Zverev, Schwartzman battle in first match of the day
Head-to-head
Medvedev on the board
Djokovic off to a flyer
Welcome!
My name is John Lupo and I will be your host for this key matchup.

A final hold caps a brilliant effort from the fourth seed as he took command of this match from 3-2 down, ripping off seven games in a row and dictating in all areas. A well-deserved semifinal berth for Medvedev.
Djokovic didn't play his best, but he was beaten by the better man on the day. He'll face Alexander Zverev on Friday for a semifinal spot and based on today's performance, he'll need to be a lot better to take out the German.
This is John Lupo saying thanks for joining me and stay tuned for more coverage of the ATP Finals and join me again tomorrow as Dominic Thiem takes on Andrey Rublev.
So long for now.
