An excerpt from Kevin T. Czerwinski :
Perhaps the most impressive aspect surrounding what Charles "Whammy" Douglas did during the 1954 Georgia-Florida League season is the fact that he doesn't really consider it all that impressive.
Pitching for the Brunswick Pirates, Douglas set the league record with 27 victories while leading his team to a first-place finish and a berth in the circuit's championship series. What that little line in the record book doesn't tell you is that he did so with only one eye.
Douglas, whose other claim to fame was his nickname, lost his right eye as an 11-year-old yet prospered as a pitcher, often dominating older players at higher levels until he signed a professional contract with the Pirates in 1953. Douglas eventually pitched in the Major Leagues, going 3-3 in 11 games for Pittsburgh in 1957. But in a cruel twist of fate, it was his elbow and his shoulder, not his eye, that kept him from having greater success on the mound.
There have been less than 10 one-eyed players in professional baseball history.
