Athletics @ Boston Red Sox

Graded — this page is the complete record.

The lean (0 units — logged, not staked)

Boston Red Sox -1.5 run line · confidence 47.2% of 10,000 sims · edge -5.2 pts · 0u

J.T. Ginn (3.51 ERA, 1.21 WHIP) vs Erik Miller (2.57 ERA, 1.34 WHIP).

Projected 3.8–5.1; sim total 8.9 against a 9.5 line; park factor 1.06.

Market at board time: moneyline +203 / -235 (consensus at board time) · total 9.5.

Circuit-breaker log (7 checks)
  • Rule 2 fired: market line -227 exceeds the day-game juice cap (-170): pivoted off the moneyline to BOS -1.5 (covers 47.2% of sims).
  • Rule 8 check passed: raw model 60.3% vs de-vigged market 68.0%: 7.7-point divergence within the 12-point cap (blended to 47.2% at MODEL_WEIGHT=0.5).
  • Edge gate: model edge vs offered price is -5.3 pts (minimum 2). No allocation; a good side at a bad price is a bad bet.
  • Rule 4 flag: Erik Miller 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 0.279 trails league 0.315 by 0.036 (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): 91°F at first pitch: run environment x1.084. Applied to the paper totals pick; the staked board ignores weather entirely.

👁 Watch (market-proving, 0u): Under 9.5 (-113, LowVig.ag) · model 55.3% · edge +2.2 pts · divergence +4.2 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 9.5 (-113, LowVig.ag) — WIN (+0.89u paper).

No stake rode on this game. The lean and its failed gates above are the whole position: passing is a position too.
