According to Ruben Amaro Jr., Carlos Zambrano is not ready to pitch for the Phillies just yet.
Not based on what I saw his last outing, not in my mind. I’d like to see him pitch again in the minors. We’ll keep a close eye on his starts and how effective he is. But he’s not ready yet in my mind. Right now he’s just getting his rhythm back. He hasn’t even had what amounts to a full spring training yet. It all depends on how he pitches. If we think he can help us, we’ll bring him. Right now he’s (Jonathan Pettibone) our starter. We’ve made no change in our rotation. As far as I know, he’ll take his turn on Friday.
The Phillies signed Zambrano in May and has made four official minor-league starts so far. In 21 1/3 innings, he has allowed 14 hits, three earned runs, 11 walks and 17 strike-outs. In his major league career, Zambrano is 132-91 with a 3.66 ERA. If he is not in the major leagues by July 1st, he is able to opt out of his Phillies minor-league contract.
