Federer trolled and got into Murray's head (Murray's biggest enemy) and it won him this set. But will it win him this match? I still doubt it...not the way he's been dominated throughout. But I guess I shouldn't downplay the possibility of a Murray choke.
Lol at the time Murray is taking between serves, he is nervous as hell. Commentators are such fedtards it's annoying, When Murray hits an amazing shot good shot when Federer does the same wow amazing shot.
