No. 1 Djokovic made 100 unforced errors in his 6-3, 6-7 (1), 6-4, 4-6, 6-3 win in four hours, 32 minutes over Simon.
“I made a lot of unforced errors today,” Djokovic said after the win. “Nevertheless, he was fighting. He was playing well. Physically very demanding. I’m just happy to get through this one.”
The defending champion’s victory puts him in his 27 consecutive quarterfinal at a major equaling Jimmy Connors and behind Roger Federer with 36.
“These are the tournaments that we value the most and to be able to always come up with the best performance in the Grand Slams, of course I’m very proud of it and hopefully I can keep going,” Djokovic said.
“I don’t feel good,” Simon said about the loss.
“It’s always a bad feeling when you lose in five also. Always like when you play so long, you feel so many things are happening on the court. So many things could have been different. Just had, like, couldn’t make it today.”
“Gilles is a great defender,” the world No. 1 explained. “Always makes you play an extra shot. You have days like this, but fortunately you manage to fight your way through. I think in important moments the serve was getting me out of trouble. That’s what I take as a positive from today.”
No. 7 Kei Nishikori will be playing Djokovic in the quarterfinals. He defeated No. 9 Jo-Wilfried Tsonga 6-4, 6-2, 6-4.
“It’s gonna be big challenge to play Novak, for sure,” said Nishikori.
So what’s the most difficult thing when playing Djokovic?
“I think the biggest thing is he doesn’t miss,” Nishikori said. “He doesn’t give you easy points, any free points. I have to, you know, be the one to dictate. I think he’s serving well, too.
“It always makes tough player.”
Nishikori upset Djokovic in the 2014 semifinals at the U. S. Open.
“That (win) gives me a lot of confidence to play against him again, but we played in London and he, you know, kind of destroy me,” explained Nishikori. “It wasn’t easy match for me. It’s different condition, but I hope I can make some changes and try to play better.
“Yeah. I’m ready to beat him again.”
Roger Federer’s win over David Goffin lasted less than 90 minutes with a 6-2, 6-1, 6-4 score.
“It was good,” Federer said. “Surprised it went as fast as it did. You know, to win the first two sets within 50 minutes is the best thing that can happen out there, especially with a late start and against a quality player. So I was very happy.
“It was important to keep the momentum going, keep staying aggressive and, you know, trying to get the match done in three. I was able to do that. I was very pleased.
“There were some great moments in the match which I can take a lot away from. I was happy to, which after the Dimitrov match, which wasn’t so straightforward, wasn’t so easy, I was able to find an extra gear, I guess.”
Federer will match up against No. 6 Tomas Berdych in the quarterfinals. Berdych defeated Roberto Bautista Agut 4-6, 6-4, 6-3, 1-6, 6-3.
“I have to play well,” said the Swiss about his upcoming match against the Czech. “I think the court suits him. I think this sort of flatter bounce and faster court is good for his serves, good for his returns. It’s a fast court. I think for his kind of game it’s good.
“I think I matched up well against him as of late. Then again, we haven’t played that much. He played very well here last year in exactly these conditions. I was very impressed how he played against Nick (Kyrgios). Today I didn’t see that much against Bautista Agut. It was about switching to a different court, day session, beating a different kind of player, beating him in five sets, which gives him, I’m sure, a lot of confidence, as well, even though maybe the scoreline doesn’t suggest that.
“I would assume he’s exactly where he wants to be and he’ll recover and make it a tough match for me, no doubt about it.
“It’s going to be a good match. We’re both going to play aggressive. This court pays off when you do play good and aggressive tennis.”
“I think he’s playing really well, especially in the last season,” Berdych said of his next opponent. “He’s become a very, very danger(ous) opponent, as always he is. I mean, it’s always difficult to say something else or something new. I mean, it’s Roger, so it’s always going to be a huge challenge to play him. It’s the quarterfinal of a slam.
“Yeah, I like it. I like my chances. I’m just looking forward to that match.”
