Player Breakout:

• Atlanta, Boost 0%, Targets: Matt Olson / Ronald Acuña Jr., Reason: PCM inactive; only 55.6% opposite-hand exposure against Imanaga, 21.9% / 15.5% • Chicago, Boost 0%, Targets: Pete Crow-Armstrong / Michael Busch, Reason: PCM inactive; 33.3% opposite-hand exposure against Ritchie, 24.2% / 16.1% • HRCF: N/A — starter HR/9 unavailable • Most likely HR: Pete Crow-Armstrong — 24.2%, supported by 41 HR in 563 AB and .574 SLG. — EDGE SUMMARY • CHC ML −144 — Model 56.1% vs de-vigged market 56.7% → VES −0.30 → No Edge → 0.00u • ATL ML +122 — Model 43.9% vs de-vigged market 43.3% → VES +0.30 → No Edge → 0.00u • ATL +1.5 — 69.1%; opposite run-line price N/A → VES N/A • Total 8.0 — Over 53.6%; market total ambiguous → barred • Rule 2b: Active on both teams because R/G inputs are derived • DQS: 51/100 • G7: Breach +1.61 • §3 artifact ceiling: Clean; sim-to-market gap only 0.3 points • No qualifying model-market value. — INSIGHTS • strengths: Chicago owns the starting-pitcher advantage through Imanaga and the stronger projected offense. Pete Crow-Armstrong has the matchup’s strongest power profile. Atlanta owns the superior bullpen projection by approximately 0.56 RA9 and has an exceptional 51-27 road record. • weaknesses: Both offensive R/G inputs are derived, Atlanta has only 3 of 5 recent games, Chicago has 4 of 5, both lineups are projected, starter HR/9 and WHIP are unavailable, wind is unavailable at Wrigley, and the total market is ambiguous. • winning edge: Chicago’s starter/offense advantage is partially offset by Atlanta’s bullpen edge. The resulting 56.4% simulation probability almost exactly matches the 56.7% de-vigged market probability. • Volatility: PCM inactive, BTM inactive, HRCF unevaluable, bullpen conditions fresh. The largest unknown volatility input is Wrigley wind. — SPORTSBOOK LIABILITIES: • Betting splits: N/A • Handle: N/A • Line movement: N/A • Highest liability outcomes from model distribution: narrow Chicago win, especially CHC by 1; high-scoring outcomes remain elevated relative to the posted 8.0 total, but G7 and missing wind prevent treating that as actionable. — 99.99% Parlay:

• A true 99% five-leg parlay is not supported by the simulation.

Step 1. High confidence 5 leg parlay: • ATL +3.5 • Over 4.5 • Pete Crow-Armstrong 1+ Hit • Michael Harris II 1+ Hit • Nico Hoerner 1+ Hit • True correlated joint probability: 18.4% • Fair odds: +443 • Naive probability: 19.4% • Correlation effect: −1.0 percentage point

Step 2. Same legs adjusted to 99% confidence: • Not achievable without misrepresenting the model probabilities. • Maximum-confidence correlated build supplied by the simulation: ATL +3.5 + Over 4.5 + Pete Crow-Armstrong 1+ Hit • True joint probability: 43.8% • Fair odds: +128 • This remains materially below 99%. — Raw Prediction: • ML: CHC −144 — 56.1% blended / 56.4% simulation • ML: ATL +122 — 43.9% blended / 43.6% simulation • Spread: ATL +1.5 — 69.1% • Spread: CHC −1.5 — 30.9% • Alt Spread 1: CHC +3.5 — 85.1% • Alt Spread 2: ATL +4.5 — 83.9% • Alt Spread 3: ATL +2.5 — 78.6% • Alt Spread 4: ATL +1.5 — 69.1% • Alt Spread 5: CHC +1.5 — 69.1% • Alt Total 1: Over 4.5 — ~86%, but totals family barred • Alt Total 2: N/A • Alt Total 3: N/A • Alt Total 4: N/A • Alt Total 5: N/A • Strikeouts: Imanaga Over 3.5 — ~83% • Strikeouts: Imanaga Over 4.5 — ~71% • Strikeouts: Imanaga Over 5.5 — ~55% • Hits: Tyrone Taylor 1+ — 81.9% ⚠ tiny sample • Hits: Michael Harris II 1+ — 69.7% • Hits: Pete Crow-Armstrong 1+ — 69.0% • Runs: Pete Crow-Armstrong 1+ — 50.8% • Home Run: Pete Crow-Armstrong — 24.2% • Home Run: Matt Olson — 21.9% • Total Bases: Pete Crow-Armstrong 2+ — 62.6% • Total Bases: Matt Olson 2+ — 55.5% • Hits Allowed: Imanaga ~5.3 • Hits Allowed: Ritchie ~4.7 • Hits+Runs+RBIs: Pete Crow-Armstrong 2+ — 68.8% • NRFI: 50.1% • YRFI: 49.9% • Real probabilities retained; no artificial adjustment to 80% where the underlying model probability is below 80%.

Recommendation & why • No qualifying bets. • DQS 51 is nineteen points below the required 70 floor. • Rule 2b binds on both offenses. • Chicago ML has essentially no model-market discrepancy: 56.1% model versus 56.7% fair market. • The total is barred by a +1.61 G7 breach, ambiguous market posting, missing wind and totals-discipline restrictions. • The strongest ≥80% model outputs are CHC +3.5 at 85.1%, ATL +4.5 at 83.9% and Imanaga Over 3.5 K at approximately 83%, but the game-level data-quality gate prevents them from becoming qualifying bets. —END OUTPUT—
