Vance, I vehemently disagree. I don't think that Prior is irrelevant and expendable, but if Guzman flat out performs better then I think that he should get the spot. If Prior continues the way that he's going, I think he needs to be put on the 15-day DL and stay behind in extended ST to continue to work on his stuff. After he gets more comfortable and starts stretching it out down there, he should go on a rehab assignment for 2-3 starts split between AA and AAA to make sure he's sharp when he makes his debut. I'd aim for him to return around May 4th when the Cubs open up a 6-game homestand against the Nats and Pirates. I don't think the Cubs are going to play that game this year. I think this could be a pivotal time in Mark Prior's Cubs career. He can be replaced if someone can not only win the fifth spot but show flashes of dominance. Guzman has the ability to do so. It's all hypothetical at this point but if Guzman wins the spot and goes on to win his first few starts leading up to a potential Prior return, I could see it being a very difficult situation... Listening to the off-the-record comments by Lou, it's apparent that Angel Guzman fits his profile of his ideal 5th starter; a young guy who throws well with the ability to get better as the season progresses. Having said that, I'm sure Lou would love to have the old Mark Prior but it doesn't look like he'll be around for awhile (if ever). They may not, but IMO they would be foolish not to. He missed a good portion of last year with shoulder problems and hadn't thrown since August I don't believe. Right now I think as he gets his stamina and strength up, his velocity will improve. It is all a matter of fine tuning his mechanics and finding that consistent arm slot. If he can't do that by the end of ST, I don't want him to still be fooling around with it in Wrigley.
