Game Rules

We play Wiffle ® Ball at Yellowbatz. There are differences from baseball - that's why we don't call it baseball with plastic bats and balls. Our rules are defined and enforced for league play. It is at the organizer's discretion to apply the rules to games played at parties and special events.

  • One-and-Done is when the ball hits the strikezone and the batter doesn't swing,
    the batter is declared Out (This is so batters come to the plate with an intention to swing the bat)

  • Any ball that comes to a complete stop before the outfield is an Out
  • Foul Balls
  • There can be an unlimited number of foul balls per batter
  • Foul balls can not be caught for an out (we do not want players injured running off the field of play)
  • A Dead Ball will be called when a batted ball hits a ball laying in the field of play before the baseline
  • The ball will not count and play will continue before the dead ball happened
  • Double Plays
