Entering Friday's semifinal, the 17-time Grand Slam champ is the only top-five seed remaining in the tournament and he is six years older than Berdych, the next-oldest semifinalist.
Despite undergoing arthroscopic knee surgery in February, the first major surgical procedural of his career, and dealing with lower back pain, Federer insisted on making the trip to Paris to extend his record of playing in 65 consecutive Grand Slam events. I don't feel ready to go.
Roger Federer is in the Wimbledon semifinals for the 12th time.
"The body didn't really allow me to play, in my opinion".
Roger Federer's quarter-final fixture would be Wednesday's second match on Centre Court.
"Then the matches, I could never really play quite so freely past year just because, you know, I'm more focused on how the knee's behaving rather than how I need to hit my forehand or backhand, or what's not going to be good for my opponent". Federer, the pre-tournament favourite, is just three wins away from winning an unprecedented seventh Wimbledon title.
Federer walked out on Centre Court after Murray's shock defeat to Sam Querrey and then saw it announced on screen that Djokovic had retired injured from his match against Tomas Berdych.

According to a series description, a "bigger, sinister entity still threatens those who survived" in the first season. Hopefully, with a poster release like this, a new trailer - maybe featuring Eleven - can't be far behind.
Raonic might have had the 140 miles per hour serve in his locker, but Federer owns a magic wand that he used to make the world's sixth best player look like a lumbering also-ran.
With Djokovic citing an elbow injury that's plagued him for more than a year and Murray struggling through hip pain, should the case, then, be made for both players to take much-needed timeouts of their own?
Federer has already trimmed back his schedule, skipping the 2016 and 2017 French Opens which were won by Djokovic and Nadal.
Federer came out sharp early as he handled Raonic's big serve easily. "Sometimes the body and the mind do need a rest".
"I hope that Novak is ok with his injury". I'm just very happy that I'm still doing so well. "It's always calibrating the whole thing".
"I think the most significant thing is he's mentally sharper and I think he's moving better", Raonic added.
The Swiss ace, who is yet to drop a set, won the first two sets in 57 minutes.
