A White Sox source confirmed Friday night that vice president/assistant general manager Rick Hahn interviewed Friday for the vacant GM position with the St. Louis Cardinals. Hahn, an assistant GM to Kenny Williams since 2002, talked to two Cardinals officials at the team's spring training complex in Jupiter, Fla. Hahn wasn't present Wednesday night at an Arizona Fall League game attended by 11 Sox officials and scouts, but he was en route to Arizona for the start of the team's organizational meetings that start Saturday in Phoenix.
