### Why This Parlay?
1. Seattle Mariners Moneyline (-159):
- The Mariners are the clear favorite, with a 52.9% win rate when favored. Their offense (4.6 R/G) vs. the Royals' last-place defense (3.3 R/G) gives them a strong edge.
- Price: 1.59 decimal (implied probability: ~62.9%).

2. Over 7.5 Runs (Even Money):
- The Mariners average 4.6 runs per game, while the Royals allow 3.3. Combining their offensive firepower with Kansas City’s porous pitching (28th in MLB in ERA) makes the Over a logical pick.
- Price: 2.0 decimal (implied probability: 50%).

### Combined Logic:
- Implied Probability: 62.9% (Mariners win) × 50% (Over) = 31.4% chance to win the parlay.
- Total Return: A $100 bet nets $218 profit (odds: 3.18).

### Key Stats:

- Offense vs. Defense Matchup: Seattle’s 4.6 R/G vs. KC’s 3.3 R/G.
- Starting Pitchers: George Kirby (Mariners) vs. Michael Wacha (Royals).

Avoid Other Parlays:
- The Royals (-150) + Under 7.5 (2.0) is a poor value given their 3.3 R/G offense and the Mariners’ high-scoring tendencies.

Verdict: This parlay leverages Seattle’s dominance and the game’s high-scoring potential for maximum value. Go with BetMGM for the best odds. 🎯
