The umpire is also an integral part of any no-hitter. The task of the umpire in a baseball game is to make any decision "which involves judgment, such as, but not limited to, whether a batted ball is fair or foul, whether a pitch is a strike or a ball, or whether a runner is safe or out… [the umpire’s judgment on such matters] is final." Part of the duties of the umpire making calls at home plate includes defining the strike zone, which "is defined as that area over homeplate "(sic)" the upper limit of which is a horizontal line at the midpoint between the top of the shoulders and the top of the uniform pants, and the lower level is a line at the hollow beneath the kneecap." These calls define every baseball game and are therefore integral to the completion of any no-hitter. Sixteen different umpires presided over the White Sox’ twenty no-hitters. Notably Eric Cooper umpired both Buehrle’s no-hitters, and Doug Eddings, who umpired Carlos Rodón's no-hitter, was also the umpire of the White Sox' 2005 American League Championship Series game 2 win over Los Angeles involving the infamous dropped third strike call.
