Ed Irwin
Ed Irwin played third base for the Tigers on May 18, 1912 as part of a squad of replacement players. Many readers here know the story of Ty Cobb being suspended by American League president Ban Johnson for attacking a heckler in the crowd, and the team's subsequent refusal to take the field until Cobb was reinstated. After Johnson threated to fine Tigers owner Frank Navin $5000 for any forfeited games, the notoriously tight fisted Navin ordered Tigers manager Hughie Jennings to "find players". The Tigers were in Philadelphia to play against the Athletics, and sources report that Jennings recruited any young men he could find in the neighborhood of Shibe Park, the Athletics' home. Irwin was one of those young men, and in his only major league game, he astonishingly hit two triples in three at bats. Tigers starting pitcher Allen Travers, also making his only MLB appearance, said that he was actually pitching well "until they started bunting. The fellow playing third base had never played baseball before." According to Wikipedia, Irwin died four years later when he was "thrown through a saloon window in Philadelphia, a shard of glass penetrating his jugular vein." There is no report on whether the squad of replacement players was issued Tigers uniforms, or if they just played in whatever attire they happened to be wearing when found. Also, this is what the internet offers for an image of Ed Irwin.
