"The Major League Baseball Players Association has filed a grievance on behalf of Carlos Zambrano, who was placed on the disqualified list after he cleaned out his locker and left Turner Field following a bad outing for the Cubs.

Zambrano served up five home runs to the Braves last Friday, then threw inside twice to Chipper Jones and was ejected from the game with one out in the fifth inning. He subsequently packed his gear, told team officials he was retiring, and left the ballpark before the game was over.

The Cubs placed Zambrano on the disqualified list on Saturday, which forbids him from being around the team for 30 days. He also will not be paid during that period.

However, the MLBPA has filed a grievance to lessen the penalty. A spokesman for the Players Union said Thursday there is no timetable regarding the grievance process. The two sides will eventually meet, and if no settlement is reached, there will be a hearing in front of an arbitrator. "
