2007 was around the time Nadal began to show he was more than just a clay court specialist. Wimbledon 2007 Federer was at one stage two rounds ahead of Nadal (a rare event in a slam). Federer got a fourth round walkover from Tommy Haas, putting Fed into the quarters, while Nadal was still in the third round trying to finish his match with Robin Soderling. Playing day after day took its toll on Nadal (he had treatment on court towards the end of the final). Nadal lost the 2007 Wimbledon final, but Federer was right, Nadal had improved.
Reached the final on Miami 2005 and Wimbeldon 2006 and he played one of his best indoor matches in YEC 2006 vs a Federer in a straight sets loss.
