The 2023 season was a roller coaster ride for the Seattle Mariners, who finished with an 88-74 record. They went from 1st place in the AL West Sept. 2 to missing the playoffs entirely after losing 16 of 27 games to finish the season.
The Mariners’ offseason started with them shipping out 3B Eugenio Suarez and LF Jarred Kelenic. They then brought in C Mitch Garver, 2B Jorge Polanco, RHP Gregory Santos and RHP Ryne Stanek in hopes of a stronger finish to the season this time around. Let’s analyze the Seattle Mariners’ World Series odds, along with their projected win total, playoff, division and AL odds as we make our expert MLB picks and predictions.
Seattle Mariners World Series odds
Provided by FanDuel Sportsbook; access USA TODAY Sports Scores and Sports Betting Odds hub for a full list. Lines last updated Sunday, March 24, at 10:51 p.m. ET.
Odds: +2000 (bet $100 to win $2,000)
Seattle has the 9th-shortest odds to win the World Series. The Los Angeles Dodgers (+320), Atlanta Braves (+450), and Houston Astros (+700) are the odds-on favorites to win it all, while Seattle is just behind the Toronto Blue Jays (+1800) and ahead of the Minnesota Twins (+2100).
At +2000, Seattle has an implied probability of winning the World Series of 4.76%, and to be profitable, you would only have to hit bets at these odds once every 20 times.
While most would be hesitant to back the Mariners to win it all after missing the playoffs last season, 3 of the last 7 World Series champs actually accomplished the same feat — the Texas Rangers in 2023, the Washington Nationals in 2019, and the Houston Astros in 2017.
If you have to access to a book with a better number, I would play this there. Otherwise, betting the MARINERS (+2000) to win the World Series is worth a small wager.

Seattle Mariners playoff odds
Will they make the playoffs: Yes -164 | No +126
The Mariners’ chances of making the playoffs Sept. 2 were 90.2%, according to Fangraphs.com. The Mariners moving forward will probably look a lot more like the team they were for the majority of last season, not like a team that lost 16 of the last 27 games.
CF Julio Rodríguez was 8th, tied with Arizona Diamondbacks LF Corbin Carroll, in offensive wins above replacement last season, and if he can continue to impact the game at this level, the Mariners should be priced higher to make the playoffs.
BET YES (-164).
Seattle Mariners win total
Over/Under: 87.5 (O: -108 | U: -112)
Will Seattle have a worse record than last season?
I’m surprised that the market is so down on the Marineres, especially since they got slightly better in the winter. There’s decent value at this number, especially if you believe Seattle can put together the same type of season it did last year without the bad luck at the end.
BET OVER 87.5 (-108).

To win AL West Division
- Houston Astros -115 (bet $115 to win $100)
- Texas Rangers +210 (bet $100 to win $210)
- Seattle Mariners +300 (bet $100 to win $300)
- Los Angeles Angels +4500 (bet $100 to win $4,500)
- Oakland Athletics +25000 (bet $100 to win $25,000)
Seattle’s implied probability of winning the AL West is 25%.
I’m not a fan of betting into these multi-way markets since they tend to have such a bad theoretical hold. They can be beat, but it’s very difficult. In a division with Houston and Texas, the last 2 World Series champs, Seattle should be getting a better number than +300.
PASS.
To win American League
Odds: +900 (bet $100 to win $900)
The market is pretty much painted +900 domestically. However, some of the offshore books with higher limits have this number floating between +792 and +840. There is definitely interest in the Mariners to make a deep run in the AL this season, and +900 is the best number you will find.
BET MARINERS (+900).
