The Mariners added some much-needed power to their lineup Wednesday, acquiring Michael Morse from Washington in a three-team deal that moved catcher John Jaso from Seattle to Oakland.

The NL East champion Nationals reacquired pitching prospect A.J. Cole, dealt from Washington to Oakland 13 months ago in the trade for Gio Gonzalez. Washington also got minor league pitcher Blake Treinen and a player to be named.

Morse hit .291 with 18 home runs and 62 RBI last year in an injury-shortened season, playing mostly as a corner outfielder.

The deal clears up a logjam in the outfield for Washington and at designated hitter for Seattle.

The Nationals acquired speedy center fielder Denard Span from Minnesota and contemplated moving Morse to first base but then re-signed Adam LaRoche. They are set at the corner outfield spots with Bryce Harper and Jayson Werth.

Jaso, 29, batted .276 with 10 homers and 50 RBI last year but became expendable when Seattle obtained Kendrys Morales and Raul Ibanez, moves that shift Jesus Montero from a catcher-DH split to primarily behind the plate.

To open a roster spot for Jaso, Oakland designated catcher George Kottaras for assignment.
