This 1966 Tod Lansing creation bears no relation to the more widely known Championship Baseball marketed by Milton Bradley. It featuring two sets of 25 "chips" (thin counters) each of which represents a player on a 25 man roster for each team, plus offense and defense strategy cards. A cross-index of offense and defense cards determines play selection, and die rolls determine the exact results for each situation. Several different levels of play are offered. Both teams sets of player "chips" are identical; i.e., each player has the same 25 players to build their respective lineups from.
