In a shocking development, the Cubs are moving Carlos Zambrano to the bullpen. Zambrano had a horrible Opening Day in Atlanta, but has been decent since then. He pitched well enough in a 4-0 loss last night to win--the reason why the Cubs didn't win is pretty obvious from the final score.
Zambrano's arsenal and talent suggest he could be dominating in short stints, but that's the same reason he's been looked to as a starter. His weakness--emotional imbalance--seems to have mitigated since Zambrano said recently that he would stay cool this year. The thing is, it is not too hard to envision close-game bullpen situations bringing that weakness to the forefront again.
One thing is for certain: The Cubs have been killed not only by a lame line-up, but also by an awful bullpen. This move is Lou Piniella's answer.
