I am not stating whether or not he was good last year. His walk ratedropped a significant amount moving from AAA to the majors and his home run rate dropped more than a significant amount making that same jump. Typically, pitchers do not see gains in their ratios while going from a lower level to a higher level. It's very likely that we see significant regression in both rates, and minimal improvement on his K rate. His FIP will skyrocket in a hurry if that happens. Maybe saying he sucks is a little harsh, but I wouldn't expect an ERA south of 4.50. I'd much rather have Sean Marshall in the rotation over both Gorzy and Wells. I'd try out Guzman there first too, but I can see why some people wouldn't want to risk the higher stress to cause him to get injured again.
