### Odds Breakdown & EV Calculations
Moneyline Odds (Decimal):
- Detroit Tigers: 1.44 → Implied Probability = 69.4%
- Seattle Mariners: 2.88 → Implied Probability = 34.7%

Adjust for Historical Context:
- Underdog Win Rate (MLB): 41%
- Favorite Win Rate: 100% - 41% = 59%

EV Adjustments:
1. Tigers (Favorite):
- Split difference between implied (69.4%) and favorite win rate (59%):
Adjusted Probability = (69.4% + 59%) / 2 = 64.2%
- EV = 64.2% vs. Implied 69.4% → Negative EV.

2. Mariners (Underdog):
- Split difference between implied (34.7%) and underdog rate (41%):
Adjusted Probability = (34.7% + 41%) / 2 = 37.9%
- EV = 37.9% vs. Implied 34.7% → Positive EV.

### Betting Strategy & Recommendation
- Mariners (+288 implied American odds) offer positive EV (37.9% adjusted vs. 34.7% implied). Their 43.8% underdog win rate this season further validates their value.
- Tigers (-202) are overvalued by the market. While their 69.8% favorite win rate is impressive, the EV math shows they’re priced as a 64.2% chance, not 69.4%.

Play the Underdog:
Bet the Seattle Mariners (+288). The Mariners’ historical underdog resilience (43.8% win rate) and the Tigers’ inflated line create a clear edge.

Bonus Angle: Consider the Over 7.0 Runs (-110). With both teams averaging 5.1 and 4.8 runs per game, and a combined 9.9 RPG in their last 10 meetings, the Over has 53% implied probability vs. 51% historical average.

Final Verdict:
The Tigers are a powerhouse, but the Mariners are a sneaky-good underdog play. Don’t let the line fool you—Seattle’s got pop, and the EV is on their side. Swing for the fences with the Mariners! 🐟🔥
