This is the naming conventions guideline for the naming of Wikipedia articles about baseball players, including managers, coaches, umpires and other personalities associated with the sport.
As sports go, baseball has a long, rich and well-documented history, resulting in the creation of several thousand biographical articles for baseball players. To avoid confusion among baseball biographies, and to avoid duplication of articles, a set of article naming standards has been proposed:
The title of an article for a baseball player should reflect the name they most commonly went by during their career. Informally, the name that appeared on a player's baseball cards should serve as the article's title.
Nicknames should only be used when a player went by their nickname professionally instead of their given first name.
Because of the large number of articles about baseball players, disambiguation is often necessary. In cases where two (or more) ballplayers share the same name, disambiguation is often complex and confusing.
