St. Louis Cardinals outfielder Roger Cedeno was placed on the 15-day disabled list with a minor hamstring strain on Monday.

"He's very unhappy, which is understandable," La Russa said. "But you can't have a four-man bench."

The Cardinals called up outfielder Skip Schumaker from Triple-A Memphis to fill in for the 'injured' Cedeno.
