Triple-A Iowa third baseman Ian Stewart faces a fine and possible suspension by the Chicago Cubs for his Twitter rant about his status in the organization.

But he will not be released, as Stewart suggested himself during a late night tweet to his followers.

The Cubs were upset about Stewart’s comments, but would not say what the punishment would be.

“We spent the entire morning dealing with an issue that doesn’t help us get better as an organization,” Cubs general manager Jed Hoyer said. “That’s not how we want to spend our time. What he did was really unprofessional and there are going to be consequences. Beyond that, I’m not going to comment.”

The Cubs suspended Milton Bradley for negative comments he made to the Daily Herald in September of 2009.

After going 1-for-3 with an RBI double Monday night at Triple-A Iowa, Stewart vented his frustration on Twitter, blaming Cubs manager Dale Sveum for his status and saying the organization is letting him “rot” and “might as well release me.”

Stewart’s late-night Twitter rant began when a fan tweeted him and asked if there was “any word when you’re heading back to Chicago.” Stewart replied: “Probably never.”

Stewart is hitting .164 at Iowa with a .279 on-base percentage, four home runs and 19 RBIs in 110 at-bats. He also had a three-home-run game on June 8. Stewart was sent to Iowa on a minor league rehab stint in April after injuring his quad in an intrasquad game in February, after missing the final four months of 2012 due to left wrist surgery. But the Cubs eventually optioned him to Iowa, where he’s been playing sporadically.

Stewart, a prolific tweeter, was replying to tweets from followers, and explained to one his reasoning for saying he’s "probably never” returning to the Cubs: “I said that because the Cubs are done with me. There (sic) going to let me ROTT (sic) in AAA all season and then non tender me after.”

When someone told Stewart to “just keep grinding ... and rake,” he made reference to Cubs third baseman Luis Valbuena by responding: “I honestly believe if Valbuena were to get hurt they wouldn’t call me up. Back up. Just MHO.”

One person tweeted Stewart to say he was “worthless” and should “quit baseball.” Stewart replied: “why would I quit. I’m making 2 mill in AAA like u would give that up by quitting.”

Stewart was non-tendered last December but re-signed for $2 million. If the Cubs release him, they’re obligated to pay the entire salary.

Stewart also tweeted: “I meant they might as well release me since I have no shot at a call-up.”
