Scorekeeper Billy talks to Joey about seeing former players in the field in his imagination and mentions Cap Anson, Three-Finger Brown, Joe Tinker, Johnny Evers, and Frank Chance. Taking into account that in this version of the play, the Cubs are called the Bruins, so things might have been different, none of the named players played with the Cubs in Wrigley with the exception of Tinker, but not as part of the Tinker-to-Evers-to Chance combination Billy mentions.
