Nadal at USO 08 and Tokyo 11. First two sets of AO 2010 also.
Raonic at USO 12.
The whole Olympic run
Tsonga at Wimby 12
Toronto 2010, against Nalbandian, Nadal and Federer he played superbly in all of them.
An honourable mention to AO 07 4th round against Nadal, that was the first time I honestly thought- going to the very top. Also Djokovic at the AO 2012 semis despite losing he was outstanding for long periods and was highly unfortunate not to win it, was a point from serving for it.
Having seen 95% of his matches since his debut v Hernych in Barcelona 05 I feel qualified enough to judge.
if you've truly watched his hundreds of matches since then I applaud you for being able to sit through a lot of shit fests and the occasionally gem.
also you must have a massive amount of free time, even I with a relatively free schedule can't manage to watch all of my favorites play live year long, do you record a lot of them?
