Defending champion Rafael Nadal suffered a major injury scare which pushed him to the brink of pulling out of his Wimbledon last 16 clash against Argentina's Juan Martin del Potro.
The world number one needed a lengthy medical time-out at 6-all in the first set of his last 16 clash to have his left foot bandaged.
Although Nadal went on to claim a 4 sets victory, which set up quarter-final against American 10th seed Mardy Fish, the Spaniard admitted he was close to quitting.
All four of the men's top seeds made the quarter-finals.
Number two Novak Djokovic saw off error-plagued Michael Llodra of France in straight sets.... third seed and six-time champion Roger Federer came back to defeat Russia's Mikhail Youzhny in 4.... and Andy Murray thrived in the 30-degree heat of the early afternoon to crush French 17th seed Richard Gasquet in straight sets.
Djokovic will face qualifier Bernard Tomic after the 18-year-old Australian became the youngest quarter-finalist since Boris Becker in 1986.
Tomic, the world number 158, reached his first Grand Slam quarter-final by seeing off Belgium's Xavier Malisse, a former semi-finalist, in straight sets.
Federer, who last won Wimbledon in 2009, has now reached 29 consecutive Grand Slam quarter-finals to extend his Open era record and remains on course to equal Pete Sampras's record of seven Wimbledon titles.... he'll next play France's Jo-Wilfried Tsonga in the last eight.
Murray, bidding to become Britain's first men's Wimbledon champion since Fred Perry in 1936, reached his fourth consecutive Wimbledon quarter-final.
His reward is a last eight clash against Spain's Feliciano Lopez who beat Polish qualifier Lukasz Kubot in a five-set marathon.
