I still rate Dreckman the worst, then Laz "Strike Zone du Pitch" Diaz, and Gordon. Hernandez is at least consistent with a bad zone, the others you never know since they are so inconsistent. Hernandez was a crappy HS ump down here, and hasn't improved. I have no idea how a guy with such bad fundamentals became an MLB ump.
Dreckman - the name says it all. Next umpiring crew will feature Blindsie, and Inconsistento.
