Old Federer out grind Nadal from the baseline at the AO in 2017.
Yep, Federer won the longest rally of the match, somewhere in the 5th! I just rewatched that set yesterday!
What struck me was the symmetry and anti-symmetry between the 5th sets of that match, '17 AO F, and the '19 Wimbledon F.
The symmetry is: In '17, Nadal was a break up early, but Federer broke back twice and served for the championship at 5-3. In '19, Djokovic was a break up early, but Federer broke back twice and served for the championship at 8-7.
The anti-symmetry is: At 5-3, Nadal had 2 break points, but ultimately lost the game and championship. At 8-7, Djokovic had 2 match points against, but ultimately won the game and championship.
So the clutch-ness ranking has to be Djokovic >> Federer >> Nadal.
