Nadal, who's won two of his 17 Grand Slam titles at Wimbledon, edged 2009 U.S. Open champion Juan Martin del Potro 7-5, 6-7 (7), 4-6, 6-4, 6-4 in a wildly entertaining match that featured diving shots by both and lasted 4 hours, 48 minutes.
Novak Djokovic believes he is peaking at the right time as he looks to return to past glories by challenging for the title at Wimbledon.
Djokovic was kept waiting in the wings till after 7pm local time before he could start swinging his racket against the Russian but there was no stopping the Serb once he got on court. One bit of drama came when Djokovic was given a warning for throwing his racquet.
Anderson hit 13 winners and just four unforced errors in the fourth set as he claimed the only break to force a decider. "I am trying to get in the best possible shape for the biggest possible events and it doesn't come much bigger that Wimbledon.", said Novak Djokovic. "I didn't harm the grass", he said.
He then let rip at Ramos for failing to sanction Nishikori for a similar act of frustration in the fourth set. I really do. I think with the performances I've had, I deserve to be in the semi-finals.
Defending champion Roger Federer has been knocked out of Wimbledon after wasting a match point during a 2-6, 6-7 (5), 7-5, 6-4, 13-11 defeat to Kevin Anderson of South Africa on Wednesday. Djokovic was heard saying on the BBC broadcast on Wednesday. The 31-year-old celebrated the four-year anniversary of his marriage to his wife, Jelena.
The 12-time Grand Slam champion then raised his level in the fourth set and finished with a victor into the corner to book his place in Friday's semi-finals where he was joined by a familiar foe as Nadal won through late in the day.
The 2011, 2014 and 2015 champion was clearly unsettled by the dispute, quickly surrendering the set.
A year ago, officials refused to move Djokovic's match with Adrian Mannarino on to Centre even though the court sat empty, while on Monday they opted to give priority to a mixed doubles encounter once Roger Federer, Serena Williams and Rafael Nadal had all swiftly booked their quarter-final berths.
"I like the level of tennis that I'm playing on right now", Djokovic said. "I knew how I threw the racquet", he said. "I think that's not fair".
"I want to use today's result as a spring from which to aim for a final place". "The expectations he's had to deal with for over a decade, 15 years, I mean, at the top of the game, he's able to deal with it so well, which isn't easy".
