CINCINNATI (AP) - The St. Louis Cardinals are expected to activate first baseman Lance Berkman off the disabled list before today's game against the Cincinnati Reds. Berkman went through a trouble-free intensified workout yesterday as he recovers from a cartilage tear in his right knee suffered May 19. Manager Mike Matheny says he's going to "have to get creative" in figuring out ways to ease Berkman back into the lineup.
