ROSTER RULES
Active Roster: The active roster currently has 18 players. It will expand to 24 in the playoffs.
Player Eligibility: For the Collegiate League, any collegiate player, incoming freshman (Class 2025), or graduating high school senior (Class 2026). For the High School League, any High School Player in Class 2027, 2028, and 2029.
GAME LENGTH RULES
Regular Season: All games will be seven (7) innings long, with a time limit of two hours thirty minutes (2:30).
Post-Season: All games will be nine (9) innings, with a time limit of two-hour forty-five (2:45) minutes, unless both teams play one another in a doubleheader. Those games would be two (2) seven (7) inning games.
No new inning will begin after the time limit has been reached; however, any already underway will be played to completion except for games that need to be stopped due to rain, lightning, inclement weather, or darkness. In this case, the score will revert to the last completed inning.
All time limits are from the actual game time start, not the scheduled game time.
INTERNATIONAL TIEBREAKER RULE
If the game is tied after nine (9) complete innings, the league will utilize the “International Tiebreaker Rule.” The tiebreak will be used in the 10th inning, and innings will start with runners on first and second with no out.
MERCY RULE
The game is over when a team is ten or more runs ahead after five innings for a 7-inning game in the regular season. The mercy rule will not apply to the playoffs.
COURTESY RUNNERS RULE
This rule intends to speed up the game and allows the team at bat to use courtesy runners for the pitcher and/or the catcher at any time.
DESIGNATED HITTER (DH) RULE
The designated hitter rule allows teams to use another player to bat instead of the pitcher. Because the pitcher is still part of the team’s nine defensive players, the designated hitter -- or “DH” -- does not take the field on defense.
- Designated Hitter (DH) will be allowed during the season (not mandatory).
EXTRA HITTER (EH) RULE
This rule intends to provide maximum exposure, instruction, and developmental opportunity while enhancing the offense in the game.
**The Extra Hitter (EH) will be mandatory during the regular season. Teams shall not bat less than ten (10) players if a position player is available on the bench unless a team has only nine (9) position players available.** (The EH rule is not mandatory during the playoffs).
PRIBL Baseball Extra Hitter (EH) rule stipulates the following:
- The EH must be declared on the starting line-up before becoming official at the home plate meeting.
- The EH may bat in any spot in the batting order. However, the EH spot in the batting order may not change during the game.
- The EH is eligible for substitution.
- The EH may be entered into the game defensively. This means a manager can make defensive moves that include the EH, including swapping a defensive player for the EH. After that, the defensive player that was just swapped out can become the new EH. These are defensive swaps, not substitutions.
- The EH role may not be eliminated during the game, and once you start with an EH, you must keep the EH for the entire game. The only exception is if your team drops to only nine players due to injury, ejections, or players leaving early.
PITCHERS USE LIMITATION RULES
The PRIBL Summer Baseball Leagues will implement guidelines on pitch counts and rest periods across the season.
- Players should not pitch in multiple games on the same day.
- No pitcher shall appear in a game as a pitcher for three consecutive days, regardless of pitch counts.
Daily Max (Pitches in Game) | 0 Days Rest | 1 Day Rest | 2 Days Rest | 3 Days Rest | 4 Days Rest |
95 | 1-30 | 31-45 | 46-60 | 61-75 | 76+ |
