Seth Lugo (4.61 ERA, 1.38 WHIP) vs Parker Messick (2.50 ERA, 1.01 WHIP).

Circuit-breaker log (7 checks)
  • Rule 2 fired: market line -178 exceeds the day-game juice cap (-170): pivoted off the moneyline to CLE -1.5 (covers 40.5% of sims).
  • Rule 8 check passed: raw model 54.2% vs de-vigged market 62.8%: 8.6-point divergence within the 12-point cap (blended to 40.5% at MODEL_WEIGHT=0.5).
  • Edge gate: model edge vs offered price is -5.5 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 check passed: away 14-day wOBA 0.374 vs league 0.314 (gap -0.059, threshold 0.035).
  • Rules 3/5 (velocity/spin telemetry): manual review required: Statcast feed not wired.
  • Weather (totals paper track ONLY): 78°F at first pitch: run environment x1.030. 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.
