When Cardinals first baseman Lance Berkman stepped back to try and catch a popup in foul territory, he had a setback that might land him on the disabled list.

Berkman felt renewed soreness in his left calf at the same spot as the strain that kept him out of the lineup this past weekend. The switch-hitter was removed from the Cardinals' 11-1 victory against the Cincinnati Reds on Wednesday, but that is only the start of an absence that might be several days or, he suggested, more.

"I think the DL is a possibility for sure," Berkman said, referencing the 15-day disabled list. "I'm not saying they need to throw me on there immediately. But we waited a week, essentially, and it's kind of reared up again. So, it's not insignificant. The bottom line is you want to make sure (the injury) is behind you and it's not something you have to battle it at all."

The club officially classified Berkman as "day to day."
