Greg Maddux, who won four Cy Young Awards and 355 games, will announce his retirement Monday.
Maddux will hold a news conference at baseball's winter meetings in his hometown of Las Vegas, according to a statement from his agent, Scott Boras.
Maddux, 42, closed out his career with the Dodgers. He did not start in the playoffs and made his final appearance in the National League Championship Series, mopping up for Chad Billingsley in the game in which the Philadelphia Phillies eliminated the Dodgers.
Maddux said that day he was not offended by serving as a mop-up man.
"It was a privilege," he said. "I felt privileged to do it. I was glad I had a chance to pitch.
