Roger Federer:

Roger Federer on Monday extended his dominance against Bulgarian Grigor Dimitrov, beating him 6-4, 6-2, 6-4 in a fourth round encounter to move into his 15th Wimbledon quarter-final.

The News Agency of Nigeria (NAN) reports that the seven-time champion now stands alone atop the Open Era list for most Wimbledon quarter-final appearances.

The 35-year-old advances to his 50th Grand Slam quarter-final, another best in the Open Era, and is now 6-0 against Dimitrov in their FedEx ATP Head2Head series.

The Swiss right-hander has won all but two of the 16 sets they have played since their first meeting at the 2013 Swiss Indoors Basel.

Dimitrov had not dropped a set during his first three Wimbledon matches and the 2014 Wimbledon semi-finalist had looked primed to challenge Federer.

But the third seed was nearly untouchable in the familiar Centre Court environment.

The two exchanged holds until 4-4 in the first set, when Federer stepped up to break for a 5-4 lead and then serve the set out to love.

Federer quickly pounced in the second set, seeing two break points at 2-2 after Dimitrov double faulted.

The 26-year-old Bulgarian finished with seven double faults for the match, compared to seven aces.

And Federer would need only one break point in that fifth game, converting it when Dimitrov slapped a forehand wide as he struggled to challenge Federer in his service games.

At 6-4, 4-2, Federer’s average service game was lasting only one minute and 21 seconds.

For the match, the Swiss right-hander landed 70 per cent of his first serves and won 75 per cent of his service points.

The third-seeded Federer has yet to drop a set this fortnight, and will face either 2016 finalist Milos Raonic or German Alexander Zverev in the quarter-finals.

Raonic beat Federer in last year’s semi-finals to reach his maiden Grand Slam title match.
