Benoit Paire was at the centre of remarkable, yet ugly, scenes on Thursday as he indignantly crashed out of the Argentina Open.
The fiery Frenchman was the third seed and all appeared to be going relatively well against world number 137 Francisco Cerundolo.
He took the first set, but completely lost his composure over a disputed line-call early in the second set.
The Argentinian Open, like most clay events, does not use Hawk-Eye live, instead relying on marks on the court to settle disputed calls.
And when the umpire did not rule in favour of Paire, he responded by spitting on the mark on the court.
He received a code violation, but he wasn't done there. Paire slowly lost control of the match, and literally threw it away in the final stages.
Serving at 1-5 down in the final set, he opted to tank and served a series of deliberate double faults.

It is sure to see him receive some hefty fines from the ATP, who will understandably take a dim view of his behaviour.
His apparent lack of remorse is also unlikely to do him any favours eithers, with him tweeting a photo of his career prize money earnings after the match alongside the words 'sometimes it's useful to be useless.'
