the venue is not the reason for his slump. the Rockies and Brewers scouted him very well and have given the rest of the league the book on how to pitch to him.
he will not break out of his slump until he make adjustments at the plate or teams start pitching him differently. Hopefully the Cubs didn't read the scouting reports. 
Zambrano is the exact same type of pitcher as Gallardo. sinking fastball and a nasty slider. this team should hit him tomorrow night.
He's hitting the ball hard at times. I think it's just a slump. I hope I'm right.
