Roger Federer marches on at Wimbledon but reality bites for Dustin Brown
Conqueror of Rafael Nadal comes back to earth after slumping to defeat by Serbian Viktor Troicki

Seven-time champion Roger Federer swept aside big-serving Australian Sam Groth to reach the Wimbledon last 16 on Saturday while Dustin Brown, the conqueror of Rafael Nadal returned to earth with a bump.
Second seed Federer clinched a 6-4, 6-4, 6-7 (5-7), 6-2 victory over world number 69 Groth who fired a 235km/h ace in the third game.
It has been a hot week the first week but thankfully I have had easy matches going through without too many long four or five setters
Federer will next face Spanish 20th seed Roberto Bautista Agut for a place in the quarter-finals.
“I am very happy. It has been a hot week the first week but thankfully I have had easy matches going through without too many long four or five setters,” said Federer. “Now there are only big matches.”
Dreadlocked German qualifier Brown was unable to follow his triumph over Nadal when he slumped to a 6-4, 7-6 (7-3), 4-6, 6-3 defeat to Serbian 22nd seed Viktor Troicki.
Brown joins Lukas Rosol, Steve Darcis and Nick Kyrgios who all lost their next match at Wimbledon after knocking out Nadal over the last four years.
Troicki goes on to face either British wildcard James Ward or Canada’s Vasek Pospisil for a place in the quarter-finals.
