DJOKOVIC 5-2 MEDVEDEV: Djokovic is going after the Medvedev backhand and is having some success.

DJOKOVIC 3-2 MEDVEDEV: There's a sharp intake of breath as Djokovic returns into the net two points in succession, giving Medvedev break point. He saves it with a tremendous rally, coming into the net to volley it short, and eventually takes the game with an ace.

DJOKOVIC 2-1 MEDVEDEV: The umpire replaces his microphone and gets an ovation for having an amplified voice. Hold to love for Djokovic.

Oh, the chair umpire doesn't have a working microphone, and he's just shouting. Hilarity ensues.
