MLB.com reports Z will begin a throwing program:
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.
Z isn’t expected back before the All-Star break; when Lou has details, we’ll post them here.
