The Colorado Rockies are mildly interested in free agent starting pitchers Jeff Karstens and Brandon Webb, reports Troy Renck of the Denver Post.

Webb, one of the best pitchers in the National League before seeing his career end, at least for now, on opening day in 2009, represents an extremely low-risk and potentially high-reward arm. While Rockies fans understandably want to see the club do more than go after another reclamation project, one has to admit that the team has enjoyed some success in that department, as Renck notes.
