Rich Harden is drawing interest from teams that would use him as either a starter or a reliever, according to Major League sources. Teams aren't questioning the free agent right-hander's stuff, but he has a long history of injury and the belief is that he may stay healthy with a lighter workload. Harden, 30, spent last season with the Athletics, but was sidelined until July 1 with a strained lat muscle on his right side.
