Tony La Russa is retiring after 33 seasons as a manager, and he's going out on top. He told reporters his decision today at a press conference, three days after his Cardinals won the World Series. La Russa captured three World Championships in his career and won Manager of the Year four times. He managed the White Sox, Athletics, and Cardinals in a career that began in 1979. Prior to that, La Russa played six seasons in the Majors as a middle infielder.
