Novak Djokovic *3-3 Daniil Medvedev
A quick hold to 15 for Medvedev. At 15-15, he demonstrated his ability to flip defence into attack so seamlessly, injecting pace into a forehand down the line and surprising Djokovic. At 30-15, he slammed down an unreturned serve. He closed off the game with a quick serve and backhand 1-2 combination. He is serving pretty well so far. 8.36pm GMT

A much easier hold from Djokovic, who moves back ahead with more industrious play. At 15-0, he played the most gorgeous drop volley and then he closed off the game with an unreturned serve.
