Roger Federer reached his 14th Wimbledon quarter-final and tied Martina Navratilova's all-time Grand Slam record of 306 match wins on Monday. The seven-time champion achieved his double landmark by seeing off Steve Johnson of the United States 6-2, 6-3, 7-5 in the fourth round on Centre Court. Federer, the third seed, next takes on Croatia's Marin Cilic for a place in the semi-finals.
Cilic, the ninth seeded Croatian, progressed to his third Wimbledon quarter-final when Japanese fifth seed Kei Nishikori pulled out of their last-16 clash with a rib injury in the second set.
Federer has a 6-1 record over Cilic but the big Croatian stunned the 17-time major champion in the US Open semi-finals in 2014 on his way to his maiden Grand Slam title.
Sam Querrey followed up his shock defeat of Novak Djokovic by beating French veteran Nicolas Mahut 6-4, 7-6 (7/5), 6-4 to reach his first Grand Slam quarter-final.
Querrey, the 28th seed, is the first American in the last-eight at Wimbledon since Mardy Fish in 2011. He will face either Canada's Milos Raonic or David Goffin of Belgium for a place in the semi-finals.
