Seattle Mariners vs Athletics Odds: Common Questions
Who has the best odds on Seattle Mariners vs Athletics?
At the latest scan LowVig pays the most on Seattle Mariners at -155, and Novig pays the most on Athletics at +153. Those are two different books more often than not, and the best number moves as books reprice, so check the table on this page before you bet rather than assuming one book wins both sides.

Right now 12 books price this side, and the spread between the best and worst of them is +153 at Novig versus +135 at Fliff. On a $100 bet that is $18.00 more in your pocket for the same wager, won or lost the same way. That difference is the entire reason this page exists.
Where did the Seattle Mariners vs Athletics line open?
Athletics opened +131 at BetOnline and is +153 now. We capture the opener once from the historical archive rather than inferring it, so the number on this page is the price that was actually posted, and the movement charts above plot every scan since.
