All tournament he was intentionally pattern racking. On at least 80% of racks he'd have the 2, 3 all up top, once in a while he'd vary it by putting the 2 or 3 as a wing ball, but essentially he was setting up the rack so he'd have a strong chance at a combination on the 9, without having to shoot even half a rack, which he did multiple times against Orcollo alone. He's also been warned in other tournaments about twisting 8-ball racks to wire a wing ball. Sad really, because he has the skill not to need to resort to these sorts of things.
OK, I just don't see pattern racking the same as rack rigging. To me, rack rigging is leaving gaps and tilting the rack.
