Bagwell informed general manager Ed Wade of his decision Saturday. The Astros say Bagwell will remain with the organization in a role similar to his previous position as a special assistant to Wade.
Bagwell was named the Astros' hitting coach on July 11, after Sean Berry was fired. Bagwell said he was "unable to commit to a full season of putting in the time that is necessary to be effective in that role."
Bagwell played with Houston for 15 seasons, and set team records for home runs (449) and RBIs (1,529). He was the National League rookie of the year in 1991, the NL's MVP in 1994 and a four-time All-Star. He retired after the 2005 season.
