After losing Roy Halladay and John Lannan to injury, Zambrano may have to step in to the rotation in Philadelphia after a few minor league starts. He is a career 132-91 with a 3.66 ERA and a 1.33 WHIP.
Though he may have the credits of being a major league starting pitcher, Zambrano has his issues. He got suspended 4 games for fighting against his own teammate, and has also broken water coolers over a bad start. He is one of those high risk, high reward starters.
If all goes well, Zambrano could be an effective major league starter. If it doesn't, the Phillies may as well just release him. He doesn't cost them that much.
