A White Sox source told the Sun-Times that the team will sign veteran outfielder/first baseman Darin Erstad to a one-year contract with an option, pending a physical. Those talks with Erstad heated up during the last few days after the Sox learned about Podsednik's latest setback. Williams said Podsednik's injury wasn't the same sore left adductor that slowed him last spring but was ''the groin injury he had four years ago in Milwaukee.''
