I am watching the Rangers playing the Mariners right now, and I saw the strangest mechanic I have seen in a while, even in MLB. PU is a pointer on his strike calls. Batter attempted to check swing with two strikes, but failed to do so in the PU's judgment. PU points at batter with left hand, then raises right hand with index finger pointing to the sky, and twirls the finger in a circular motion. Just thought I'd share!
