What the walks allowed board is

The Walks Allowed board projects how many free passes a starter issues. One statistical model scores every matchup on the slate the same way — a star and a backup judged on the matchup in front of them, not their name — and every number is graded against the real box score once the games go final.

How the model gets its number

It isn't a gut call or a name game. The projection is built from a few things:

  • His control.
  • The lineup's patience.
  • Count leverage.

Those pieces combine into one number, and the model re-tunes itself weekly against how its past calls actually landed.

Is there a betting edge here?

Walks are near-unpredictable at the margin and the market prices them efficiently. Transparency board.

How to use it

A read on a starter's command for the night; no edge to bet.

Everything here is a research signal from the model, graded in public — not betting advice, and no outcome is guaranteed.
