Cole Kimball to disabled list; Mattheus called up

SAN DIEGO - The Nationals put right-hander Cole Kimball on the disabled list today with right shoulder inflammation, the team announced. In his place, they called up reliever Ryan Mattheus, who had thrown 10 shutout innings so far this season at Triple-A Syracuse.

Mattheus, who was one of two players the Nationals got from the Rockies at the 2009 trade deadline in return for Joe Beimel, will be in the majors for the first time.
