Graded — this page is the complete record.

The lean (0 units — logged, not staked)

Houston Astros ML (-118, BetRivers) · confidence 53.3% of 10,000 sims · edge -0.8 pts · 0u

Emerson Hancock (3.35 ERA, 1.12 WHIP) vs Hayden Wesneski (3.86 ERA, 1.18 WHIP).

Projected 3.9–4.3; sim total 8.2 against a 8.5 line; park factor 0.97.

Market at board time: moneyline +109 / -120 (consensus at board time) · total 8.5.

Circuit-breaker log (7 checks)
  • Rule 2 check passed: market line -118 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 53.3% vs de-vigged market 53.3%: 0.1-point divergence within the 12-point cap (blended to 53.3% at MODEL_WEIGHT=0.5).
  • Edge gate: model edge vs offered price is -0.8 pts (minimum 2). No allocation; a good side at a bad price is a bad bet.
  • Rule 4 flag: Hayden Wesneski 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 0.291 vs league 0.315 (gap +0.024, threshold 0.035).
  • Rules 3/5 (velocity/spin telemetry): manual review required: Statcast feed not wired.
  • Weather: roofed park, no adjustment (totals paper track).

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.

❌ Watch pick (market-proving, paper, 0u staked): Under 8.5 (-102, LowVig.ag) — LOSS (-1.00u paper).

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