Beleaguered manager Don Mattingly insisted Monday he doesn't feel he's about to be fired by the Los Angeles Dodgers, and he has no idea whether he needs to win a three-game series against the Milwaukee Brewers to keep his job. Mattingly's comments came an hour after general manager Ned Colletti said his manager is "doing fine" and has kept the team steady despite its last-place showing in the NL West. Mattingly said he talked with team president Stan Kasten within the past couple of days and didn't get any indication he was about to be replaced.
