Jimmy Rollins, as expected, was placed on the 15-day disabled list by the Phillies Wednesday because of the strained right calf he suffered running wind sprints before Monday's home opener.
The Phillies have replaced Rollins on the roster by purchasing the contract of infielder Wilson Valdez from triple-A Lehigh Valley.
The MRI of Rollins' calf Tuesday revealed the shortstop has a strain between a Grade 1 and Grade 2. Rollins is walking around in a protective boot on his left foot. His stint on the D.L. is retroactive to Tuesday, which means he'll be eligible to return April 28 when the team is playing in San Francisco.
Juan Castro will make his second straight start in place of Rollins Wednesday against Washington, but is likely to be moved from first to eight in the batting order with center fielder Shane Victorino moving from seventh to the leadoff spot during Rollins' stint on the D.L. Look for catcher Carlos Ruiz to move up from eighth to seventh in the order.
