Prop Bets: Colorado Rockies VS Seattle Mariners 2025-09-23

Seattle Mariners vs. Colorado Rockies: A Tale of Two Teams (and a Few Over/Unders)
Predicted September 24, 2025 — 1:41 AM ET

The Colorado Rockies, fresh off a season that’s been about as exciting as a rain delay, will face the Seattle Mariners, who’ve been swinging like they’re auditioning for a Marvel superhero. With the Rockies at +325 on the moneyline and the Mariners as -136 favorites, this is a mismatch that even a blind squirrel could’ve predicted. But hey, let’s not let the Rockies’ offense (or lack thereof) rain on our parade. Let’s dive into the chaos.

### Key Stats & Props
1. Julio Rodriguez, Mariners’ Star: The kid’s got a -115 line on Over 1.5 total bases. That’s not just a bet—it’s a certainty. Rodriguez has been hitting so hard, even the Rockies’ pitcher might tip his cap. Implied probability? A solid 53.3%. If you’re betting on Rodriguez, you’re basically just writing a check to yourself.

2. Cal Raleigh: Another Mariners’ batter with a -115 Over 1.5 total bases line. If Raleigh’s not hitting doubles or triples, I’d check if he’s been replaced by a robot. Both he and Rodriguez are so locked in, it’s like they’ve got a “Baseball GPS” set to “Dominance.”

3. Total Runs (8.0): The Over/Under is a flat 1.91 for both sides. With the Mariners’ offense and the Rockies’ pitching (which is about as reliable as a third grader holding back a sneeze), this game could blow the roof off T-Mobile Park. Take the Over unless you enjoy watching Rockies’ fans cry into their beer.

4. Randy Arozarena’s Home Run Hopes: At +450 for Over 0.5 HRs, Arozarena’s got a 19% implied chance to go deep. If he doesn’t, the Rockies’ pitcher might as well pack up and go home.

### Why the Rockies Should Pack Up
The Rockies are +3.25 on the moneyline, which is basically the sportsbook’s way of saying, “We’re giving you free money to bet against these guys.” Their lineup? A mix of “meh” and “please just make it stop.” Meanwhile, the Mariners are -136 favorites, which means the implied probability of their win is 57.4%. That’s not a bet—it’s a mathematical inevitability.

### Final Verdict
This game is a Mariners’ coronation. Bet on Rodriguez and Raleigh to rack up the bases, take the Over on runs, and laugh all the way to the bank while the Rockies’ fans sip their lukewarm beer. As for the Rockies? They’ll need a miracle, a time machine, and a mercy rule.

Final Score Prediction: Mariners 7, Rockies 3 (because even the Rockies’ manager deserves a break from this).

Disclaimer: This prediction is not financial advice. It’s also not a guarantee that the Rockies will finally trade for a competent starting pitcher. That’s on you, Denver. 🍻⚾
