Seattle won for the seventh time in eight games to catch Detroit in the wild card race. Seattle got another solid performance from veteran Chris Young, who earned his 11th victory, and the Mariners also continued their recent offensive punch.
Seager's 18th homer gave Seattle a 2-1 lead in the fourth. Ackley followed an inning later, going to the opposite field to drive in a pair. Morales capped the night with his first homer since being acquired by the Mariners in a trade with Minnesota in late July.
