EDIT/UPDATE: It’s come to my attention that the diagram below isn’t exactly what it seems. Contributing writer and PitchF/x guru Will Moller will be issuing an updated evaluation of Pettitte’s strike zone and the mistake he caught. Good stuff, trust me. Keeping us all honest, one blog at a time!

My only question for Jay is:
Was the umpire consistently bad or was Pettitte the beneficiary?
