Slow Pitch - Bylaws & Rules

Illinois By-Laws & Playing Rules

For more information regarding the USSSA Playing Rules and By-Laws refer to the web site under “Rules & Legal Information.”

Managers are required to read the following information prior to competing in the Illinois USSSA program: Membership of this association automatically constitutes the agreement hereunder; including team classification. The following are by-laws instituted by the state of Illinois for adoption to the USSSA Constitution and are in no way contradictory to the USSSA National Association.

Player Eligibility – A player is eligible to compete in the USSSA program as long as he abides by the USSSA Constitution, by-laws and playing rules when listed as a member of an eligible team.

  1. Players are classified on the team which they play for (Major, A, B, C, D & E).
  2. A player can only be listed on one roster for tournament participation.

Team Eligibility – No team will be allowed to compete in the USSSA program without paying the team membership fee. Slow Pitch membership expires on December 31st. Fast Pitch membership is from August 1 thru July 31. A team may not be composed of more than 20 players (coaches and managers must be included in the 20 in order to play).  A team may always participate in a higher class tournament than what their team is classified. Teams wishing to participate in out-of-state tournaments must contact their State Director prior to travel.

Formula for Classifying Teams

The USSSA team classification system is the key to equalizing and balancing team competition in tournament play.  The USSSA does not classify leagues.  The USSSA does classify individual teams in leagues for tournament play. The main criteria for classifying teams is the overall strength of the team, both offensively and defensively, regardless of whether the team has ANY home run hitters.  Example: Depending on the strength of the offense and defense, a team with NO home run hitters may be classified as Major, A, B, C, D or E. Note: A team/player will be classified even if they do not participate in the USSSA program.
