Djokovic 6-7 (4-7) 5-5 Chung*
Now the pressure is on Djokovic.
Chung just tickles a backhand over the net, it throws Djokovic off slightly and he can't muster the composure to muster a meaningful response.
That's better. Punchy groundstrokes leading to a ferocious forehand winner, and Djokovic holds.
