Cardinals' first baseman Albert Pujols will miss at least three weeks of action after straining his left calf on Monday, according to The St. Louis Post-Dispatch. "The first indication is that it?s not the scenario that would have kept him out for six weeks to two months," Manager Tony La Russa said. "We?re holding our breath." St. Louis is hopeful that he'll be able to return before the All-Star break. "It?s the second time it?s happened, so we need to get him well," La Russa said. "Going back to last year, it?s the third time. We?ll just try to get it 100 percent healed."
