Divisions & Age Regulations

Divisions are based upon a player’s age as of the 2018 League Age date (April 30th, 2018). To determine a player’s League Age, use USSSA’s age calculator. Players may play up in age but may not play down. The 2018 season runs from Aug. 1, 2017 to July 31, 2018. The minimum age to play in a kid-pitch program is a League Age 6. Players younger than the League Age must have the approval of the state Director, John Gleason, to play kid-pitch. For approval contact John at Players playing up in age may not play up more than two (2) league ages. For example, a 12U player may play up to 14U but not to 15U.

Tournament Participants
Players are permitted to play on only one team during a weekend tournament. This rule applies no matter where the USSSA tournament is located in Southern California. Any team knowingly using an illegal player shall be subject to discipline including but not limited to: forfeiting a game, ejection from tournament and/or suspension from all USSSA sanctioned leagues and tournaments for a one year period.

Teams are required to have non-duplicating numbers on their jerseys at least 4 inches in size. Players may not change numbers during the tournament. The number they wear in the first game of the tournament shall be their number for the remainder of the tournament. The only exception is if a player must change jerseys due to blood on the original jersey. Should this occur, the change must be reported to the tournament director immediately. If a player plays with a different number during the tournament, both the player and team manager will be ejected from the game.

Metal cleats are prohibited for teams 12U and below.

Teams are prohibited from warming up or conducting their pre-game on any of the infields, no matter what the facility. Warm up is permitted in foul territory only!

Major League Baseball’s Sporting News Rules shall apply, along with those found in the USSSA Bylawsbooklet.

More information on the Frozen Roster rules can be found under section 3.07 on Page 2.


Right handed pitchers may not fake a pickoff attempt to third base. This is a balk. A pitcher who steps toward first or third must throw to that base. Pitchers are permitted to step toward second base without throwing to that base.

To intentionally walk a batter, a coach simply needs to inform the umpire and point to first base. No pitches are thrown.

Tournament Pitching Restrictions:
7U, 8U 9U, 10U, 11U, 12U: 6 innings in a day, 9 in the tournament
13U, 14U: 7 innings in a day, 11 in the tournament.
15U & up: no pitching restrictions

Pitching Distances for all USSSA baseball tournaments are as follows:
7U – 8U: 40 foot mound, 60 foot bases
9U: 46 foot mound, 65 foot bases
10U: 46 feet mound 65 foot bases,
11U – 12U: 50 foot mound 70 foot bases
13U: 54 foot mound 80 foot bases (Some 14Us will play 54×80)
14U & up – 60.6 foot. mound 90 foot bases
On a single weekend tournament, pitching does not recycle for the playoffs. Once a pitcher is removed from the mound, he may not pitch again in that game. Umpires show leniency on balks in 9U and below.

Violation of pitching restrictions will result in the automatic ejection of the offending Manager. All teams will receive a Pitching Log at check in for their own records. Official pitching logs will be available at after each round of games.

Base Running
Teams in the 7U and 8U divisions may not lead off or steal home. Home plate is dead. Runners from 3rd base may only advance on a hit ball or when forced-in by a walk. Runners may steal after the ball crosses home plate. Bunting is allowed. When a runner is stealing home from third is put out, the runner is out. If called safe the runner is returned to third base.
The ball is dead when the pitcher has the ball in area of mound. The infield fly rule is in effect.
Courtesy runners will be allowed for the pitcher or catcher at any time. The courtesy runner must be a player not currently in the game or if the team has no players on bench, the last out. A courtesy runner may only run one time per inning. It is the base runner’s responsibility to avoid contact with the fielder when he has the ball. Slide or avoid is in effect at all times when fielder is in possession of ball. Intentionally running into a fielder who is in possession of the ball is grounds for ejection.

Teams may elect to bat 9 players AND/OR bat 10 players with the 10th player being an EH. The EH is considered a defensive player and may switch in and out defensively. Teams may also bat their entire roster. If a team bats entire roster or has no subs when a starter is injured, an out is recorded each time the injured player’s spot comes up to bat. Once a player is removed from a game due to injury, he may not return. Starters may re-enter only one time only in their original spot on the line-up.

Only 11U divisions and up may use the DH, and EH to insert 11 batters in their line up. 
Teams may play with 8 players with an out being taken for each time the 9th spot comes up. A 9th player may be added any time during the game.

PLEASE NOTE: In Southern California Tournaments, 14U teams and older must use BBCOR or Wooden Bats.

Length of Game
07U – 08U: Play 6 innings with no new inning after 1 hour 30 minutes (5 runs per inning max., last inning open)
09U – 12U: Play 6 innings with no new inning after 1 hour 45 minutes
13U & up: Play 7 innings with no new inning after 2 hours

These time limits will be applied to all pool play and non-gold division championships games. We will make every attempt to put no time limit on Gold division championship games.
Once an inning begins, it must be completed. However, if the home team is ahead and batting when time expires, the game is over and the inning is not completed. In an effort to keep games on time and to conserve pitching, no extra innings are played during pool play. Games will end either at end of scheduled innings or when time expires. If time expires in a tie game during pool play, the game is called a tie.

In the event a team cannot make it’s scheduled time the tournament director will first attempt to condense the schedule. If the schedule cannot be condensed a forfeit win will be awarded.
A win awarded by forfeit will be scored as 1 run for each scheduled inning. (example, a 12u game scheduled for 6 innings will be scored 6-0 for the winning team). USSSA reserves the right to modify the length of games due to issues involving limited visibility or park curfew. Every effort will be made to finish the tournament but in cases of rain, darkness or other acts of God, the tournament director reserves the right to shorten games or modify schedules in order to finish the event.

Pool Play Standing will be sorted on the following
1. Winning PCT,  2. Head to Head (only used when two teams are tied, with three or more tied, the next tie breaker is used) 3. Runs Allowed  4. Runs Scored 5. Runs Scored

Rainout/Tournament Cancellation Policy

In the event of tournament being cancelled by weather or any other unpreventable occurrence, every effort will be made to complete the tournament. Schedules may be changed, games may be shortened and a two day tournament may become a one day tournament. In the event of a rainout with no make-up tournament scheduled, we will offer all teams a credit based on the following criteria:A full rainout, meaning no games were played, a credit will be issued for the entire entry fee
If one game was played, a team will receive credit for ½ of the entry fee
If two games are played, no credit will be given
All credits must be used in Southern California USSSA Tournaments
If a tournament is rained out while in progress and a make-up is scheduled, there will be no refund or credit for teams that do not play the make-up. The tournament director has the right to alter schedules, adjust time limits, or adjust the number of playoff participants in order to complete the tournament. The tournament director also has the right to alter the amount of the credits issued.

The Home team will be determined by a coin flip and occupy the 3rd base dugout. Winner of coin flip has option to choose visitors. In the playoffs, the higher seeded team will be the Home team for duration of tournament. Each team may provide a scorekeeper but all changes must go through the home plate umpire, who is the official scorekeeper.

All conversations with an umpire should be conducted after a time-out has been called and be handled in a calm and professional manner. Verbal abuse of the umpire will not be tolerated and may result in ejection from the game.

Any manager or coach ejected from the game is required to sit out the next game also. After being ejected, a manager or coach must vacate the premises of the current game and the next game in which he is suspended. Any manager caught continuing to coach after being ejected or suspended will be suspended for an additional period of time. Any player ejected from a game is subject to a one game suspension at the tournament director’s discretion.

Managers are responsible for the conduct of his players and fans at all times. Managers are subject to ejection if his players or fans are out of control.

No more than three (3) coaches will be allowed in the dugout during USSSA games. All assistant coaches must be listed on your team’s online roster on There is a drop down menu to add them. In addition, no one other than official team coaches and players are allowed in the dugout at any time.

To protest a game, the umpire must be informed that the game is being played under protest. Once the protest has been made, you must get a ruling from a tournament director immediately. Do not continue the game under any circumstances. Once the next pitch is thrown, both teams have lost the right to protest.

Any team forfeiting a game may not advance to playoff round if it is determined that it is beneficial to that team with regard to runs allowed/differential, etc.
