NL West Rumors: Carroll, Diamondbacks, Harang

The Giants and Diamondbacks are buyers; the Rockies, Dodgers, and Padres are sellers.  The latest:

• The Diamondbacks have some interest in Rafael Furcal, tweets Jack Magruder.
• Diamondbacks GM Kevin Towers says it's 50-50 he makes a deal, tweets Jack Magruder of FOX Sports Arizona.  Towers does not expect a deal to break this evening.  He's hopeful teams will accept Arizona's second and third-tier prospects, tweets Nick Piecoro of the Arizona Republic. 
• The Dodgers' talks about trading infielder Jamey Carroll have died, tweets Dylan Hernandez of the L.A. Times, while there's a touch of interest in Furcal.  Paul Hoynes of the Cleveland Plain Dealer adds that the Dodgers' talks with the Indians have grown cold, so Carroll and Hiroki Kuroda won't be going to Cleveland.
• Clayton Richard's season-ending shoulder surgery is not a factor in whether the Padres trade starter Aaron Harang, tweets Dan Hayes of the North County Times.
