From The Sporting News, 8/18/64, page 41:
Manager Don Bacon of Clinton (Midwest), who has won three straight half-season titles, was suspended by Phil Piton, president of the National Association, for 15 days, effective July 28. The suspension followed an altercation between Bacon and umpire Lary Ellis at Fox Cities, July 2. During the row, Ellis almost had his coat torn off his back, while Bacon received a head cut. League President Walter Wagner sat Bacon down for one day. The suspension by Piton followed an appeal by the umpire, who did not think the punishment was sufficient.
Hmmm.
