Rollins sent back to Philadelphia for an MRI

NEW YORK -- Jimmy Rollins remained out of the Phillies' lineup Sunday and was sent back to Philadelphia after the team's 3-0 victory for an MRI on his ailing right hamstring.

Asked when he thought he might be able to return from the hamstring injury that forced him to miss the entire series against the New York Mets, Rolllins said he did not know.

Asked  how he felt, four days after suffering the hamstring injury, Rollins said, "the same, unfortunately."

Wilson Valdez made his third straight start at shortstop and the Phillies also added Brian Bocock to the roster, giving them a second shortstop in Rollins' absence. Manager Charlie Manuel did not have that luxury Saturday when he wanted to hit for Valdez with a man on second and one out in the ninth inning during Saturday's 4-3 loss to the Mets. Valdez grounded out for the second out of the inning.

Bocock hit .226 this season for triple-A Lehigh Valley. He also joined the Phillies briefly earlier this season, but he did not appear in any games. To make room on the 40-man roster, the Phillies designated righthanded pitcher Cesar Carrillo for assignment. Carrillo had been claimed off waivers by the Phillies Thursday.
