Cubs manager Lou Piniella announced his starting rotation on Friday, opting to give the fourth and fifth spots to Tom Gorzelanny and Carlos Silva. Piniella said he's not sure of the order of the rotation after Carlos Zambrano, Ryan Dempster and Randy Wells. Jeff Samardzija and Sean Marshall will go to the bullpen. "The thing I'm happiest about is we sent nobody to the minor leagues," Piniella said. "They went from the rotation to the bullpen. "Remember, when we set this competition up, we didn't know {Angel] Guzman would be out for a whole year and [Jeff] Gray would be hurt."
