### 3. Odds Breakdown & EV Calculations
Moneyline Implied Probabilities (American Odds):
- Detroit (-190): 190 / (190 + 100) = 65.7%
- Seattle (+180): 100 / (180 + 100) = 35.7%

Adjusted Probabilities (Using MLB Underdog Win Rate of 41%):
- Detroit (Favorite):
- Favorite Win Rate = 100% - 41% = 59%
- Adjusted = (65.7% + 59%) / 2 = 62.35%
- Seattle (Underdog):
- Adjusted = (35.7% + 41%) / 2 = 38.35%

EV Comparison:
- Detroit: 62.35% (adjusted) vs. 65.7% (implied) → Negative EV.
- Seattle: 38.35% (adjusted) vs. 35.7% (implied) → Positive EV.

### 4. Strategic Bet Recommendation
Bet the Seattle Mariners (+180).
- Why? The underdog EV is +2.65% (38.35% adjusted vs. 35.7% implied), suggesting the market underestimates their chances.
- Caveats:
- The Tigers’ 12-3 loss to Seattle last week is a red herring; Detroit’s overall dominance (5-1 season series) and Flaherty’s edge in this matchup tilt toward the Mariners needing a breakout.
- The Over/Under (8 runs) is a toss-up, but the Mariners’ power (Cal Raleigh, 81 RBI) could exploit Flaherty’s 4.3 BB/9.

### Final Verdict
While the Tigers’ record and recent form scream “favorite,” the Mariners’ 41% underdog win rate in MLB and the Tigers’ inflated implied probability (-190) create a clear value play on Seattle. Bet the +180 underdog to exploit the market’s overconfidence in Detroit’s invincibility.
