4.1 The Association will follow the rules as established by the SSUSA or as modified by these JSSA Uniform Rules.

4.2  Uniforms, Equipment and Playing Rules Modifications:

       A. Team shirts and caps will be provided by the Association to all new registered players without additional charge. Team shirts are mandatory for league games and caps are optional.

       B. Balls must conform to the current regulations but must have a core no greater than 44 and a compression no greater than 375.

       C. Bats must conform to SS USA rules and have a bat performance rating (BPR) no greater than 1.21.

       D. The use of pitchers’ safety screens is mandatory for games and batting practices.

       E. The pitcher’s safety screen must be placed so that the edge of the screen’s box is in the middle of the rubber and is no more than three feet in front of the rubber. (Can be located on pitcher's glove hand OR throwing hand side.)

       F. A thrown ball that hits the pitching screen is in play.

        G. A regulation game will be nine innings unless halted by weather or managers’ agreement.

        H. The batter will start with a one ball and one strike count.     

        I. A base runner may stand in foul territory at first or third base. The base runner must announce his intention to the umpire and opposing team and retouch the base before advancing.

       J. All team players present must be included in a continuous batting order. Failure to do so will constitute an out.

       K. Any player present who does not complete the game will be recorded as an out for any remaining turns at bat. If a player is injured or has to leave the game for a personal emergency (family or business), he will not be recorded as an out and may be replaced subject to the agreement of both managers.

       L. Once a manager has confirmed a substitute for a roster player in a League game, the substitute must be permitted to play even if the roster player changes his mind. The roster player is eligible to play only if he is needed to avoid a forfeit. Additionally, game rosters may not change to accommodate late arriving players once the first pitch of the game has been thrown.

      M. Teams are limited to five runs per inning. The final inning will not have a run limit.

       P. Batter’s box:  The inside lines on both sides of the home plate are 6 inches from the plate. Each batter’s box shall be 3 feet wide and 7 feet long with 4 feet in front of a line drawn through the center of home plate. Although there may not be visible lines, in the judgment of the umpire if a batter steps out of the batter’s box after a pitch is thrown but before striking the ball, he will be called out. 

            Q.  A pitch thrown within correct altitude regulations shall be called a strike if it strikes any part of the wooden home plate structure. A ball landing near the board's edge will be called a ball or strike solely at the umpire's discretion.


R. Base runners may leave their base once a pitched ball passes the vertical plane of the plate. A runner leaving early will be called out at the discretion of the umpire and the play will be called dead per SSUSA Rules (Section 9, 9.1 G.)
