The Phillies placed righthanded reliever David Herndon on the 15-day disabled list with inflammation in his throwing elbow, the team announced after Mondays 6-4 win over the Chicago Cubs (see game story).

A corresponding roster move is set to be made Tuesday.

One potential option might be lefty Jake Diekman, who impressed in spring training and has a 0.82 ERA with 17 strikeouts in 11 innings for Triple A Lehigh Valley.

Herndon has made five appearances out of the bullpen this season, all in Phillies losses, four in games decided by four or more runs.

He has allowed four runs on 10 hits over 7 23 innings, walking one and striking out eight. His value derived primarily from a groundball-inducing sinker, 13 of Herndons 24 balls in play this season have been on the ground.

Herndon becomes the eighth Phillie to hit the DL in the seasons opening month and the fourth reliever.

Michael Stutes is currently shut down with a shoulder injury, Jose Contreras missed the teams first eight games recovering from elbow surgery and Justin De Fratus remains sidelined with an elbow strain.
