Events List & Schedule
All Division B and Division C tournaments (Invitational, Regional, and State) in Washington state will follow the WSO Unified Schedule. Tournaments may add additional time blocks as needed to accommodate teams and their venue. A draft schedule for the season is typically posted in early October with opportunities for coaches to comment before it is finalized end of October.
