Prop Bets: St. Louis Cardinals VS Seattle Mariners 2025-09-10
Seattle Mariners vs. St. Louis Cardinals: A Game of "Why So Serious?"
The Seattle Mariners (-234) are here to remind us that being a favorite is just a fancy way of saying "we’re not giving you much of a chance to win, Cardinals." The Cardinals (+191) will try to defy their underdog status, but their 38-38 record as underdogs this season suggests they’re more "I’ll have the same" than "I’ll take the risk."
Why the Mariners Might Win:
- Logan Gilbert (4-6, 3.61 ERA) and Michael McGreevy (6-3, 3.61 ERA) are like identical twins who both forgot to bring their best stuff. But Gilbert’s 151 strikeouts in 109⅔ innings give Seattle a slight edge in the "who’s less likely to throw a wild pitch?" contest.
- The Mariners have won 83.3% of games when favored by -234 or shorter this season. That’s not a trend—it’s a threat.
- Cal Raleigh (53 HRs, 113 RBI) is a home run machine with a "Over 0.5 HR" prop at +215. Bet on him to "clear the bases" literally and figuratively.
Why the Cardinals Might Win:
- The Cardinals have a 48.7% win rate as underdogs, which is about the same as your chances of finding a fair call from a first-base umpire. Still, their 72-72 Over/Under record means they’ll likely keep this game chaotic.
The Over/Under: 7.5 Runs (-110 each)
With both teams averaging 4.3-4.7 runs per game and the starters’ ERAs tied at 3.61, this feels like a "let’s see who breaks first" scenario. Take the Over—because nothing says "baseball" like a 10-9 slugfest.
Player Props to Watch:
- Cal Raleigh HR Over 0.5 (+215): The Mariners’ slugger has 53 HRs on the season. If he doesn’t go deep, the Mariners’ offense might as well pack it in.
- Julio Rodriguez HR Over 0.5 (+480): The "King of the Moonshot" has 53 HRs too. At +480, it’s a long shot, but hey, someone’s gotta hit one.
Final Verdict:
The Mariners are the safer bet, but the Cardinals’ underdog magic could spark a "Cinderella" moment. Either way, this game is a must-watch for anyone who enjoys seeing pitchers try not to get shelled.
Prediction: Seattle Mariners 5, St. Louis Cardinals 3 (Mariners -1.5, Over 7.5). And no, the Cardinals, you’re not "close"—you’re a +191 underdog. Own it.
Note: Props to Cal Raleigh for making HR odds look like a part-time gig. 🎉⚾
