I am watching it now. nadal is shaky as hell.
especially off the backhand wing. there is no consistency.
he is returning ok but not great. he could have some issues with his return tomorrow as wawrinka has been hitting serves in the 128-138 MPH range.
wawrinka is also crushing the ball off the ground. the average speed of his strokes yesterday was 80 MPH.
I think nadal is running on fumes right now. he is tired from having won so much. there is mental fatigue and then there is physical fatigue.
