Novak Djokovic noticed the ball bouncing differently in some patches. Otherwise, the women's match are actually more intresting.
The shiny grass courts often lose their sheen as the fortnight progresses, but issues with the slippery surface were heard earlier in the tournament than usual, and that is having an impact on players up and down the draw.
"It's their turf", said Ernests Gulbis, who stood in Djokovic's way in the third round but failed to present too much of an obstacle. So obviously different weather conditions can affect the quality of the grass, I would assume.
"I've been playing here a lot of years and I've never seen the courts that - I wouldn't say bad, but they weren't good". "I haven't had that kind of experience before in Wimbledon, to be honest". I felt that the court was not in great shape bounce wise. He had a whopping 61 winners and only seven unforced errors in his third-round victory over German Mischa Zverev, who competed well in the late-evening clash.
Gilles Muller has won more serve-and-volley points than any other remaining ATP player at Wimbledon thus far. "It's not a good sign, and you should always take the players' opinion serious". "The last thing we want to see is terrible injuries", added the Swiss.
Federer, whose court coverage has been electric, not just at Wimbledon, but all year, said it was all about positioning. If Federer advances to the semi-finals, we could see a re-match of the 2014 and 2015 Wimbledon finals, with Federer meeting Djokovic for a spot in the final.
Champion in 2008 and 2010, Nadal has experienced some hard years at Wimbledon since then and his days as a grass-court contender looked to be slipping away.
Ken Rosewall of Australia remains the oldest player to win a Grand Slam in the Open Era. "But how do you judge, you know-when you finish after a drop shot, it's been a tough rally, the guy has to run back to the baseline", he said.
When the draw was made just over a week ago, many fans would have anticipated a third-round contest between Djokovic and the popular Argentine Juan Martin Del Potro.
A hole was reportedly observed on the side of the court 18, which was said to have been caused by American Ryan Harrison during a practice session.
"Because we have daily monitoring, we can keep a very tight rein on everything", he said. So I'm not sure if it's that beneficial.
"I don't know if it's anything to do with the weather that they've had over the last few weeks and months".
Muller is playing his best tennis into his 30s, and although he has the ability to cause Nadal more than a few problems, it is hard to see Muller's serve-and-volleying style of game hold up over the entirety of a match against Nadal in this form, especially when you consider how unsafe Nadal is with his passing shots from the baseline. "This year seems like it's a bit softer". They sometimes get unsettled by playing in the 4,000-seater sunken bowl but Kerber, who won the U.S. and Australian Opens past year, should be more than a match for the world number 70.
