The Oakland A’s traded first baseman Yonder Alonso to the Mariners on Sunday, the team reported. In exchange, Seattle sent back outfield prospect Boog Powell.
Although the July 31 trade deadline has passed, teams can still deal players if they first pass through waivers. Alonso was claimed by the Mariners when the A’s tried to pass him through, reports Susan Slusser of the S.F. Chronicle, and Oakland chose to work out a swap rather than pulling him back and keeping him the rest of the year.
Alonso is in the middle of the best season of his career.
