Graded — this page is the complete record.

Chicago Cubs -1.5 run line · confidence 45.0% of 10,000 sims · edge -5.7 pts · 0u

Janson Junk (4.50 ERA, 1.34 WHIP) vs Shota Imanaga (3.80 ERA, 1.10 WHIP).

Projected 4.4–5.3; sim total 9.8 against a 6.5 line; park factor 1.02.

Market at board time: moneyline +169 / -200 (consensus at board time) · total 6.5.

Circuit-breaker log (7 checks)
  • Rule 2 fired: market line -195 exceeds the night-game juice cap (-180): pivoted off the moneyline to CHC -1.5 (covers 45.0% of sims).
  • Rule 8 check passed: raw model 56.6% vs de-vigged market 64.2%: 7.6-point divergence within the 12-point cap (blended to 45.0% at MODEL_WEIGHT=0.5).
  • Edge gate: model edge vs offered price is -5.7 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 0.332 vs league 0.322 (gap -0.010, threshold 0.035).
  • Rules 3/5 (velocity/spin telemetry): manual review required: Statcast feed not wired.
  • Weather (totals paper track ONLY): 59°F at first pitch: run environment x0.956. 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.
