A source tells FOXSports.com that the Mariners are shifting into "sell mode," with Jarrod Washburn and potentially Mark Lowe, Sean White and Brandon Morrow available.

"They're about ready to do some things," an official of one contender said. With the Mariners now seven and a half games out of a playoff spot, trading Washburn would serve them well, but there is little incentive to giving up on former first-round pick Morrow, which the article acknowledges.
I'd jump all over grabbing Morrow if he is indeed available.
