Seattle Mariners vs. Oakland Athletics: A Prop Bet Bonanza
August 23, 2025 | 10:11 PM ET | Safeco Field

The Setup:
The Seattle Mariners (-230) roll into Oakland like a freight train, favored to stomp the Athletics (+190) into the dirt. The Mariners are 6-2 in their last 8 games as favorites, and the A’s? Well, they’re 1-6 as underdogs this season. Let’s just say the A’s are about as likely to win this game as a vegan at a steakhouse.

Key Stats:
- Mariners: 4.5 runs/game (11th), 180 HRs (4th).
- Athletics: 3.95 runs/game (29th), 178 HRs (10th).
- Pitchers: Bryan Woo (Mariners, 2.90 ERA) vs. Luis Morales (Athletics, 4.50 ERA).

Prop Bets to Watch:
1. Cal Raleigh (Mariners) Over 1.5 Total Bases (-115):
The Mariners’ slugger has 77 HRs this season. At -115, this is a 54.7% implied chance. Bet him to mash.

1. Julio Rodriguez (Mariners) Over 1.5 Hits (-160):
   The “King of Clutch” has a .667 AVG in his last 7 games. 61.5% implied odds? Take the over.

1. Luis Morales (Athletics) Under 4.5 Strikeouts (-110):
   Morales has struck out 7+ batters just once in his last 5 starts. Fade the A’s pitcher.

1. Randy Arozarena (Mariners) Over 1.5 Home Runs (+120):
   The “Lightning” has 15 HRs in 2025. At +120, this is a 45.5% shot. Swing for the fences.

Why the Mariners Win:
- Bryan Woo’s ERA: 2.90 (trust the process!).
- A’s Hitting: Oakland’s .228 AVG is worse than a toddler’s aim.

Why the A’s Might Survive:
- Miracle on Grass: The A’s have a 44.3% win rate as underdogs… but that’s about as reliable as a broken umbrella in a hurricane.

Final Verdict:
The Mariners are a -230 machine, and the A’s are a +190 long shot. Take Cal Raleigh’s total bases over and Julio Rodriguez’s hits over. And if you must bet the game, fade the Athletics. Unless you enjoy losing money and bad coffee—then go for it.

Prop Pick:
Cal Raleigh Over 1.5 Total Bases (-115) – Because even if he strikes out, he’ll likely hit a moonshot to tie the game.

Implied probabilities calculated using American odds. Mariners’ 54.7% win chance vs. Athletics’ 45.3%—because math never lies (unlike the A’s offense).
