So far in his illustrious career so far he has claimed retirements over high caliber players at three of the slams. * FO retirement against Nadal in 2006. * Wimbledon retirement against Nadal in 2007. * AO retirement against Roddick in 2009. Yet has only claimed 2 slam titles so far in his carrer. Which historical milestone will he get to first? He has a chance in the next couple of years to achieve both and he would be the only man to do this!
