The MLB Players Association has filed a grievance on behalf of Carlos Zambrano, according to MLB.com's Carrie Muskat. The Cubs placed the right-hander on the disqualified list Saturday after he struggled against the Braves, cleared out his locker and said he was retiring.
Players don't get paid on the disqualified list, so Zambrano would stand to lose about $3MM if the Cubs' decision holds up. The MLBPA aims to lighten the penalty, though there's no timetable for the process at this point, according to Muskat. The Cubs and the union will meet and, if they don't reach an agreement, they'll go in front of an arbitrator.
Players don't get paid or pick up service time on the disqualified list, so Zambrano could lose as much as one sixth of his $17.875MM salary. He is under contract for $18MM next year and his contract includes a $19.25MM vesting player option for 2013.
