According to Phil Rogers of the Chicago Tribune, the Cubs have some interest in adding Twins’ starter Carlos Silva for some rotation insurance. Despite the lack of strikeouts, I think Silva could put up an ERA below 4.50 in the NL Central.
La Velle E. Neal III of the Minneapolis Star-Tribune mentions the Cubs, Braves, Mets, and Diamondbacks as teams that like Silva. He could be used as a starter or reliever.
