Graded — this page is the complete record.

The lean (0 units — logged, not staked)

Pittsburgh Pirates ML (-152, BetRivers) · confidence 56.9% of 10,000 sims · edge -3.4 pts · 0u

Jackson Jobe (6.23 ERA, 1.38 WHIP) vs Paul Skenes (3.88 ERA, 1.12 WHIP).

Projected 4.2–4.8; sim total 9 against a 8.5 line; park factor 0.97.

Market at board time: moneyline +137 / -153 (consensus at board time) · total 8.5.

Circuit-breaker log (7 checks)
  • Rule 2 check passed: market line -152 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 55.0% vs de-vigged market 58.9%: 3.9-point divergence within the 12-point cap (blended to 56.9% at MODEL_WEIGHT=0.5).
  • Edge gate: model edge vs offered price is -3.4 pts (minimum 2). No allocation; a good side at a bad price is a bad bet.
  • Rule 4 flag: Jackson Jobe under 60 IP this deep in the season (limited workload / possible IL return). Volume freeze: confidence downgraded one tier.
  • Rule 6 check passed: away 14-day wOBA 0.309 vs league 0.315 (gap +0.006, threshold 0.035).
  • Rules 3/5 (velocity/spin telemetry): manual review required: Statcast feed not wired.
  • Weather (totals paper track ONLY): 78°F at first pitch: run environment x1.031. Applied to the paper totals pick; the staked board ignores weather entirely.

Capture caveat, verbatim: first capture was after first pitch — weak close.

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.
