On July 14, 1950 The Waterbury Timers of the Colonial League have a franchise but no players when the 12-man squad is fired after refusing to board the team bus for two scheduled games at Kingston, NY. Strike issues are several: the players claim that the team bus is unsafe; the bus is scheduled to bring them home after the first game and return for the second rather than lay over; six players claim that the club reneged on the promise of a pay raise if they were still on the roster on June 2. The league will disband on July 16.
