PHOENIX -- Cubs manager Lou Piniella said before Monday's game at Chase Field that he expects pitcher Carlos Zambrano to begin working out and throwing this week, but he's not sure when the volatile right-hander will be reactivated.
Piniella also couldn't say when and where Zambrano even will begin working out, only that the team would be putting together a program for him.
"We'll have some details for you tomorrow," Piniella said shortly before the Cubs opened a three-game series against the D-backs.
Zambrano was suspended for three days and has been on the restricted list since a June 25 confrontation with teammate Derrek Lee in the dugout at U.S. Cellular Field when he accused teammates of not playing behind him. Zambrano began evaluation and treatment for anger issues last week in New York with doctors selected by Major League Baseball and the Players Association. When he does return, he will be in the bullpen, not the rotation.
Zambrano, who is in the third year of a five-year contract worth $91.5 million, is 3-6 with a 5.66 ERA in 22 appearances this season, nine of them starts.
