Actually you'll find Rafa won most of his slams in intense pain. He's spoken about it regularly. He said he enjoys the pain and its challenge. 2009 Australin Open is the best example. He was still in shreds from 2008. But in 2012 it was announced by Uncle Toni that there will be 'no more bandaid solutions'. That means no more playing in pain. If Rafa used the old approach he would have played the Olympics and the US Open this year. Now he is planning on 2016, so he knows he can't afford to play in pain. He'll play Roland Garros at 100% in 2013, because he won't take unnecessary risks at Miami.
