All this talk about Henderson Alvarez and machinations to keep him is just so off focus. As Zambonir said, he was a veteran arm given a tryout (essentially free for the Phillies) that might take some pressure off young pitchers in September by taking a few of their innings. Nothing more.
Pitchers like him do get ST invites all the time. He probably has been good enough to merit one from us. But seriously he would go into Spring Training as something like our 10th starter. He'd be destined for AAA and there is no reason to expect more. He probably won't get any guaranteed offers from anyone so he'll take the team that offers him the best chance of making a roster. At the moment I would submit that is unlikely to be the Phillies for these reasons:
A. We will sign one or more veteran pitchers
B. We have a half dozen young pitchers that will compete for 2-3 rotation spots (Eickhoff, Velasquez, Pivetta, Eflin, Eshelman, Lively, even Letier). All these arms have more of a future than Alvarez.
C. We won't offer him significant money (because we don't have to in order to get pitchers to compete for our rotation spots. We already have enough pitchers as good as him).
D. He is not worth a 40-man spot over the winter.
Alvarez was here as a warm body to take pressure off of the kids. Maybe we'll give him a ST invite. He just isn't good enough or in demand enough to merit anything else. There is nothing wrong with that. He helped us by taking innings. We helped him by giving him a major league showcase. That is all it was/is.
