FOX Sports' Jon Paul Morosi and Ken Rosenthal report that the Mariners are close to acquiring Michael Morse.
The Washington Post's Adam Kilgore says it's a three-team deal that will send A.J. Cole to the Nats and John Jaso to the A's. Morse, who is under contract for $6.75 million in 2013 before hitting free agency, became expendable after the Nats traded for Denard Span and re-signed Adam LaRoche. The 30-year-old has batted .297/.343/.515 with 49 homers over the last two years for Washington. He'll slide into a corner outfield spot.
