Federer has OWNED this sport. I'm a big Sampras fan, I used to cheer against Federer whenever he plays just because he was close to equaling Sampras records. Now, He overpassed Sampras by a mile and I've seen enough of him playing wonderful Tennis that converted me to be a huge Federer fan since 2007.
Great personality as well. If you have followed him throughout his career, you'll certainly admire the man. I'm curious to see when will this amazing run ends. It'll be a sad day watching him leaving Tennis.
