Now the 32-year-old South African moves on to a semifinal against No. 9 John Isner of the US or No. 13 Milos Raonic of Canada. Then he showed that he is top 30 after all, he played two good sets after that.
'Today was one of those days. You have to have that mindset. "I feel like the more experienced you are, the more you can deal with those better". "Matches likes that are very special".
The 20-time Grand Slam victor is aiming for a 13th Wimbledon semi-final and to extend his record for the most last four appearance at the All England Club in the Open Era, having taken sole ownership of the record from American Jimmy Connors during his 2017 title run.
Djokovic also advanced to his first Grand Slam semifinal since 2016, shrugging off a second-set slump to beat Kei Nishikori 6-3, 3-6, 6-2, 6-2. Not only is Federer the best of all time on the Wimbledon grass, and not only is Anderson historically not great on the grass (he's never been to the quarterfinals at Wimbledon before this year), but the 32-year-old South African has never won a set off Fed-Ex anywhere.
The first set between Federer and Mannarino was so one-sided that, when Mannarino trailed 0-40 in the opening game of the second, the normally pro-Federer Centre Court crowd began to cheer loudly for his opponent. The final game was an extensive nail-biter, with Anderson ultimately winning out 13-11.
Deploying his huge serve to lethal effect, Anderson roared back to leave the champion's title bid in tatters thanks to a barrage of 28 aces and 65 winners.
Anderson, meanwhile, eventually overcame Monfils 7-6 (7/4) 7-6 (7/2) 5-7 7-6 (7/4) to set up a clash with Federer.
Anderson is the first South African man in the Wimbledon last-eight since Wayne Ferreira in 1994.
Djokovic looked in control in the first set.
Federer responded, quickly breaking back before taking the set in a tie-break.
Switzerland's Roger Federer leaves court after losing to South Africa's Kevin Anderson 2-6, 6-7, 7-5, 6-4, 13-11 in their men's singles quarter-finals match on the ninth day of the 2018 Wimbledon Championships at The All England Lawn Tennis Club in Wimbledon, southwest London, on July 11, 2018. Anderson held for 5-all, broke to 6-5 with a violent return victor off a 97 miles per hour second serve, then staved off three break points and closed the set with a 133 miles per hour ace.
Federer and Nadal are favourites to meet in Sunday's final - 10 years after their epic 2008 showdown - but Wilander believes Del Potro could throw a spanner in the works.
A double fault gave Anderson a break point, Federer then firing into the net, and his hopes of a record-extending ninth Wimbledon title were ended as he was unable to return a huge serve down the middle.
