Carlos Zambrano was impressed by the new Yankee Stadium and thought about what a similar new venue might look like for the Cubs. ?You come into a ballpark like this and you see great things,? Zambrano told the Associated Press on Saturday. ?You wish that Chicago'd build a new stadium for the Cubs." Manager Lou Piniella didn't agree with Zambrano's assessment. ?I don't see why,? Piniella said when asked if the Cubs need a new ballpark. ?Wrigley's got its own uniqueness."
