Cardinals' manager Tony La Russa doesn't doubt former slugger Mark McGwire's integrity and would love to have him help St. Louis hitters. "I think if he came to Spring Training and was seen, so the writers and the fans could say, 'There's Mark,' and answer whatever they want," La Russa said, "I think that would go a long way, in my opinion." Ever since McGwire refused to discuss whether he used steroids during questioning at a Congressional hearing in 2005, the former home run champion has made few public appearances.
