Lou Proctor

From BR Bullpen

Lou Proctor was a phantom ballplayer who was once listed in the baseball encyclopedias by mistake. He was listed as being a pinch hitter in a 1912 game,

Proctor was supposedly a telegraph operator in Cleveland, OH who inserted his own name into a Boston Red Sox box score on May 13, 1912, walking once as a pinch hitter for the St. Louis Browns. However, research in the 1980s revealed that the plate appearance actually belonged to Pete Compton. Whether Proctor ever really existed (even as a prankish telegraph operator) is unknown.
