Jared Jones (4.76 ERA, 1.25 WHIP) vs Quinn Mathews (6.43 ERA, 1.79 WHIP).

Market at board time: moneyline -115 / +104 (consensus at board time) · total 7.5.

Circuit-breaker log (7 checks)
  • Rule 2 check passed: market line -112 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 49.2% vs de-vigged market 52.2%: 3.0-point divergence within the 12-point cap (blended to 50.7% at MODEL_WEIGHT=0.5).
  • Edge gate: model edge vs offered price is -2.2 pts (minimum 2). No allocation; a good side at a bad price is a bad bet.
  • Rule 4 flag: Quinn Mathews under 60 IP this deep in the season (limited workload / possible IL return). Volume freeze: confidence downgraded one tier.
  • Rule 6 flag: away 14-day wOBA 0.271 trails league 0.316 by 0.045 (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): 83°F at first pitch: run environment x1.053. 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.

❌ Watch pick (market-proving, paper, 0u staked): Over 7.5 (+105, BetRivers) — 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.
