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. Ok, I see your point. However, the difference in BB/9 (3.0 in past 3 years at AAA to 2.5 in 2009) amounts to 9 fewer walks over the course of 694 batters faced. The dip in HR/9 (~1.0 to 0.8) amounts to 4 fewer HRs over the innings pitched in 2009. Neither of these changes in rate look like red flags to me. The fact that he was ~50 Ks short of his AAA K/9 is a little alarming, but he otherwise appears to have made the transition to MLB more or less at his AAA rates. While impressive, it's not unheard of, and I don't see why it augurs poorly for him.
