Cubs outfielder Milton Bradley pulled himself from the team's lineup an hour before Saturday's game against the Cardinals. Bradley told Chicago's trainer that his left knee was too sore for him to play. For good measure, Bradley added after the game that he hasn't enjoyed his time with the Cubs. "Not really," he told the Chicago Tribune. "It's just not a positive environment. I need a stable, healthy, enjoyable environment. ... It's just negativity." The Cubs are on the hook for the second season of Bradley's three-year, $30 million contract.
