In my opinion, Zambrano pitches with more "momentum" then any other pitcher I've seen. He seems to go through slumps much like a batter that is playing everyday. It could be his demeanor where when he's good he thinks he is unhittable and when he's bad he is really hard on himself. I'm hoping its just mechanics, maybe his arm slot, and that he will get confidence and pitching well shortly. He's desperately needed if we make it to the playoffs.
