Wimbledon is the only grand slam where Nishikori has yet to reach the quarterfinals. "I asked him. So, yes, it was quite a odd decision from (the) chair umpire, but it happens". "It's always like a big war for me when I play Novak".
Asked whether it was exciting to be involved in such a tight encounter against Istomin, where the only service break of the entire match arrived in the penultimate game, Kyrgios was not ready to accept the premise.
Novak Djokovic shrugged off a bad call by the chair umpire that cost him a break in his win over home favorite Kyle Edmund.
Although the two have never met on grass, Nishikori is still hamstrung by the knowledge that the last of his two wins against the Serb was in 2014 in a memorable semifinal victory at the US Open. "To go there and not really enjoy the moment, I think that's the part I regret the most", she said.
American ninth seed John Isner also reached his first Wimbledon quarter-final at the 10th attempt on Monday with a 6-4, 7-6 (10/8), 7-6 (7/4) win over Greek teenager Stefanos Tsitsipas.
Fourth seed Alexander Zverev continues to fall short at Grand Slams as the German was knocked out by world number 138 Ernests Gulbis 7-6 (2) 4-6 5-7 6-3 6-0 in the third round. That precipitated a lengthy absence from the tour and a worrying dip in form and confidence.
"Approaching Roland Garros and Wimbledon this year for me is quite different from any other year because of circumstances that I was in in the last 12 months, the injury, the surgery, so forth", Djokovic said. I haven't spent too much time on the court.
"I was 100 percent convinced it (bounced) twice", Djokovic said.
That was a boost after a shock quarterfinal exit at the French Open to world number 72 Marco Cecchinato of Italy. "I feel like I'm one of the guys that can cause a bit of an uproar at this event", Kyrgios said. "Indian Wells, Miami, most of the clay court season", added Djokovic.
"I think when you come back you enjoy little more tennis and I think you got to fight little more".
"I was a top-three player for so many years in a row, it was quite a unusual feeling for me not to be able to deliver my game that I know that I possess, that I know I've been delivering for so many years". Everybody does. 'He has a good team around him, people who know how to work, who know what to give him, these extra things.
