The Phillies finally placed Jimmy Rollins on the 15-day disabled list with a sprained left ankle.

The move seemed obvious.

In fact, it probably should have been made earlier.

Rollins said he felt his ankle has improved a little every day, but it clearly hasn't improved enough. And at some point the Phillies simply had to allow Rollins' ankle to heal, rather than have him pinch-hit and strain it for no reason. Rollins will be eligible to be activated May 5 in Arizona. Double-A Reading infielder Brad Harman has been promoted to take Rollins' place.

This is the first time Rollins, who injured the ankle April 8, has been on the DL in his eight-year career.

The Phillies also placed outfielder Chris Snelling on the DL with left knee inflammation. They recalled triple-A Lehigh Valley outfielder T.J. Bohn to take his place.

Harman, 22, was hitting .222 (12 for 54) with three doubles, one home run and three RBIs in 16 games for Reading. He hit .281 with 13 home runs and 62 RBI in 122 games last season for single-A Clearwater. Bohn was hitting .190 (8 for 42) with one double in 13 games for Lehigh Valley. Bohn previously played in the major leagues with Seattle in 2006. He was claimed off waivers by the Phillies last September.

Harman will wear #18 and Bohn #12.
