Central Notes: Indians, Royals, Rios, Twins, Willingham, Cards, Peavy

There was some action on the shortstop front for the Indians today, as starter Asdrubal Cabrera left the game with lower back spasms, per Paul Hoynes of the Cleveland Plain Dealer (via Twitter). That would appear to be a minor injury, but the news coincided with the club’s decision to promote top prospect (and fellow shortstop) Francisco Lindor to Triple-A, as Hoynes tweets. Cleveland has indicated, however, that the move was unrelated. Of course, Cabrera has often been mentioned as a trade candidate — at season’s end if not at this year’s deadline — due in large part to the continued rise of Lindor, his presumed successor.

Here’s more out of the AL and NL Central:

• With the Royals focusing on adding a corner bat, one possibility that the club has considered is Alex Rios of the Rangers, reports Jon Heyman of CBSSports.com. Rios does have a six-team no-trade clause which, according to Cot’s on Contracts, includes Kansas City. His $13.5MM club option for next season is not cheap, but could potentially take the place of Billy Butler’s own $12.5MM option if the latter is dealt or has his option declined.
• The Twins appear to be prepared to sell, according to a report from MLB.com’s Rhett Bollinger. “We’re in a tough spot right now and we’ve been in a tough spot for four years,” said GM Terry Ryan. “So you have to listen. And that’s what we do.” 
• One prime trade candidate for the Twins is outfielder Josh Willingham, who is slashing .209/.357/.399 with eight home runs in 207 plate appearances as he prepares to hit the open market after the season. Two clubs to watch as possible suitors are the Reds and Pirates, tweets Darren Wolfson of 1500 ESPN.
• The Cardinals received some promising news on righty Michael Wacha, who could begin throwing again in two weeks after seeing improved MRI and CT scan results, reports Rick Hummel of the St. Louis Post-Dispatch. An early September return still appears the best case scenario, according to GM John Mozeliak. But Wacha’s health will not dictate the club’s trade deadline plans. “They’re independent of each other,” said Mozeliak. “That’s still something we can explore in the next eight to ten days.”
• One oft-discussed option for the Cardinals is veteran Red Sox starter Jake Peavy, who once seemed close to being moved but could now be held as Boston looks to make a late surge. St. Louis is still keeping Peavy on their “back burner,” a source tells Nick Cafardo of the Boston Globe (Twitter link), who notes that Peavy has put together three consecutive solid outings.
