The Nats have been without Drew Storen all season and Adam Kilgore has reported that they will now be without reliever Ryan Mattheus:
Nats announce they placed Ryan Mattheus on the DL and activated Chien-Ming Wang.— Adam Kilgore (@AdamKilgoreWP) May 22, 2012
Mattheus has a partial tear of plantar fascia and is now on the 15-day DL. Mattheus has six holds this season and has a 2.25 ERA in 20 innings to go along with 13 strikeouts.
The Nats will send Wang to the bullpen to provide depth and support to the depleted pen. Brad Lidge is still on the DL and Henry Rodriguez continues to struggles, so the Nats will take any help they can get.
The Nationals went to set-up man Tyler Clippard to finish the game and record his first save on Tuesday night.
