Jack Sock's playing a serious game out there as he thumps the ball towards Federer, who can only knock the ball down in front of him.
But there's the Federer of old, stretching to screw a forehand across the court and the great man lets out a big roar for that one.

Fedal - and their supporters - need a second wind before the match tie-break.
