3rd Column Explanations: Positions: All pitchers marked by P. Position players who played half their games at one position are listed at that position. Those who played less than half their games at any position are listed at their two most-played positions. In the latter case, if both positions were in the outfield, the player is listed as "OF." Year: Year listed is first and last in the 1951-1975 time frame, not first and last in their career. For example, a player who played from 1949-64 would show "51-64" and a player who played from 1960-1979 would show "60-75." This also means that the position(s) shown are based on that time frame, rather than the player's entire career, as well.
