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.
The run line is baseballโs version of the spread. Whatโs 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).
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).
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.
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, itโs eliminated from the parlay, and odds (and payout) are recalculated without that leg.
