Australian bad boy Nick Kyrgios is facing heavy sanctions after an explosive meltdown at the Cincinnati Masters today.
The 24-year-old took aim at chair umpire Fergus Murphy, claiming he was unfairly calling him for a slow service game.
Kyrgios carried out constant verbal abuse against the Irishman, calling him a potato and the worst umpire in the world.
The Aussie followed that up by taking a toilet break despite Murphy declining his request and subsequently smashing two racquets in a tantrum in the tunnel captured by cameras.
Ironically, it was a double fault from Kyrgios handing Russian eighth seed Karen Khachenov the match.
Kyrgios marking the end of the match by calling Murphy a “f------ tool” and spitting as he headed the chair umpire's way.
Kyrgios is still expected to be seeded for the US Open in just under a fortnight, although he's likely to cop some serious fines.
