I don't know where MLB gets them but they keep popping up. Last night's Yanks game typified poor calls. A rookie umpire tossing a player without even looking to see who complained, picking one he "thought" was the culprit? Another bad ruling on a legit infield hit? I really believe they should institute computer balls and strikes, and put umpires like Angel Hernandez and Joe West out of business. I've seen too many calls where they think Aaron Judge and Jose Altuve have the same strike zone.
