If youโ€™re in Washington and interested in odds for other teams, check out:ย 

Seattle Mariners Futures Odds

Will the Mariners win the AL West? Will they win the AL pennant? How many home runs will a certain player hit this season?

For example: If you bet $40 on the Mariners (+600) to make the postseason, the bet would settle when Seattle is eliminated or when they clinch a postseason berth.

Seattle Mariners Run Line

The run line is baseballโ€™s version of the spread. Whatโ€™s the final scoring margin of the game?

For example: If you bet $80 on the Mariners -1.5 (+210) against the Oakland Athletics, Seattle must win the game by at least two runs.ย 

Alternatively, if you bet $80 on the Mariners +1.5 (-120) against the New York Yankees, Seattle must lose by one run (or win the game).

Seattle Mariners Moneyline

Will the Mariners win the game?ย 

For example: If you bet $75 on the Mariners -300 against the Pittsburgh Pirates, Seattle must win the game (in nine innings or extra innings).

Seattle Mariners Over/Under Total

How many combined runs will be scored by both teams in the matchup?ย 

For example: If you bet $30 on over 7.5 (-110) in their game against the Kansas City Royals , the teams must combine for at least eight runs.ย 

Alternatively, if you bet $40 on under 7.5 (-110), the teams must combine for seven or fewer runs.

If the combined run total is the same as the over/under total, the bet is a push.

Seattle Mariners Parlays

You can combine bets and other bets โ€” baseball or another sport โ€” into one parlay.

For example: If you bet $20 on a two-leg parlay with the Mariners moneyline (-180) vs. the San Francisco Giants and over 7.5 (-110) in the Baltimore Orioles-Tampa Bay Rays game, both must hit for the bet to cash.

If one bet is a push, itโ€™s eliminated from the parlay, and odds (and payout) are recalculated without that leg.
