Honkbal Overgangsklasse

The Honkbal Overgangsklasse (Dutch for Baseball Transition League) is the second highest level of professional baseball in the Netherlands. It is a twelve-team league that plays a 22-game schedule followed by two separate 15-game schedules for the best six teams and the weakest six teams, and is overseen by the KNBSB. Games are played principally on weekends. The season runs from April to August and is followed by a promotion and relegation system with the highest level of baseball in the Netherlands, the Honkbal Hoofdklasse, so that the composition of the top level may change from year to year.
