Remember Nadal destroying him in IW 2009 in super windy conditions. In such conditions, the ability to keep the ball in play becomes absolutely essential, but also the ability to push with power (or in Nadal's case extreme topspin) is even more important.
I think JMDP would have loved those windy conditions, he'd have been unable to unleash his powerful yet safe shots and the conditions would have made it almost impossible to outmanouever him. Federer would have loved them even more, bet he'd have straight setted both Murray and Nole had he beaten Tomas.
Thanks for the reply.
