Affectionately called “Pops” by those who knew him, DiMuro was struck by a car and killed in Arlington, Texas, shortly after umpiring a twi-nite White Sox-Rangers game. He was beset by accidents throughout his career. In May 1979 the Yankees Cliff Johnson crashed into him in a play at the plate and sidelined him for most of the season. Two years later he suffered a sprained back and severe bruises when he slipped and fell in the Milwaukee visitors’ dugout during a rain delay. Ironically, his umpiring career began due to an injury; he had broken a finger while playing baseball in the Air Force and turned to umpiring to remain active.
