Fans on social media weren't too impressed either, with some saying it wasn't in the spirit of the sport.
"If the @PSAWorldTour let Asal get away without a fine then there isn't a hope for Squash," one fan wrote on Twitter. "Absolutely ridiculous. Very sad to see it."
Others questioned the safety of Asal's actions during a pandemic: "Should he be tossing a sweaty shirt & wristband into the crowd...during a pandemic?"
Asal was almost left embarrassed as officials reviewed a possible obstruction on Coll, but the point ultimately stood, with the Kiwi just missing out on progressing to the next round.
Earlier in the week, fellow Kiwi Joelle King lost in her third-round matchup against Salma Hany 6-11, 9-11, 11-9, 11-8, 11-7.
It was yet another feisty affair, with both players even exchanging strong words during the match.
But Hany was able to come back from losing the opening two games to move on to the next round.
