Seattle Mariners vs. Detroit Tigers: The Ultimate Same-Game Parlay Play
By The Handicapper with a Calculator and a Sense of Humor

---

Key Statistics: A Tale of Two Pitchers and a High-Scoring Forecast
- Detroit Tigers (59-35): The AL’s best team, led by Tarik Skubal (2.02 ERA, 148 Ks in 116 IP). They’ve won 44 of 63 games when favored, a 69.8% clip that screams “bookmaker’s nightmare.”
- Seattle Mariners (48-45): Luis Castillo (3.37 ERA, 87 Ks) anchors the rotation, but the M’s are just 14-32 as underdogs (43.8% win rate).
- Head-to-Head: Detroit won 2 of 3 meetings in April. The model projects a 9.5-run average, with Skubal and the Tigers’ offense (led by Riley Greene, 22 HRs) primed to dominate.

---

Injuries/Updates
- No major injuries reported for either team. Skubal and Castillo are both healthy, so this is a straight pitching duel.
- The Tigers’ recent loss to Tampa Bay (7-3) was a fluke; they’ve been a high-octane machine all season.

The Best Same-Game Parlay: Detroit -1.5 & Over 7.0
Why This Combo?
1. Detroit -1.5: Skubal’s 2.02 ERA and the Tigers’ 69.8% win rate as favorites suggest they’ll cover the spread. Adjusted probability = 56.1% (vs. implied 52.4%).
2. Over 7.0 Runs: The model’s 9.5-run projection makes this a 75%+ lock (vs. implied 52.4%).

Combined Implied Probability: 52.4% * 52.4% = 27.5%.
Actual Probability: 56.1% * 75% = 42.1%.
EV = 42.1% - 27.5% = +14.6%.

Odds:
- FanDuel: Detroit -1.5 (-110) + Over 7.0 (-110) = +210 (combined).

Final Verdict: Bet Like a Stathead, Win Like a Showman
- Take Detroit -1.5 & Over 7.0. Skubal’s dominance and the Tigers’ offensive firepower make this parlay a statistical slam dunk.
- Avoid the Mariners +1.5: Their 32.7% adjusted win rate is still a dog’s dinner against a team with a 59% favorite win rate.

Bonus Joke: If the Tigers don’t score 8 runs, I’ll eat my calculator… and your skepticism.

Play it at FanDuel or BetMGM for the best odds. And remember: In baseball, the Over always wins when the model says “9.5.” 🎯⚾
