Tony La Russa Jr. is a professional baseball manager and former player. As a player, La Russa made his major league debut in 1963 and spent parts of five major league seasons with the Kansas City/Oakland Athletics, Atlanta Braves and Chicago Cubs. After a shoulder injury during the 1964–65 off-season, he played much of the remainder of his career in the minor leagues until retiring in 1977.

Following his playing career, he  was named manager of the White Sox in the middle of the 1979 season and guided the White Sox to an AL West division title four seasons later. Despite being fired in the middle of the 1986 season, the Athletics hired him less than three weeks later, and La Russa led the A's to three consecutive AL championships from 1988 to 1990 and the 1989 World Series title. He left Oakland following the 1995 season to manage the Cardinals, and led the team to three NL championships and the 2006 and 2011 World Series titles. La Russa retired after winning the 2011 title and 34 seasons as a major league manager. In 33 years as a manager, La Russa guided his teams to three World Series titles, six league championships, and 12 division titles. His 2,728 wins is third most for a major league manager, trailing only the totals of Connie Mack and John McGraw (as of 2021).

In November 2019, he joined the Los Angeles Angels as a senior advisor of baseball operations. As of 2021, Larussa has returned to the Chicago White Sox as manager.
