Djokovic evens it up with Federer at a set apiece

And the second set wasn't even competitive -- Djokovic took advantage of several uncharacteristically sloppy shots by Federer for a pair of service breaks and a 6-1 second set.

Djokovic has now broken Federer three times in these two sets; Federer had been broken five times in his first five matches combined.

Djokovic has the momentum now heading into the pivotal third set.
