ST. LOUIS (AP) — The best-case scenario for Lance Berkman is that he returns to the St. Louis Cardinals' lineup after the All-Star break. The 36-year-old first baseman is prepared for news on his injured right knee that's not so rosy. General manager John Mozeliak said Monday that Berkman will be sidelined at least six to eight weeks with significant cartilage damage on both sides of the knee, but an MRI did not appear to show ligament damage.
