Graded — this page is the complete record.

The lean (0 units — logged, not staked)

Boston Red Sox ML (-120, FanDuel) · confidence 52.8% of 10,000 sims · edge -1.7 pts · 0u

Sonny Gray (2.79 ERA, 1.15 WHIP) vs Jared Jones (5.03 ERA, 1.20 WHIP).

Projected 4.4–4.2; sim total 8.6 against a 7.5 line; park factor 0.97.

Market at board time: moneyline -123 / +110 (consensus at board time) · total 7.5.

Circuit-breaker log (7 checks)
  • Rule 2 check passed: market line -120 within the night-game juice cap (-180; night -180, day -170, day = first pitch before 17:00 venue-local).
  • Rule 8 check passed: raw model 52.0% vs de-vigged market 53.7%: 1.7-point divergence within the 12-point cap (blended to 52.8% at MODEL_WEIGHT=0.5).
  • Edge gate: model edge vs offered price is -1.7 pts (minimum 2). No allocation; a good side at a bad price is a bad bet.
  • Rule 4 flag: Jared Jones 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 0.350 vs league 0.315 (gap -0.036, threshold 0.035).
  • Rules 3/5 (velocity/spin telemetry): manual review required: Statcast feed not wired.
  • Weather (totals paper track ONLY): 80°F at first pitch: run environment x1.038. Applied to the paper totals pick; the staked board ignores weather entirely.

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.
