The on-court "circus" between Nick Kyrgios and Stefanos Tsitsipas spilled into the Wimbledon media interview room as the Australian denied his opponent's claim that he was "a bully" who could be "evil".
A combustible atmosphere saw Tsitsipas aim several shots at his former doubles partner and also receive a warning for hitting a ball into the crowd and nearly striking a spectator.
Kyrgios, 27, insisted his opponent should have been defaulted for the incident, claiming the ball hit the fan on the head, although television replays suggested otherwise.
Tsitsipas had started to lose his cool towards the end of the second set after Kyrgios repeatedly berated chair umpire Damien Dumusois.
