Trailing Kyle Edmund 6-3 6-4 2-1 in a crucial decider between Great Britain and Canada in the Davis Cup, Denis Shapovalov let his frustration get the better of him; slamming a ball into the umpire's face with the kind of accuracy he wishes he had during the actual match.
Let's take one more look at that...
Not typically known as a dangerous job, the umpire Arnaud Gabas will be cursing the luck that lead to him taking the full brunt of Shapovalov's ire after the young Canadian dragged another backhand wide.
Having been automatically disqualified from the match and thus handing the win to Great Britain, who will go on to face France in the next round, Shapovalov apologised for his actions.
"Luckily he was OK but obviously it's unacceptable behaviour from me," said Wimbledon junior champion.
"I just feel awful for letting my team down, for letting my country down, for acting in a way that I would never want to act.
"I can promise that's the last time I will do anything like that. I'm going to learn from this and try to move past it."
The Frenchman, who took the hit like a champ, headed to Ottawa General Hospital for a precautionary evaluation on bruising and swelling to his left eye after the incident, and is expected to make a full recovery.
