* When data available
** Ultimate Replay Guides for pre-1947 seasons are based on box score data, not play-by-play data, and some data is derived from incomplete information. Information for opposing pitcher handedness is not currently available using box score data. Inning of substitutions is sometimes not available. Game scores at the substitution point is based on the score at the beginning of a half inning (if inning is known). Defensive replacement details shows the starter at the defensive position as the replaced player.

* Some data for 1948-1955 are also based on box score information.

If there's something else you'd want to see in these, let me know!

NOTE: All of my Player Appearance Grids with Transactions are based off of the OFFICIAL transactions as provided by the Office of the Commissioner to all MLB franchises via the "Office of the Commissioner Official Bulletins" and have been obtained from the Giamatti Research Center at the National Baseball Hall of Fame. These Player Appearance Grids with Transactions take many hours of proofing.
