Youth Pitch Counts and Arm Care

Youth · By 4Baseball Staff · September 20, 2026 · 6 min read

The published Pitch Smart and Little League pitch limits and required rest days, what they leave out, and why fatigue is the risk that matters most.

Every coach of a youth team eventually stands on a mound in the fifth inning with a tired eleven-year-old and a one-run lead. The published guidelines exist so that decision is not yours to improvise. Below are the limits as the governing bodies actually publish them, with nothing added and nothing rounded off.

This page is general information, not medical advice. It reproduces published guidance so you can find it in one place. It is not a diagnosis, a training plan or a substitute for a qualified medical professional. If a young player has arm pain, the answer is to stop throwing and get them seen. Do not pitch through it, and do not let a pitch count tell you an arm that hurts is fine.

What the limits are actually for

Pitch counts are not really about a single game. They are a proxy for fatigue, and fatigue is the thing the research keeps pointing at. Writing on Little League's site, orthopaedic surgeon Dr. James Andrews — a Little League International board member and co-founder of the American Sports Medicine Institute — describes research at ASMI and the Andrews Research and Education Institute showing that a young player who plays fatigued has a "36 to 1 increased incidence" of injuring the throwing shoulder or elbow. He splits fatigue into three kinds: too many pitches in a game, too many across a season, and playing year-round.

That is why the guidance below has three layers — a daily maximum, required rest between outings, and annual limits on innings and months. Skipping the third layer while obeying the first is the most common mistake in youth baseball.

Pitch Smart limits and required rest

Pitch Smart is the joint MLB and USA Baseball programme. These are its published recommendations. Each row is a daily maximum, then the pitch ranges that trigger each amount of rest.

Pitch Smart attaches the same set of recommendations to every age group: warm up properly, follow the counts and rest, avoid playing for more than one team at a time, avoid playing catcher when not pitching, and do not pitch in more than one game on the same day. Across all ages it states that no pitcher should appear as a pitcher on three consecutive days regardless of pitch counts. For ages twelve and under it says to avoid throwing anything other than fastballs and changeups; from thirteen it says players can begin using breaking pitches once they have a consistent fastball and changeup.

There are also yearly ceilings that nobody tracks and everybody should. Pitch Smart caps combined innings pitched in any twelve-month period at 60 for ages eight and under, 80 for ages 9-12, and 100 for ages 13-14 and 15-18. It asks for at least four months off from throwing each year for ages 14 and under, with two to three of those months continuous; for 15-18 it asks for four months off from competitive pitching including two to three continuous months off all overhead throwing.

Little League Regulation VI

If you coach in Little League, the regulation — not the recommendation — is what binds you. Little League groups by league age, which is not always the same as the age groups above.

Required rest for pitchers league age 14 and under: 1-20 pitches, no rest day; 21-35, one day; 36-50, two days; 51-65, three days; 66 or more, four days. For league age 15-16: 1-30, no rest day; 31-45, one day; 46-60, two days; 61-75, three days; 76 or more, four days. Little League adds that under no circumstance shall a player pitch on three consecutive days.

Two details catch coaches out. First, a pitcher who reaches the limit mid-batter may finish that batter — but may not start a new one. Second, the catching rules: a player who has caught four or more innings in a game may not pitch that day, and a player who caught three innings or fewer, moved to the mound and threw 21 or more pitches (31 for 15- and 16-year-olds) may not go back behind the plate that day.

Little League Softball counts innings, not pitches

This surprises people who move between the two sports. Little League Softball pitching eligibility is governed by innings. In the Minor and Major divisions a player may pitch a maximum of twelve innings in a day, and a player who pitches in seven or more innings in a day must take one calendar day of rest. A single pitch counts as having pitched in that inning. Junior and Senior League softball have no pitching restrictions, though a local board may add its own.

Where the published guidance does not line up

Be aware of the seams, because coaches who play in more than one programme hit them.

The age bands differ. Little League runs a single 13-16 band at 95 pitches; Pitch Smart splits 15-16 at 95 from 17-18 at 105. Little League's youngest band starts at 6, Pitch Smart's at 7.

The breaking-ball advice differs too. Pitch Smart says avoid anything but fastballs and changeups through age twelve. Dr. Andrews, writing on Little League's site, recommends waiting until a player has been through puberty. Little League itself published results of a five-year study with USA Baseball and the University of North Carolina that "failed to show an increased risk of arm injury due to breaking pitches" and found overuse to be the primary cause — which is why Little League has not banned the curveball. All three agree on the part that matters: workload, not pitch type, is the dominant risk.

One more oddity worth knowing if you coach older players. Pitch Smart's 19-22 row lists a daily maximum of 120, but its published rest table stops at 81-105 for four days' rest. When MLB and USA Baseball announced updates to the programme in 2017, they specified a minimum of five days' rest after 106 or more pitches for that age group. The current table does not show a five-day column, so check the source before relying on it.

Finally, and most importantly: these numbers change. Sanctioning bodies revise them, and your league may impose stricter limits of its own, which Little League explicitly permits its local boards to do. Treat this page as a map, and your league's current rulebook as the territory.

Signs to stop

Rest days are a floor, not a target. A pitcher who is short-arming, dropping their elbow, losing command late, rubbing a shoulder between innings or asking to stay in is telling you something a counter cannot. Pitch Smart lists monitoring for other signs of fatigue alongside every numerical limit, for exactly that reason.

Pain is different from tiredness. Pain in the elbow or shoulder of a young thrower is a reason to stop that day and see a qualified medical professional before the next outing — not a reason to count backwards from the limit and decide there are pitches left. Nothing on this page is medical advice.
