His ERA was terrible at 5.80 ERA last year, but his xFIP was 3.27, his velocity was still pretty good, he missed bats, limited walks, and is familiar with NL East competition.
I think he would be a better bet than Shaun Marcum and is a low-risk/high reward signing. Bringing him in would be provide solid veteran leadership for our young pitching staff coming up.
Santana, Harvey, Niese, Oswalt, Gee is a pretty solid rotation. Our depth would be strong with guys like Hefner, Wheeler, Gorski possibly available to come up.
