NL Central Notes: Stewart, Cole, Soler

The five NL Central clubs' possible trade deadline moves are highlighted by Grantland's Jonah Keri in his weekly MLB power rankings.  The Cubs have several trade chips to sell while the Brewers may move some relievers at the deadline but wait until the offseason to decide if they're going to truly rebuild, Keri writes.  The Pirates have made deadline additions in each of the past two seasons and have a few clear needs now, though Keri says the current team is good enough to get just a minor upgrade or maybe even stand pat.  The Reds and Cardinals both need bullpen help, with Keri noting that the Cards are deep enough that they can get by with Pete Kozma at shortstop.

Here's the latest from around the division…

• The Cubs are close to parting ways with Ian Stewart, sources tell CBS Sports' Jon Heyman, with "the resolution allowing him to move to another organization is expected to come within a couple of days."  The move seemed inevitable after Stewart was suspended by the team after he criticized the Cubs organization in a Twitter rant.  Heyman wasn't sure if any financial concessions are involved in the move though since Stewart's deal is guaranteed, he isn't obligated to give back any of the approximately $1MM remaining on his 2013 contract.
• Gerrit Cole may get sent down to Triple-A once A.J. Burnett and Wandy Rodriguez return to the Pirates rotation, GM Neal Huntington hinted during his Sunday radio program (passed on by Rob Biertempfel of the Pittsburgh Tribune-Review).  Since Cole and Jeff Locke are the only Bucs starters with minor league options remaining, Huntington said “there's a business component to it, as far as keeping our depth….if we need another starter (due to injury) later, it may make sense to send Gerrit back so we have a sixth quality starter.”  While Huntington said that Cole's possible Super Two status won't be a factor in the team's decision, a demotion would guarantee that Cole doesn't receive another year of arbitration eligibility.
• Yasiel Puig's instant stardom has raised expectations for the Cubs' own Cuban prospect Jorge Soler, though CSN Chicago's Patrick Mooney outlines how the Cubs are taking a more measured approached to Soler's development.
• MLB.com's Jenifer Langosch also expects the Cardinals to get some bullpen help before the trade deadline, though it's likely to be a smaller-name reliever than Jonathan Papelbon, who isn't a fit in St. Louis for several reasons.  Langosch also covers a few other Cards topics as part of this reader mailbag piece.
