From time-to-time brief Provincial Leagues or Challenge matches involving teams from Connacht, Munster and Leinster outside of Dublin; as well as Dublin (SL Weekend League and ISA Inter-County Tournament) have been organized. These Leagues, Tournaments or Friendly matches have been separate from the Leinster and Ulster Softball Leagues which have been running since 1990 (LSL) and 2008 (USL) and the brief attempt at a Munster Softball League (2010-11). There has also been Weekend Leagues in Dublin (Gemstorm Winter League) and the Female Slowpitch League (Dublin).
