ve played him quite a few times actually in the last couple years. Yeah, big game. Serve and forehand are two biggest weapons, no doubt. But he has improved so much. He’s also playing very well on clay, which maybe wasn’t the case first years of his professional career.
“He’s working hard. He’s got a great coach in his corner. I’m sure he’s going to be very pumped and motivated to win. It’s going to be great atmosphere on the stadium and let’s see what happens.”
