Jeff Bagwell, the face of Houston baseball for a generation with teammate Craig Biggio, will retire Friday after 15 years with the team. The four-time All Star will remain with the Astros as part of a personal-services agreement reached with the team earlier this week, according to a person familiar with the team's plan who requested anonymity because an official announcement had not been made. Bagwell is expected to work with young Astros hitters, assisting in the front office and making appearances for the team. The Astros have scheduled a Friday morning news conference to announce the retirement. Bagwell, 38, leaves the Astros as the team's all-time leader in home runs (449), RBIs (1,529), walks (1,401) and extra-base hits (969). He had a lifetime batting average of .297.
