World Number One Jannik Sinner meets former champion Daniil Medvedev at Arthur Ashe Stadium

Daniil is beginning to shift more of the rallies his way and there are sure signs he is settling into the task when he gallops to his right to pick-up a crosscourt volley and earn the block to open court that allows him to attack with a backhand passport.

Sinner wobbles from there with a forehand that slaps the tape and a double fault.

Medvedev drags a backhand long on the first of two break points and then watches in horror as a volley lands just wide following an eye-catching exchange.

The top seed continues his revival from deuce with a smash and drive volley ensuring he maintains his advantage.
