Greg Walker

After nine seasons serving as the hitting coach of the Chicago White Sox, including their victory in the 2005 World Series, it was announced on October 21, 2011 that Walker was hired by the Atlanta Braves to serve as their hitting coach for the 2012 season. Walker filled the role vacated by the firing of Larry Parrish. Walker resigned in September 2014, as the team compiled a .241 batting average, 573 runs, 123 home runs, and 1,369 strikeouts, struggling mightily in the final month of the season. He returned to the Braves as a special assistant of baseball operations in February 2015.

When he began his coaching career, he did so with the White Sox Triple-A club in Charlotte. In 2003, he joined the parent club as hitting coach.

Walker was drafted by the Philadelphia Phillies in 1977. He was selected by the White Sox in the Rule 5 draft in 1979. He was called up to the major leagues in 1982 and spent almost his entire MLB playing career with the White Sox. In 1988 he had a seizure on the field at Comiskey Park during fielding practice. He was released by Chicago early in the 1990 season and subsequently signed with the Baltimore Orioles. Baltimore released him shortly thereafter.
