SEATTLE -- The Oakland Athletics clinched their first playoff berth since 2014, then beat the Seattle Mariners 7-3 Monday night behind Khris Davis' major league-leading 46th home run.
Jonathan Lucroy, Jed Lowrie and Matt Chapman also homered for the A's, assured no worse than a wild-card berth.
Oakland was one out into the game when Tampa Bay was eliminated with a 4-1 loss to the New York Yankees. The A's went on to win after Chapman broke a 3-3 tie with a two-run drive in the seventh off Shawn Armstrong (0-1).
