All four of the "Big Four" in men's tennis have advanced to the second round at Wimbledon. On Monday, Novak Djokovic advanced with a win over Andrey Golubev in straight sets. Defending champion Andy Murray also won his opening match in straight sets, although the third set required a 7-5 game win from Murray over opponent David Goffin.
Nadal also advanced on Tuesday, although he was the only of the "Big Four" to drop a set. He dropped the first set to Martin Klizan before winning the next three sets.
In the second round, Nadal will face Lukas Rosol, while Murray will face Blaz Rola and Djokovic will face Radek Stepanek. Federer's opponent has yet to be determined, pending the match between Gilles Muller and Julien Benneteau. Federer lost in the second round at Wimbledon last year.
Stan Wawrinka, David Ferrer, Jo-Wilfried Tsonga, Tomas Berdych, and Milos Raonic also advanced to the second round. Check out the men's draws here.
