UNDATED (AP) — The St. Louis Cardinals are set to place first baseman Lance Berkman on the 15-day disabled list with a calf injury. Berkman says he took a bad step going after a popup, aggravating an injury that sidelined him last weekend. Rather than battle through the injury, the club felt it best that Berkman take enough time to recover. The 36-year-old Berkman is batting .348 with two RBIs in seven games.
