In-Game Rules
- Lineups of 9 players per team.
- No metal cleats allowed.
- An intentional bunt or half-swing will be called a foul (strike). Unintended mis-hits or check-swings are live.
- The infield fly rule is NOT effect. All pop-ups are live, whether caught or dropped, no matter the game situation.
- If someone is hurt or has to miss a game, both teams must agree to an equivalent sub. In case of injury mid-game, a team may play short a player. The opposition will provide a catcher, who is not responsible for making any fielding plays beyond returning each pitched ball to the pitcher.
- If the ball hits the fence on the right side of the field (1st base side), OR if it leaves the field of play completely, the ball is dead and each runner is entitled to the base he was running to plus one additional base. If the ball hits the fence on the left side of the field (3rd base side), the ball is live.
- On any ball out of play (home run or foul), no matter how quickly the ball is retrieved, the ump shall put the "backup ball" into play, with the retrived ball becomming the new "backup ball" to be rotated back into play the next time a ball goes out of play.
Scheduling/Tournament Rules
- Round-Robin Play: Each team plays four games, determining playoff seeding.
- Round-Robin Play: Coin flip determines home/away teams.
- Round-robin Play: Seven inning games (plus extra innings if necessary).
- Postseason Play: Nine inning games (plus extra innings if necessary).
- Postseason Play: Semifinals: #1 vs. #4, #2 vs. #3 (#5 and #6 eliminated).
- Postseason Play: Higher seed gets home field
- Seeding Tiebreakers (two teams): Head-to-head record.
- Seeding Tiebreakers (3+ teams): First, head-to-head record (winning percentage) among the teams in the tie. For example, if 3 teams are tied, but Team A is 2-0 against the other two, Team B is 1-1, and Team C is 0-2, their seeding is A-B-C. If head-to-head winning percentage is a tie, then the next tiebreaker is overall Run Differential. If looking at Run Differential reduces the tie to just two teams, that tie-within-the-tie is broken by head-to-head record. If the 3+ teams are still tied in Run Differential, the next tie breaker is overall Runs Scored, followed by a Coin Flip.
