As a Braves fan who has seen both Soriano and Proctor do some time in Atlanta, I was rather surprised when the Yankees offered such a huge deal to Soriano based on one really awesome year in Tampa. Soriano's always had big time stuff but he could be very volatile; his mental makeup mixed with New York should have sent up a red flag. This signing kind of reminded me of the kneejerk signing of Jaret Wright after a one year resurgence several years back. However, I also expect that at some point after this very rough season for him that he will return to being at the very least a high end setup man, perhaps even for NY if they don't end up moving him.
As for Proctor, he may have been useful years ago but he is finished, his fastball is flat and just begging to be crushed. I guess the Yanks took a flier on him recapturing some of his old magic, I wonder how much they actually saw him pitch this year.
