[Rain Man]

It really looks like a hold on the field, but if you look at the other angle, you can see that the defender's problem is that he got his left arm caught between Donovan's right arm and ribs. Donovan just clamped down and got the defender in an arm bar without holding him. The defender had no leverage and Donovan can lift a horse, so once that happened the defender was screwed. Donovan didn't even need to use his hands at that point, and the defender couldn't get away. So I wonder if the ref astutely saw that and recognized that it's not a hold even though it looks like there's holding.
