The lean (0 units — logged, not staked)

Chicago White Sox ML (-125, LowVig.ag) · confidence 52.8% of 10,000 sims · edge -2.7 pts · 0u

Andrew Sears (5.40 ERA, 1.38 WHIP) vs David Sandlin (5.64 ERA, 1.19 WHIP).

Projected 4.6–4.8; sim total 9.4 against a 8.5 line; park factor 1.03.

Market at board time: moneyline +111 / -130 (consensus at board time) · total 8.5.

Circuit-breaker log (7 checks)
  • Rule 2 check passed: market line -125 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 51.3% vs de-vigged market 54.4%: 3.1-point divergence within the 12-point cap (blended to 52.8% at MODEL_WEIGHT=0.5).
  • Edge gate: model edge vs offered price is -2.7 pts (minimum 2). No allocation; a good side at a bad price is a bad bet.
  • Rule 4 flag: Andrew Sears, David Sandlin 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 0.334 vs league 0.321 (gap -0.013, threshold 0.035).
  • Rules 3/5 (velocity/spin telemetry): manual review required: Statcast feed not wired.
  • Weather (totals paper track ONLY): 69°F at first pitch: run environment x0.995. 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.
