Balderson pitched in the minor leagues for 8 years (1968-1975), all in the Kansas City Royals organization, reaching AA. His career record was 32-21.
He served as General Manager of the Seattle Mariners from 1986 to 1988. It was then that the team drafted Ken Griffey, Jr. Just days after making one of the best trades in team history, acquiring Jay Buhner from the New York Yankees, Balderson was fired from his post as GM.
Balderson was then the scouting director of the Chicago Cubs in 1989-1990 and director of player development in 1991-1992. He moved to the Colorado Rockies as director of player development from 1993 to 1997 and held the same post with the Atlanta Braves from 2000 to 2002. In 2008, Balderson was a Special Assistant to GM for the Braves. He retired in 2013.
