its fake can tell by the shadows,,
He is right, it look fakehe is moving his hands just like he would normally when not spinning the bat, also it is moving way to fast for the amount of power he is giving it.
Look closely. Just before he throw bat, his hands moves back to spin it. And because of bat's center of gravity shifted toward thick part, handle move faster.I wouldnt call it "crazy skill", by the way. Just need some practice, like most tricks.
