FAQ

Questions about pitch counts and rest days

How many pitches can a youth pitcher throw in a day?

Under MLB Pitch Smart guidelines the daily maximum depends on age: 50 pitches for ages 7–8, 75 for ages 9–10, 85 for ages 11–12, 95 for ages 13–16, 105 for ages 17–18, and 120 for ages 19–22. These are hard caps for a single calendar day, not targets.

How many rest days are required after pitching?

Required rest scales with pitches thrown. For ages 14 and under a common schedule is: 1–20 pitches no rest, 21–35 one day, 36–50 two days, 51–65 three days, and 66 or more four days. For ages 15–18 the thresholds widen (for example 1–30 no rest, up to 81+ requiring four days). The calculator applies the exact table for the age you select.

Does a rest day mean a full calendar day off?

Yes. One required rest day means the pitcher should not pitch the next calendar day and is eligible again the day after. The calculator shows the earliest eligible return date when you enter the date pitched.

What counts as a pitch for the count?

Every pitch thrown in a game counts toward the daily total and the rest requirement, including balls, strikes, and foul balls. Warm-up pitches between innings are not counted. Pitch Smart is based on game pitches thrown.

Are these limits a guarantee against injury?

No. Pitch counts and rest days reduce overuse risk but do not eliminate it. Mechanics, throwing year-round, playing on multiple teams, and pitching while fatigued all add risk. Treat the guidelines as a floor for arm care, not a ceiling on caution.
