Non-tender candidate: Phillip Humber

Phillip Humber shocked the baseball world earlier this year by tossing a perfect game against the Rays. Most people didn't even know who Humber was before he tossed that gem. (I knew who he was because I remember him as a Mets' prospect.) Anyway, besides that perfect game, he has struggled this season. He has had several DL stints and has pitched like crap when on the field. The  Mets drafted him in the first round of the 2004 draft, therefore meaning that he does indeed have a high ceiling. Humber, however, will most likely be non-tendered this winter for the following reasons.

He isn't very good. I know that sounds like a stupid reason, but why would you keep a guy who is probably a number 5 starter at best when you have a young pitcher like Hector Santiago waiting under the wings. Humber walks way to many hitters, and his ERA is very ugly. He also has a 9.4 H/9 ratio, which is not very good.

He doesn't have a track record. There is a reason why he has bounced around from team to team throughout his entire MLB career. He didn't even put up good numbers in the minor leagues, which is somewhat alarming.

Overall, Humber will probably not ask for that much through arbitration ($700-$900k.) But think about it, that $700-$900k could be used to bring a proven pitcher to Chicago, not an over-hyped a bust like Humber.
