All Little League teams are required to comply with Little League pitching guidelines, which can be found here:
https://www.littleleague.org/playing-rules/pitch-count/. Little League sets a maximum number of pitches per day as well as a required rest (off days) in between outings based on number of pitches thrown.
Maximum Number of Pitches/DayDuring the regular season, DCLL has adopted the policy of decreasing each maximum pitches/day limit by 10, meaning that:
League age 6-8: 40 (instead of 50)
League age 9-10: 65 (instead of 75)
League age 11-12: 75 (instead of 85)
League age 13-16: 85 (instead of 95)
With limited early season practices and not knowing the condition of each player's arm coming into a season, the purpose of this change is to prevent arm fatigue. The DCLL-imposed limits are eliminated for both internal playoffs and summer tournament play.
Days Rest:
In addition to a maximum pitches/day limit, LL also has a prescribed 'days rest' schedule for pitchers. The following applies to all players age 13 and under:
1-20 pitches: 0 days rest (pitcher may pitch the next day)
21-35 pitches: 1 day rest (a pitcher who pitches Monday would not be eligible until Wednesday)
36-50 pitches: 2 days rest (a pitcher who pitches Monday would not be eligible until Thursday)
51-65 pitches: 3 days rest (a pitcher who pitches Monday would not be eligible until Friday)
66+ pitches: 4 days rest (a pitcher who pitches Monday would not be eligible until Saturday)
Note that a pitcher may finish an at bat and still fall under the previous days' rest threshold. For example, a pitcher has thrown 34 pitches and starts a batter on pitch 35. Regardless of how many pitches are thrown in that at bat, the pitcher would fall under the "21-35" range and only need 1 calendar day of rest. If the pitcher starts an at bat on pitch 36, even if it's a one pitch at bat, they would then need 2 days of rest (falling in the 36-50 range).
Consecutive Days
A pitcher may not pitch on three consecutive calendar days, regardless of pitch count. This is normally only a concern come playoffs.
Catching Restrictions
Any player who has caught 4 or more innings in a game is not eligible to pitch. Any pitcher who has thrown 41 or more pitches in a game is not eligible to catch.
