Rhett Lowder (5.13 ERA, 1.47 WHIP) vs David Peterson (5.17 ERA, 1.50 WHIP).

Circuit-breaker log (7 checks)
  • Rule 2 fired: market line -180 exceeds the day-game juice cap (-170): pivoted off the moneyline to CHC -1.5 (covers 46.1% of sims).
  • Rule 8 check passed: raw model 57.9% vs de-vigged market 63.0%: 5.1-point divergence within the 12-point cap (blended to 46.1% at MODEL_WEIGHT=0.5).
  • Edge gate: model edge vs offered price is -3.8 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 check passed: away 14-day wOBA 0.293 vs league 0.316 (gap +0.023, threshold 0.035).
  • Rules 3/5 (velocity/spin telemetry): manual review required: Statcast feed not wired.
  • Weather (totals paper track ONLY): 79°F at first pitch: run environment x1.035. 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.
