Perth Wildcats coach Trevor Gleeson has accused NBL referees of applying double standards in their officiating of Perth's Casey Prather and Adelaide rival Jerome Randle, after Thursday's 78-74 loss to the 36ers.
Prather shot just four free-throws for the evening, while Randle shot 11 and made eight of his 17 points at the charity stripe.
And he wasn't even Adelaide's most prolific free-throw shooter - fellow guard Nathan Sobey made 11 of 12 from the stripe, nearly scoring half of his 24 points there.
The defending Australian NBL champions were whistled for 30 fouls to the Sixers' 19 and subsequently attempted 20 less free throws.
Gleeson was particularly angered with a charge called against Prather early in the fourth quarter and a non-call, when the athletic swingman crashed to the floor inside the final minute, but Gleeson said asking the league for an explanation was a waste of breath.
