The judge does, fining the players their World Series shares ($3,362.26), and suspending them until May 20 of the following season. Judge Landis also outlaws gentleman's agreements and cover-ups of players optioned to the minors without proper paperwork. He declares six players free agents, including Heinie Manush, who will ride a 17-year career .330 batting average into the Hall of Fame in 1964.
