CHICAGO -- The Cubs designated pitchers Justin Berg and Brian Schlitter for assignment on Thursday, and pitcher Carlos Zambrano was added to the 40-man roster.
Zambrano was taken off the 40-man roster when the Cubs determined that he would not be with the team for the final month. On Sept. 2, the Cubs announced Zambrano would not return after his 30-day suspension ended, but that they would resume paying his salary. The suspension ran through Sept. 11.
The right-hander was taken off the 40-man roster at that time so the Cubs would not be limited in the number of players they had available.
Zambrano was suspended after his early exit from Turner Field on Aug. 12. In that game against the Braves, he gave up five home runs, then was ejected because umpire Tim Timmons felt Zambrano was trying to hit Chipper Jones. Zambrano packed his gear and left the ballpark, telling teammates he was retiring.
The Cubs placed Zambrano on the disqualified list on Aug. 13. He finished 9-7 with a 4.82 ERA in 24 starts.
The Major League Baseball Players Association filed a grievance on Zambrano's behalf, which is still unresolved. Major League Baseball, the Players Association and the Cubs will process the grievance this offseason.
Schlitter was first activated from the 60-day disabled list before he was designated. He missed the 2011 season because of a right elbow injury. Berg underwent Tommy John surgery on his right elbow in late September.
