Monte Carlo, Principality of Monaco: Daniil Medvedev launched into another angry tirade against the officiating at the Monte Carlo Masters on Thursday as he was beaten 6-3, 7-5 in the third round by Karen Khachanov.

Medvedev was hit with a point penalty to start the final game after berating chair umpire Carlos Bernardes and then became embroiled in a heated discussion with the tournament supervisor.

The world number four had already been warned after hurling his racquet when he double-faulted to lose his service game and leave Khachanov a game away from victory.

Medvedev, who took issue with two line calls in his second-round win on Wednesday, felt aggrieved a Khachanov forehand was not called out during a rally that resulted in the latter earning two break points at 5-5.

The arrival of the physio to treat an apparent bleed at the ensuing changeover tipped Medvedev over the edge, with the Russian yelling "did I ask for the physio!" at the umpire.
