Incredible running and shot making from Nadal to hold.
Now, I'm not saying I think any of this will happen, this is just speculation:
I wonder, if this match continues to go on and on, how long will it be before they place Ferrer/Tsonga on SL in order to try to get both matches done tonight? Or will they do that, or simply put Ferrer/Tsonga on the court tomorrow? And if they do make them play tomorrow, will they still hold the final on Sunday?
