  • Mariners Futures

    Think the Mariners are going to go all the way? See a pennant in their future? These are the latest odds from bookmakers on Seattle taking home the AL West crown, the AL Pennant and the World Series. A bet on these futures only cashes in if the Mariners hit those milestones and can pay big, as a 100 dollar bet on Seattle to win the World Series would net the bettor 10,000 dollars.
