Frenchman Benoit Paire lost the plot in a big way during his ASB Classic semi final on Friday night.
After taking the first set against sixth seed Hubert Hurkacz, the world No 24 Paire seemed to be increasingly frustrated with spectators talking during points.
This reached a spectacular climax during the second set tiebreak, when Paire was distracted by a male fan in the Robinson Stand, frequently yelling "Come on Benny" in a sarcastic manner, just as he was about to serve.
The player stopped in the middle of his serving motion, and walked to the far corner, then addressed the umpire.
