It looked like it hit something to me and it wasn't batYeah the 4th wicket was definitely out, he walked across his stumps and would have hit middle-leg.
But that hat trick ball, at the absolute worst it hit his glove, and possibly didn't hit anything. Certainly didn't hit his pads. But I guess that's BBL umpiring for you.
WTF was Hussey thinking when he looked at the replay and said "I think that's actually a pretty good decision"????
