Federer said that two hours later, watching the World Cup was where he wanted to be -- as Switzerland played Argentina in a round-of-16 match. Even with Lionel Messi opposing his favorite squad, Federer said he was optimistic.
"That's why we love sports, why we watch," Federer said. "You don't know what's going to happen."
The win was Federer's 71st at Wimbledon, moving him into a second-place tie with Boris Becker on the all-time list. Jimmy Connors is first, with 84.
Oh, Canada again
In the very first game, Nishikori actually broke Raonic, converting his sixth break opportunity. It was the first time Raonic's serve was broken in this tournament. And then ... nothing.
Raonic served the 24-year-old Japanese player off the court and wound up winning 4-6, 6-1, 7-6 (4), 6-3. He finished with 35 aces -- his fastest serve checked in at 141 miles per hour -- and 66 winners.
Nishikori admitted there wasn't much he could do with Raonic's serve.
"Not really," he said. "Yeah, that was the key of the game today. He was hitting good serves and too many aces. Mostly I have to guess because he has great both serves, first and second. He can hit spin sometimes the first and second serve.
"I tried everything, but I couldn't read his serve."
And so Raonic, 23, follows fellow Canadian Eugenie Bouchard into the quarterfinals at Wimbledon. He's only the second Canadian to reach that stage in Wimbledon's 128 years. And it happened on Canada Day.
Raonic politely said he wouldn't be doing any celebrating.
"It's a quick turnaround," Raonic said. "Unfortunately, to this point there hasn't been as much Canadian success, especially on the singles side in the men's. So all the things sort of come and go and you appreciate them, but you don't give them too much value because it's ambitions that are beyond doing what no Canadian has done before.
"It's about really trying to become the best player in the world."
Defending champions Bob and Mike Bryan found their way back into the quarterfinals with a convincing 7-5, 6-3, 7-6 (5) win over Juan Sebastian Cabal and Marcin Matkowski. The Americans will meet Julian Knowle and Marcelo Melo, who defeated Chris Guccione and Lleyton Hewitt in four sets ... Francis Tiafoe, the 16-year-old junior from the Washington, D.C. area, had never played on grass until about two weeks ago when he practiced at the Roehampton facility adjacent to Wimbledon. It didn't stop him from winning his first-round match, which carried over from Monday. Tiafoe, the No. 2-ranked junior in the world, defeated Martin Blasko of Slovakia 6-4, 3-6, 6-3.
