Biography
Chet Trail was the only player ever who was on a postseason roster, but who never appeared in a regular season or postseason game. This strange occurrence happened when the New York Yankees put him on their 25-man roster for the 1964 World Series. He was their 25th player during the season under a special 1964 rule permitting one bonus player to play in the minors while being charged to the 25-man roster. Commissioner Ford Frick ruled that Trail was eligible for the World Series roster, but he was not formally activated, and the Yanks played with 24 players during the 1964 World Series, which they lost to the St. Louis Cardinals in 7 games. http://www.baseball-reference.com/bullpen/Chet_Trail
