I'm missing stats from a few years here but here's 14 years since 2000 from what most would consider to be an Over ump in McClellland and an Under ump in Eddings. McClelland year after year after year calls less strikes than Eddings does which leads to more runs per game. Notice not one of these years did McClelland call more than 63% strikes while not one of these years did Eddings call less than 63% strikes. Umpires do not have the same zones, they do not call pitches the same, this is not disputable, doesn't matter if you were a former umpire or not.
