Wimbledon 2015: Roger Federer strolls on but Djokovic left in a sweat
Roger Federer made smooth progress through to a 13th Wimbledon quarter-final as he brushed aside the challenge of Roberto Bautista Agut.
Spaniard Bautista Agut was playing in the fourth round at the All England Club for the first time and was overwhelmed on Centre Court by the seven-time champion.
Swiss second seed Federer eased through 6-2 6-2 6-3 and will tackle Gilles Simon in the last eight tomorrow.
Federer felt he had played well, but played down the suggestion his display was a statement.
"I don't think I made a statement. It was nice to play a baseliner after two big servers," Federer said. "I did a nice job making the transition.
"It was a good match. I got off to a good start and kept rolling. Obviously maybe Roberto wasn't at his very best."
Bautista Agut had an injury break during the second set but carried on.
"I had to put him away, which I was able to do so," Federer said.
"I'm happy to be back in the quarters here. This is really when it gets much more interesting, when you can look ahead a little bit without doing that too much because obviously your opponents are going to get tougher and tougher.
"I'm not going to look further than Gilles Simon who has caused me difficulties in the past. I played him tough in some of the majors, Australia, French Open, we played five sets both times there."
Federer broke his Spanish opponent in the fifth game of the first set and again in the seventh to win it in 19 minutes.
The 33-year-old broke again in the first game of the second set before Bautista Agut called for the trainer, having hurt his ankle sliding beyond the baseline.
Federer then attacked the Spaniard's serve early in the third to close the contest in one hour 26 minutes and move closer to a possible semi-final meeting with Andy Murray.
Meanwhile, defending champion Novak Djokovic was tied at two sets all with big-serving South African Kevin Anderson when fading light brought their match to a halt on Court One.
Anderson had taken the first two sets on tie-breaks, setting up the possibility of a major upset, before improving Djokovic battled back to make the match scoreline 6-7 (6/8) 6-7 (6/8) 6-1 6-4 overnight.
Tournament officials ruled out the prospect of moving the match to finish on Centre Court, where lighting allows matches to continue until an 11pm curfew.
Although the match between Gilles Simon and Gael Monfils was moved to complete on the main show court on Saturday night, a tournament spokesperson said that was because of Sunday's rest day, and the urgency to avoid the match being held over to Monday.
Jamie Murray joined brother Andy as a Wimbledon winner on Monday as the Scot and Australian partner John Peers sent the defending doubles champions crashing out of Wimbledon.
A marathon match on Court 12 ended in Murray and Peers triumphing 6-3 7-6 (8/6) 6-7 (5/7) 3-6 8-6 against American Jack Sock and Canadian Vasek Pospisil. Jamie Murray, now 29, won the mixed doubles title with Jelena Jankovic in 2007.
Britain's Jonny Marray won the Wimbledon men's doubles with Danish partner Freddie Nielsen in 2012, but their run this year came to an end at the hands of second seeds Ivan Dodig and Marcelo Melo. The Croatian-Brazilian partnership proved too strong for Marray and Nielsen, who lost 6-1 6-4 7-6 (8/6) in an hour and 20 minutes.
