Tony La Russa is so excited about returning for a 16th season as St. Louis Cardinals manager that he's ready for spring training now. But he's not sure yet whether hitting coach Mark McGwire, a father of five torn by love of baseball and family responsibility, will also be back. The Cardinals hope to get an answer from Big Mac in the next few days or so. http://sports.espn.go.com/mlb/news/story?id=5705214
