What's your kid's number?

Answer what you saw from the stands this week. We'll estimate every throw the scorebook didn't count. Estimates, shown as a range, with the math visible. Nothing here is a diagnosis.

Compare this week to his usual week

What does a normal week look like for him, in season? Rough is fine. If every other week looked like this, we can tell you how much this week stood out.

The honest read

Pitch Smart daily max for ages 11 to 12: 85 pitches. No pitching logged this week, so the only official check doesn't apply. The throws still count.

Fill in a week to see it.

What this can't tell you: how hard he threw, how far, or how the arm felt. So, one question. Did he say anything about his arm this week? If yes, that's a conversation with his coach, not a number on a screen.
