The German is a two-time Grand Slam victor and the top ranked player in the draw, with Muguruza the French Open victor from past year. "It appears that they have more time to think".
American Sam Querrey needed only four minutes to break serve and wrap up a 6-2 3-6 7-6 (7-5) 1-6 7-5 win over French 12th seed Jo-Wilfried Tsonga. "The first match with the walkover saved me a lot of energy, crucial energy".
All 16 fourth-round singles matches are scheduled for Monday - Wimbledon is the only major that does it that way - including these in the bottom half of the men's draw: No. 3 Roger Federer vs.
Mattek-Sands says on Facebook Live that "it's been an emotional and painful roller-coaster the past few days". - Bethanie Mattek-Sands, speaking from hospital, reveals she ruptured the patella in her right knee in Thursday's sickening accident. "I freaked out. It's the most painful injury I have ever had".
From the second set on, Federer was in complete control.
"Because we have daily monitoring, we can keep a very tight rein on everything", he said. Nadal may be playing well this time around, but he is not the same player at Wimbledon that he is in Paris, and Murray will come through to reach the final match.
The Australian Open champion was up 4-2, 30-love when Zverev responded winning eight of the next points to level. The standard at which they played ensured their unforced errors remained a staggering nine and seven respectively.
Muguruza set the smoke alarms wailing for a good 20 minutes at her rented house after burning some steaks - and feared the fire brigade would turn up to tell her off. "But I managed to hang on with him and play a very good tiebreak".
Victory for Federer sets up a fourth-round clash with Grigor Dimitrov, who was two sets up on Dudi Sela when the Israeli - beaten 6-1 in both - retired hurt. It was also avoidable not to be broken in the first set, but then I had to hang on to it with being down one breakpoint or two breakpoints maybe at 5-All in the first set.
The first Saturday at Wimbledon, as per tradition, has plenty of sports celebrities in the Royal Box.
But he'd prefer to play better on Centre Court tomorrow than he did that day. Garcia was wearing his green jacket from the Masters.
Asserting his all-court attack, Federer dismissed Mischa Zverev, 7-6 (3), 6-4, 6-4, flying into the Wimbledon round of 16 for the 15th time.
Yet years ago, Mischa's career looked nearly as promising the young Sascha's has become: He reached 45 in the rankings at the age of 21 before a wrist injury saw him sink outside the top 1,000 in 2015 and barely climb inside the top 200 18 months ago. Back in 1984, it was Tim and Tom Gullickson. On Saturday, he made it past the 27th-seeded Mischa Zverev without much issue, and punched his ticket into the fourth round.
The 18-time Grand Slam victor finished with 58 winners and just seven unforced errors.
Meanwhile, there were wins for Milos Raonic, Dominic Thiem and Tomas Berdych, all of whom will have designs on going deep into the tournament. Venus Williams, at 37, is the oldest woman left in the women's draw and as she chases a sixth Wimbledon title, she is also the only former victor left in the fray.
