Odds Breakdown & EV Calculations
#### 1. Moneyline
- Astros (-135):
- Implied Probability: 150 / (150 + 100) = 57.6%
- Adjusted Probability (Favorite Win Rate = 59%): (57.6% + 59%) / 2 = 58.3%
- EV: 58.3% > 57.6% → +0.7% edge.

Rangers (+135):
- Implied Probability: 100 / (135 + 100) = 42.4%
- Adjusted Probability (Underdog Win Rate = 41%): (42.4% + 41%) / 2 = 41.7%
- EV: 41.7% < 42.4% → -0.7% edge.

2. Run Line (Spreads)
- Astros -1.5 (-161):
- Implied Probability: 1 / 2.61 ≈ 38.3%
- Adjusted Probability (Favorite Win Rate = 59%): (38.3% + 59%) / 2 = 48.7%
- EV: 48.7% > 38.3% → +10.4% edge.

Rangers +1.5 (-300):
- Implied Probability: 1 / 1.5 ≈ 66.7%
- Adjusted Probability (Underdog Win Rate = 41%): (66.7% + 41%) / 2 = 53.8%
- EV: 53.8% < 66.7% → -12.9% edge.

3. Totals
- Over 8.5 (Even Odds):
- Implied Probability: 50%
- Actual Probability Estimate: Combined ERAs (3.58 + 3.31 = 6.89) suggest a low-scoring game. Under is more likely.

Under 8.5 (-110):
- Implied Probability: 1 / 1.909 ≈ 52.4%
- Actual Probability Estimate: 65% (based on ERAs and Astros’ 7.8 strikeouts/game).
- EV: 65% > 52.4% → +12.6% edge.

Best Same Game Parlay
Pick: Astros -1.5 (-161) + Under 8.5 (-110)
- Why?
- Astros -1.5 has a +10.4% edge due to their dominance as favorites.
- Under 8.5 has a +12.6% edge given the Rangers’ elite ERA and Astros’ stingy offense.
- Combined Implied Probability: 38.3% (Astros) × 52.4% (Under) = 19.9%
- Combined Actual Probability: 48.7% × 65% = 31.7% → +11.8% edge.

Parlay Odds Example (DraftKings):
- Astros -1.5 (-161) × Under 8.5 (-110) = +375 (4.75 decimal)
- Risk: $100 → Potential Payout: $375

Final Verdict
The Astros are a well-coached, high-ERA team facing a Rangers squad that’s mastered the art of not scoring. Pairing the Astros’ run line with the Under is a statistical no-brainer. The EV is sky-high, and the math doesn’t lie—unless it’s trying to impress Lance McCullers.
