  • The home team will be determined at the beginning of the game by a bat toss.
  • The ball must be pitched underhand, and must arch at least six feet but no more than 12 feet in height from the ground.
    • This must happen or a “no pitch” will be called. Co-ed - a “no pitch” WILL count as 1 of the 3 pitches.
  • Bunting is not allowed.
    • Bunting is defined as any attempt by the batter to avoid swinging the bat all the way through.
  • Each team must provide a catcher.
    • The catcher MAY NOT block the plate.
  • The runner may only advance one extra base on an overthrow.
    • If the runner is already making an attempt at advancement at the time of the over throw, they will get that base plus one.
  • The runner may not leave the base until the batter has made contact with the ball.
    • Therefore, no leading off or stealing a base is allowed.
  • Teams must establish a batting order prior to the game and follow the order throughout.
    • A player not in the original batting order may sub in (and take someone else's spot in the line up).
    • Batting out of order will result in an OUT.
  • Foul balls will be called along each baseline at the umpires discretion.
  • On a close play, the runner must slide.
  • Infield fly rule is in affect. 
    • The infield fly rule is a rule that treats certain fly balls as though caught, before the ball is caught and even if the infielder fails to catch it or drops it on purpose.
    • An Infield Fly is a fair fly ball (not a line drive) that, in the judgment of the umpire, can be caught by an infielder, pitcher, or catcher with ordinary effort and when there are runners on first and second or first, second, and third and less than two outs.
    • The umpire's declaration of an infield fly means that the batter is out (and all force plays are removed) regardless of whether the ball is caught.
  • Before the mercy rule comes into effect, there is a 10 run limit per team per inning. 
  • Each team is allotted 3 "out-of-the-park" homeruns per inning, all additional homeruns will be considered a foul ball.
    • In the park homruns do not count for this rule.
    • On Tutt Science, a homerun is constituted as a fly ball (not a line drive or ground ball) that clears the path surrounding the outfield.
    • On Armstrong West, a fly ball clearing the path in right field will be considered a homerun. However, due to the short left field, a homerun hit to left field will be called at the umpires discretion.
    • On Armstrong Quad, any fly ball easily clearing the path surrounding the outfield will be counted as a homerun.
  •  If a pinch runner is needed, the last batted out will be allowed to run the bases in place of the batter. 
    • A pinch runner will be allowed to take the batters place one the batter is called safe.
    • In the case that there is no last batted out, the individual furthest from the batter in the batting order will be allowed to run.
  • The play is considered dead, and no runners may advance once the ball is given to the pitcher.
    • The batting team's pitcher must not interfer with the fielding team's attempt to end the play. 


  • Roster changes are permitted throughout the regular season, however, any names added to your roster may not be listed on another roster. Your roster will be considered “frozen” as soon as the post-season tournament starts.
