---

Why This Parlay?
1. Boston Red Sox to Win (-250 Moneyline)
- Key Stat: Boston is a 1.33 decimal favorite (BetMGM), reflecting a 75.2% implied probability.
- Edge: The Red Sox rank 6th in MLB runs scored (457) and face a Rockies team 30th in ERA (5.82). Lucas Giolito (1.33 implied win probability) vs. Antonio Senzatela (3.4 odds) tilts the matchup.

1. Under 9 Runs (-110)
   - Key Stat: Rockies rank 26th in runs scored (21) and Boston’s pitching staff has a 3.95 ERA but 8.4 strikeouts per 9 innings.
   - Edge: The Under has gone 7 of 8 games in Boston’s last 10 games. The implied probability here is 54.3% (1.87 decimal odds), but BetMGM’s 1.87 price gives better value.

Parlay Odds & Payouts
- Combined Odds: 1.33 (Red Sox win) × 1.87 (Under) = 2.49 (decimal) → +149 (American).
- Risk vs. Reward: A $100 bet nets $149 profit if both legs hit.

Why Not the Spread?
While Boston’s -1.5 (-125) spread line is tempting (1.65 decimal), the Under 9 offers better value given the Rockies’ anemic offense. The Red Sox’s -2.5 (-200) line at BetMGM is too steep for the risk.

---

Final Verdict: This parlay balances Boston’s dominance and the Rockies’ weakness. The Red Sox’s offense and pitching staff should keep runs low, making the Under 9 a smart counterintuitive add to a heavy favorite.
