WASHINGTON -- The Phillies will activate right-hander Mike Adams from the disabled list before Sunday's series finale against the Nationals.
They optioned right-hander B.J. Rosenberg following Saturday's 5-3 victory to make room for Adams on the roster.
Adams has been on the disabled list because of a strained back. He threw a bullpen session Friday in Clearwater, Fla., and while he appeared rusty after not pitching since May 10, the club declared the veteran good enough to go.
Adams is 1-3 with a 3.00 ERA in 17 appearances this season.
