Andy Murray exited the Miami Open at the third round on Sunday after defeat to Grigor Dimitrov.
Murray had won the opening set but then went 3-0 down in the second.
His frustration at having his serve broken was obvious.
With the camera trained on his Bulgarian opponent, Murray could be heard smashing his racket against his bag. The camera then switched to the Scot as he continued to vent his frustration - eight times in total.
The incident resulted in a violation for Murray, much to his surprise and also the commentators.
