With starting pitching the Cubs’ primary focus again this winter, they already have expressed interest in Athletics right-hander Brandon McCarthy, who was having a good season until suffering a skull fracture when hit by a line drive in September. He underwent surgery and didn’t pitch again this season but appears to be healthy enough for a comeback effort in 2013.
Brewers free agent Shaun Marcum, a 2009 Tommy John surgery graduate who missed two months in 2012 with elbow tightness, is another buy-low candidate the Cubs are eyeing — and a guy whose character they know well through manager Dale Sveum and pitching coach Chris Bosio.
Not sure about the wording on Marcum meaning that they plan to express interest or already have. Also, who knows if he isn't just piggybacking on that SF report about McCarthy that, given the wording, wasn't all that solid, IMO.
