The deciding factor was wins and losses, and the Cubs didn't win enough under Jim Hendry, who was dismissed on Friday as the general manager after 17 years with the organization.
Cubs chairman Tom Ricketts said the search for a new general manager would begin immediately. Randy Bush, 52, who has been the assistant GM for five seasons, took over on an interim basis, but will not be considered for the job. Ricketts said he wanted to hire someone from outside of the Cubs' organization.
"We didn't win enough games," Hendry said at a news conference at Wrigley Field before the Cubs faced the Cardinals. "You don't win enough games, you can't fight change."
