SEATTLE (AP) — Matt Olson hit his 14th homer of the season in the second inning and added a key two-run single as part of Oakland’s big seventh inning, and the Athletics rolled to a 12-6 win over the Seattle Mariners. Olson’s opposite-field homer in the second inning off Seattle starter Marco Gonzales gave the A’s an early advantage. His hit in the seventh was part of a six-run inning as Oakland rallied from a 4-1 deficit. Manager Bob Melvin picked up his 799th career win with the A's, the most by any manager since the team moved to Oakland. Seattle’s bullpen that has been a strength most of the season imploded giving up 11 hits, 11 runs and five walks.
