Let's not pretend Petrick is the savior of the Cubs. Up until two days ago, the highest level he had ever pitched at was AA. He has shown flashes of great pitching, but also rough spots (2 run homer in his first appearance). He has only pitched 3.2 innings in the big leagues. He is not a savior, he isn't being punished for his performance, he is a just a guy who came up and did his part, and is going back down to the minors for some more seasoning. Did anybody here really expect a guy whose record includes nothing higher than a bit of AA experience to stick around for the rest of the season? When Petrick is a little more experienced and ready for a full time spot, he'll be back. Until then, I won't shed any tears for him.
