Season tracker

This page scores one outing. A season is not one outing.

A calculator cannot see that a pitcher also threw the last two days, or that he is coming back before his rest is done. This tracker follows the whole roster and flags it automatically: over the daily max, back too soon, and the third straight day Pitch Smart does not allow at any pitch count.

  • Availability board — set a date, see who can pitch, who is resting, who is barred
  • Auto-flags the three-consecutive-days rule this calculator structurally cannot catch
  • Pitch Smart limits built in, plus a printable dugout rules card
  • Excel + Google Sheets workbook, plus printable log and rules card

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.

Can a pitcher throw three days in a row?

No. Pitch Smart bars any pitcher from appearing on the mound three consecutive days regardless of pitch counts, even if every outing was short enough to require zero rest days. A pitcher who threw on Friday and Saturday is not eligible on Sunday, however few pitches were thrown. This calculator scores a single outing, so it cannot see previous days — track appearances across the week to apply this rule.

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.
