Juan Martin Del Potro is a good clay court player

Time and again People completely forget one major thing, Juan Martin Del Potro is from Argentina, which breeds clay-courters, Even-though Del Potro prefers Hard courts due to his style of play, he is well used to clay courts more than Hardcourts,

Rafa without doubt is the favorite but to say he will 99 out of 100 times is really silly, he has lost to Soderling last FO, what's soderling - Nadal percentage now in FO ?

For your notice, Del Potro Rafa encounter in RG was a close affair in the first set at 7-5, that Del Potro was not even half good as the current version is.

So its not myth that Del Potro is good at clay as he is quite used to clay from his childhood days.

Del Boy will struggle on grass and Wimbledon without a doubt is much harder slam to achieve than RG , this is down to the simple fact of his movement in grass, do you see how many guys slip in grass, last year Wimbledon was just a prime example.

TO think Murray is bad on grass is absurd again, its just Roddick's game and experience proved crucial on winning last year's Semi against Murray, that doesn't make Murray a bad grass court player eventhough I won't name him as exceptional grass court player.

Nole in grass is mystery, he could end up like Safin or he might even conquer it many times,we have to wait and see.
