7/28 Roster move
The Cubs officially activated Ryan Dempster from the disabled list Tuesday and optioned right-handed pitcher Justin Berg to Triple-A Iowa. Berg, called up Saturday, did not get in a game with the big league team but came close Monday night. He was warming up in the bullpen. Dempster had been sidelined because of a broken right big toe, injured in early July.
