Playing Rules

  1. The entire roster of players present for the game shall bat in rotation with unlimited field substitution

  2. During the regular season, every effort should be made to play a game, regardless of attendance numbers.  A team may play with 8 players.  A team may share an outfielder.  Or two teams may shuffle players and scrimmage if necessary.  The goal is development of the kids. 

    • During the playoffs, a team must have at least 8 players to play a game.  Fewer than 8 players at any point in a game results in a forfeit

  3. Players may not sit out consecutive innings and may not sit out more than 2 innings per game. 

  4. If a player arrives after the start of the game, the player will bat last in the line up.  There is no penalty for the team.

  5. If a player leaves a game early, there is no penalty during the regular season.  Please alert the opposing team scorekeeper.

    • During the playoffs, if a player leaves early for any reason other than for injury, an out will be recorded the first time the player’s spot in the batting order comes up.  No further out will be recorded for subsequent times the leaving player’s spot comes up in the batting order.
  6. Runners may lead-off and steal bases, as in Official Baseball Rules.

  7. Age-appropriate balks will be called.  During the first three weeks of the season the pitcher will be warned before a balk is called.  There will be one warning, for each pitcher, and then a balk will be called.  After the first three weeks of the season no warning will be given prior to calling a balk. 

  8. During the regular season, there are no standings.  Playoffs will consist of round robin play and single elimination bracket following round robin play.  Round robin play will be determined by random draw.

Pitching Rules

  1. Pitchers shall not pitch more than two innings or 75 pitches, whichever is less, in a single game during the regular season.  If there are multiple games in a calendar week, pitchers shall not pitch more than 3 innings or 75 pitches in a calendar week, during the regular season.  (Monday to Sunday). 

  2. During playoffs, pitching limitations will be governed by Pitch Smart.  See below chart.

  3. Note:  The pitcher will only be required to observe the calendar day(s) of rest for the threshold the pitcher reach during the start of that at-bat, provided that pitcher is removed before delivering a pitch to the next batter. 

  4. As soon as a pitcher delivers one pitch to a batter, the pitcher shall be considered to as having pitched in one inning.

  5. Any pitcher withdrawn from the mound shall not be permitted to pitch again in the same game.

Length Of Games

  1. No new inning will be started after the 1-hour 45 minute time limit has expired.  The game will end (drop dead) at the 2 hour mark.  At that time, if an inning is incomplete, the incomplete inning will not count and any runs counted during that inning will be voided.

  2. Maximum of five runs per inning except in the sixth or last declared inning by the umpire which is open.

SBP Unique Rules

  1. How to deal with problems:

    • Parents sign a Code of Conduct form.  If their behavior is inappropriate, ask them politely to stop. If they still don’t cooperate, call the park enforcement officer and walk away.  Notify the league so the league can deal with the parent directly.

    • Any person(s) that interfere with you and/or your team during a game or practice (including unauthorized use of fields) should be dealt with in the same way.

    • Park Enforcement Officer – (310)345-1141

    • If P.E. Officer is unavailable, contact the Police Dept. Front Desk (310) 802-5140

  2. We are a ‘Hustle League’ and expect players to run on and off the field.

    • At the discretion of the umpire, a team that does not hurry can be assessed balls or strikes as a penalty for delay of game (Two minutes from the last out of the previous inning).

    • You can designate a substitute runner for a catcher, if the catcher is on base with two outs, so that they can get ready for the next inning. The substitute runner is the last recorded out for the hitting team.

  3. Calling Up Players
  • If a team expects to be short players, they may “call up” a substitute player from the division below. 
  • Mustang National teams will call up from Mustang American and Mustang American teams will call up from Pinto National. 
  • Pinto players cannot pitch in Mustang games.  Call-ups should bat at the bottom of the lineup.  Otherwise, Call-ups should be treated as any other member of the team.
  • Players may not substitute in for other teams in their own division.  Players may not participate as a substitute two levels above their registered level.  Children not registered with South Bay PONY may not participate as substitutes.

  1. Miscellaneous 

    • Both teams are responsible for set-up and break-down of the fields before and after a game.  This includes cleaning the dugouts after the game.

    • Each team is responsible for one new baseball for each game.

    • Fans are not allowed to sit directly behind home plate and the batter’s box.  The layout at each field is slightly different, so there is some discretion as to how this is interpreted at larger fields. 

    • Any manager that is ejected from a game will receive an automatic 1 game suspension and review for any further disciplinary action.
