"We certainly need to add a lot of depth over the course of the winter," Cubs general manager Jed Hoyer said Wednesday. "We traded Paul [Maholm] and Ryan [Dempster] and we have to replace those guys going forward."
Maholm was dealt to the Braves, Dempster to the Rangers. Garza (5-7, 3.91 ERA) made 18 starts before he was shut down and has yet to throw since his last start July 21.
"We're certainly hopeful that he's 100 percent but we won't be able to assess that until later on," Hoyer said.
