Britain's Kyle Edmund watched his opponent concede a match for the second time in a month after Adrian Mannarino handed him a 6-3 6-0 victory at the Delray Beach Open.
Mannarino was penalised a game for smashing a ball out of the court in anger and, as Edmund led 6-3 5-0 and 15-0 in the sixth game of the second set, the punishment confirmed the Frenchman's defeat.
It was the last of three unsavoury incidents in the contest as a frustrated Mannarino had earlier kicked a chair midway through the second set before hitting a ball in the direction of a ball-boy.
In the final game, with Edmund serving, Mannarino then slammed two consecutive returns out of the court and was handed the decisive game penalty.
Edmund was already in a commanding position, just as he was when a similar incident occurred two weeks ago against Denis Shapovalov in the Davis Cup.
Shapovalov was defaulted for blasting a ball out of court and into the eye of umpire Arnaud Gabas, with Edmund leading the Canadian 6-3 6-4 2-1.
The British number three's win over world number 60 Mannarino means he will now face either Taiwan's Yen-Hsun Lu or American wildcard Bjorn Fratangelo in the second round.
