If the base is occupied and there are less than 2 outs, the hitter is automatically called out.

General

  • The score will be recorded and the team with the most runs wins.
  • The umpire will be in charge at all times and their decision will be final.
  • If the rules are not listed above, Wellington Softball Association rules apply (as per the by-laws/rule book). If the rule is not listed there, then Softball NZ rules apply.
