According to Wikipedia, Fed has a win loss record in his career of
1161-W /254-L. I dunno, one would think Federer has a lot more muscle memory of winning and pulling out of tough scrapes
Again up to this Wimbledon here are Roger's MP's lost matches...
https://www.theguardian.com/sport/2008/jul/06/wimbledon.tennis8
So the Djokovic/Federer 5 sets matches in back to back USO SF's in 2101/11 Novak had MP's in the FIFTH set. The Rafa/Federer Italian Open Roger had MP's in the FIFTH set. The Safin/Federer AO SF in 2005 Federer had MP on Safin in a FOURTH set tiebreaker. ETA: Haas saved MP's in 5th set at 2002 AO.
So isn't this the first time that Federer has lost a 5 set match where he was 2 setsup AND had MP's in the 3rd set? Where is the muscle memory for that precise scenario previously?
Now an interesting stat would be how many matches have the top players won or lost when they had MP's in a single game and then failed to close it out in that particular game but then went on to win the match.
Another stat would be how many 2-0 set leads did Federer go on to win, I would venture to guess a TON. Didn't he have 4 straight set wins over opponents in this Wimbledon alone before the quarters. That's alot of good memories fresh in the noggin.
Another stat would be how many times has Federer been up 2-0, lost the 3rd set and then went on to win in 4 sets?? I'm guessing ALOT of matches...So even losing the 3rd set to KA, he still had 2 sets to close it out as he had done previously.
Where is the muscle memories of all those wins??
Where is the muscle memory of beating Kevin Anderson 4 straight matches and not even losing a set, so he loses a set and suddenly it's preordained he's going to lose because all his previous losses in his career crowd out any other thoughts??
C'mmon. ; )
