Prop Bets: Seattle Mariners VS Kansas City Royals 2025-09-16
Mariners vs. Royals: A Tale of Power vs. Perseverance
The Seattle Mariners, baseball’s answer to a wrecking crew, will face the Kansas City Royals in a September showdown that’s as much about pride as it is about playoff positioning. With the Mariners’ offense averaging 4.7 runs per game and the Royals’ pitching staff clinging to a 3.73 ERA (fourth in MLB), this game is a numbers game waiting to happen.
Why the Mariners Should Win:
- Logan Gilbert’s 3.54 ERA and 159 strikeouts in 114⅓ innings this season make him a thorn in the Royals’ side. The underdog team has struggled against left-handed starters, scoring just 3.2 runs per game in such matchups.
- The Mariners’ Julio Rodriguez (+160 Over 1.5 hits) and Cal Raleigh (-205 Over 0.5 HR) are primed to punish any defensive lapse. Rodriguez’s .321 OBP and 216 HRs this season? A nightmare for Kansas City’s infielders.
- The Royals’ Michael Wacha (9-11, 3.83 ERA) faces a lineup that’s hit 21 HRs against right-handed pitching this month. His 3.5 K/9 (18.5 Over -156) might not be enough to survive a barrage of longballs.
Why the Royals Might Survive:
- Kansas City’s defensive efficiency (6.8 K/9, 3rd in MLB) could snuff out Seattle’s rally attempts. Their 2.5-team total Under (-145) is a sneaky play if Wacha keeps the game close.
- Jac Caglianone’s 0.5-HR Over (+380) is a longshot, but his .240 BA and 14 HRs in 2025? A gamble worth taking if you’re feeling lucky.
The Verdict:
The Mariners’ bats are a wrecking ball, and the Royals’ pitching staff might as well be on vacation. Take Seattle -1.5 (-140) and the Over 8.5 runs (1.95). And if you’re feeling spicy, back Cal Raleigh Over 0.5 HR (-205)—he’s hit 5 HRs in his last 10 games.
Final Score Prediction:
Seattle 6, Kansas City 3. Because even a blind squirrel finds acorns sometimes, but the Mariners? They find HRs.
