With a seemingly large amount of avid tennis fans who frequent this site, I'm surprised this thread was not created. Right now it's Isner (his first ever major semifinal) versus Anderson. It has been a great match thus far, as the first set went into a tie break. After this will be an epic match between Nadal and Djokovic. Federer's match the other day was fantastic and I'm surprised he lost. He had match point in set three, but lost in five sets.
