  • Rule 2 check passed: market line -140 within the day-game juice cap (-170; night -180, day -170, day = first pitch before 17:00 venue-local).
  • Rule 8 check passed: raw model 53.2% vs de-vigged market 57.0%: 3.9-point divergence within the 12-point cap (blended to 55.1% at MODEL_WEIGHT=0.5).

  • Rules 3/5 (velocity/spin telemetry): manual review required: Statcast feed not wired.

The close is the last pre-first-pitch capture. Movement toward a side after we post is the fastest honest read on pick quality — see the CLV column on the ledger.

No stake rode on this game. The lean and its failed gates above are the whole position: passing is a position too.
