Why track at all
The research keeps landing on the same conclusion: overuse and pitching while fatigued are the strongest modifiable risk factors for serious arm injury in young pitchers, and young pitchers who throw more than 100 innings in a year carry several times the injury risk.12 The trouble is that overuse accumulates quietly across a long season. No parent can hold all of it in their head, game after game, team after team. Tracking is simply how you make the invisible visible.
What to track
1. Pitches and innings
Log daily pitch counts, and roll them up into weekly and full-season totals, including bullpens and warmups. The arm does not distinguish a game pitch from a side-session pitch. Keep an eye on the season innings, with roughly 100 competitive innings a year as a ceiling.3
2. Rest days
Required rest scales with how much your pitcher threw that day, so track the days off between outings, and never let him pitch on three consecutive days.3 At a busy tournament, rest thresholds get crossed fast, which is exactly when a written log beats memory.
3. The velocity trend
Velocity is a useful window into fatigue. Within a single outing, a clear drop in velocity is a sign the arm is tiring and the day is done. Across weeks, a velocity that sags and does not recover with rest can signal accumulated overload. You are not chasing a high number here, you are watching for an unexplained decline.
4. Recent workload versus baseline
The most useful workload concept is comparing recent throwing to the longer-term average the arm is used to. Injuries tend to cluster when workload spikes, when a pitcher ramps up too far, too fast, relative to what he has been doing. The goal is gradual change, not a sudden jump from a quiet stretch into a heavy weekend.
The single clearest red flag is a spike: a sudden jump in throwing volume after a lighter stretch. The second is a velocity or command decline that does not bounce back with rest. Either one is a reason to pull back, not push through.
Make it a system, not a guess
The point of tracking is not anxiety, it is decisions. When the numbers are in front of you, the calls get easier: rest him this weekend, skip the second team, back off the bullpen. This is exactly what a workload log is built to do, and it is the core of how CritchPitch tracks throwing and flags spikes and drift over a season. You can start by [screening a pitch and building the profile](/try).
The parent who tracks is the one who catches the spike before it becomes an injury. Everything else in arm health, pitch counts, fatigue, rest, runs on information you only have if you write it down.
Education, not a medical diagnosis or treatment plan. If your pitcher has pain, consult a qualified sports-medicine professional.
