The St. Louis Cardinals interviewed Cubs Hall of Fame second baseman Ryne Sandberg and longtime third base coach Jose Oquendo for their open managerial position on Wednesday.  Both interviews took place in St. Louis.  The Cards have interviewed a total of six candidates as possible replacements for Tony La Russa, who retired after winning the World Series last month.  On Tuesday, St. Louis interviewed former Red Sox skipper Terry Francona in Cincinnati, where Cardinals chairman Bill DeWitt Jr. lives.  Joe McEwing, Mike Matheny and Chris Maloney interviewed for the job last week.
