Graded — this page is the complete record.

The lean (0 units — logged, not staked)

Pittsburgh Pirates -1.5 run line · confidence 44.5% of 10,000 sims · edge -3.5 pts · 0u

Randy Dobnak (2.73 ERA, 1.27 WHIP) vs Paul Skenes (3.78 ERA, 1.13 WHIP).

Projected 3.7–4.7; sim total 8.3 against a 8.5 line; park factor 0.97.

Market at board time: moneyline +160 / -190 (consensus at board time) · total 8.5.

Circuit-breaker log (7 checks)
  • Rule 2 fired: market line -182 exceeds the night-game juice cap (-180): pivoted off the moneyline to PIT -1.5 (covers 44.5% of sims).
  • Rule 8 check passed: raw model 59.1% vs de-vigged market 63.0%: 3.9-point divergence within the 12-point cap (blended to 44.5% at MODEL_WEIGHT=0.5).
  • Edge gate: model edge vs offered price is -3.5 pts (minimum 2). No allocation; a good side at a bad price is a bad bet.
  • Rule 4 check passed: both starters carry full-season workloads.
  • Rule 6 flag: away 14-day wOBA 0.280 trails league 0.321 by 0.041 (threshold 0.035). 8% run tax applied to the away run rate.
  • Rules 3/5 (velocity/spin telemetry): manual review required: Statcast feed not wired.
  • Weather (totals paper track ONLY): 75°F at first pitch: run environment x1.020. Applied to the paper totals pick; the staked board ignores weather entirely.

👁 Watch (market-proving, 0u): Under 8.5 (-105, Bovada) · model 55.4% · edge +4.1 pts · divergence +5.3 pts

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 (-105, Bovada) — 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.
