not how I remember the 4th set and TA point by point backs me up:.
Federer lost 1 point on serve in his 1st 4 service games. djoko lost 6. Given the way the set was going, it looked to be going to a TB without any breaks.
Fed holds at love
Djoko holds at 30
fed holds at 15
djoko holds at 15
fed holds at love
djoko holds at 30 after being down 0-30
fed holds at love
djoko holds at 15
then long game where djoko breaks
federer breaks back with a great game
point is both were red-hot.
stan didn't play well in the 1st set.
Not sure if djoko would be able to take a red hot stan like delpo of the 2nd set to a TB (TB was one where delpo faltered in the whole of 1st 3 sets. fed couldn't even break him till the start of the 4th set)
