LONDON, July 4: Roger Federer reached his 14th Wimbledon quarterfinal 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 semifinals.
Cilic, the ninth seeded Croatian, progressed to his third Wimbledon quarterfinal 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 semifinals in 2014 on his way to his maiden Grand Slam title.
