Berkman Day to Day with Calf Strain
ST. LOUIS (AP) -- St. Louis Cardinals first baseman Lance Berkman could miss the weekend series against the Chicago Cubs with a left calf strain.
An MRI showed no significant problem for Berkman, who said Thursday that the calf was much improved from a day earlier when it was very sore. He considered himself day to day.
Manager Mike Matheny said Matt Carpenter and Daniel Descalso could fill in at first base while Berkman is out.
The Cardinals play their home opener on Friday against the rival Cubs.
