I don't think it's such a dramatic situation given that he managed to tough it out against Delpo who was playing well but you never know with these things.
Yeah. In all seriousness, these guys have abnormal pain tolerance and insanely short recovery times.
That's why Delpo was able to continue with the hip twist, even though it was clear that it was inhibiting his movement.
Ditto for Nadal who was whaling away at the ball after set 1, because he wanted to cut the pts short and not run. I also felt that he was a little subdued given how tense the match was. Didn't show too much positive energy out there. Had he lost the 1st set, I think the match would've been over.
Adrenalin can make you survive in a match and Nadal said he still felt pain. We'll know tomorrow about him, but it doesn't look too good.
Reg Delpo: ATP Beware! When this guy comes back 100%. everyone else can forget about winning slams. This is supposedly his WORST surface, and IMO he would have taken out anyone today except Fed or Nadal..
