While the Mariners recently looked to be clear sellers in this year's trade market, the team's recent eight-game winning streak and offensive explosion looks to have changed their position. Jon Heyman of CBS Sports reports that teams who have checked in on the Mariners have been told they're not sellers at this time (Twitter link).

No team has scored more runs than the Mariners this month, which is an encouraging sign for a team whose rotation is fronted by Felix Hernandez and Hisashi Iwakuma. The Mariners have a number of veterans on one year deals, including Kendrys Morales, Mike Morse, Joe Saunders, Oliver Perez, Raul Ibanez and Jason Bay, many of whom were frequently mentioned as trade candidates.

Heyman tweets that in particular, there's little belief that Seattle would move Morales, as they plan on extending a qualifying offer to him at season's end. He's been terrific for the M's since coming over from the division rival Angels this offseason, hitting .282/.341/.466 with 15 homers.

Recently, Larry Stone of the Seattle Times noted that general manager Jack Zduriencik wasn't planning on being aggressive at the trade deadline because the franchise needed to show some progress to fans and couldn't afford another 90-loss season. Obviously, that's doubly true for Zduriencik himself, as his job has been rumored to be in jeopardy. At the time that piece was written, Stone thought Perez would certainly be moved, and added that the Mariners could make small trades of Brendan Ryan and Endy Chavez. It appears now that the Mariners, who are 8.5 games back from a Wild Card spot, will hold steady.
