Diamondbacks ace Dan Haren will not be traded, according to Ken Rosenthal and Jon Paul Morosi of FOX Sports. A D'Backs official put it bluntly: "We're not trading him. We don't want to change our core."
Haren signed an extension in August of last year taking him through 2012 with a club option for 2013. The 28 year-old leads the NL with a 2.14 ERA in 143 innings.
Back on June 30th, Rosenthal wrote that the Angels inquired on Haren but the D'Backs "declined to engage in serious discussions."
