Koufax teams enter into Byron Park District league. Al Morrison fields teams for this league, but does NOT run this league. This league follows IHSA High School Rules since it is generally 8th graders and incoming freshman. Emphasis changes more to winning and higher skill development needed to advance to high school baseball. The rules dictate the teams must field and bat 9, but allows all players to bat in the regular season. There is not an innings played on defense requirement, although we recommend to our coaches that all players should be given opportunities to play in the field. We also emphasize to the coaches to make sure players have the defensive skills to be able to protect themselves in infield positions as they are now facing batters that can hit the ball much harder. There is a regular season champion and tournament champion.
