Athletics outfielder Lawrence Butler voiced his displeasure with the umpires in MLB, expressing that he feels there's a lack of accountability among big league umpires that doesn't exist at the Triple-A level.
Butler said Monday that he's "fed up" with MLB's umpires and said that minor league umpires displayed more caution in regards to the strike zone due to the existence of the automated ball-strike system that's in place, a system which MLB tested use of during the All-Star Game.
