Phillies general manager Ruben Amaro indicated Monday that Carlos Zambrano is unlikely to be promoted before July 1, when he can exercise the opt-out clause in his contract. "This last start wasn't as good as the one prior," Amaro said. "He's been inconsistent. We'll see." When asked if Zambrano can get major league hitters out, Amaro replied, "He can, at times. Right now, I don't know if he can do it consistently." Big Z holds a 2.89 ERA with 29 strikeouts over 33 1/3 innings covering six minor league starts, but it sounds like the Phillies have more faith in Jonathan Pettibone at the moment. Zambrano shouldn't have trouble catching on elsewhere if he opts out.
