The Washington Nationals traded Michael Morse to the Seattle Mariners in a three-team trade Wednesday night, reports the Washington Post.
The deal will also send Mariners catcher John Jaso to the Oakland Athletics and minor-league right-handers A.J. Cole and Blake Treinen and a player to be named from Oakland will go to the Nationals.
Morse became expendable when the team re-signed first baseman Adam LaRoche last week. Morse, 30, hit .291 with 18 home runs and 62 RBI in 102 games with the Nationals last season. He is scheduled to make $6.75 million next season.
