Cardinals manager Tony La Russa refused to comment Friday on speculation that he may be a candidate to replace Lou Piniella, who is retiring as manager of the Cubs at the end of the season. "[I just] ignore it," La Russa said. "Ignore it." La Russa did open up slightly when asked about the pressures associated with managing the Cubs. "I wouldn't even answer that question because I don't believe what you're asking is true," La Russa said. "There's nothing about Chicago that's harder than St. Louis. "You got a job in the big leagues, there are 30 of them. They're all demanding and there isn't one that's tougher than the other."
