Well, they didn't introduce him slowly in 2002, and shut him down in late August because he was complaining about shoulder soreness. It was 2003, with Dusty "Pitchers are my playthings" Baker where he was amped way the heck up. So Prior's been complaining of soreness going on his fourth year now. All of this may not be the Cubs use of him. He may just be susceptible to soreness that needs to be accurately addressed. Prior supposedly hurt his hamstrings in 2002 before being shut down. I never heard about him complaining of shoulder soreness that year. He was also in his first pro season, at 21, throwing 40 more innings than he had ever before.
