The Diamondbacks "are more focused on trades than free agents" in their search for a starting pitcher, according to a source of Ken Rosenthal and Jon Paul Morosi of FOX Sports. The writers suggest the D'Backs will look for a cheap back-end rotation type, speculating on non-tender candidates Dave Bush, Brian Tallet, and Tim Redding. It sounds like the D'Backs don't want to give up a ton in trade, as they're reluctant to meet the asking price for Edwin Jackson and haven't inquired on Pirates starters Paul Maholm and Zach Duke.
Back on November 12th, we named about 30 potentially available starters, including Tallet and Bush.
