Heading into Thursday's AL West matchup between Oakland vs Seattle, the Mariners are the heavy favorite on the moneyline. Even though Adrian Martinez was solid in his only other appearance, this came back on May 10th. I recommend taking the Mariners on the runline, as Logan Gilbert should have no problem vs Oakland's lineup.
