WASHINGTON -- The Nationals activated Tanner Roark on Friday afternoon, a few hours before his seventh start of the season against Atlanta.
Roark was optioned to Class A Potomac on Aug. 25 with plans for the right-hander to make two starts and stretch out to a starter's pitch count. Questions about Stephen Strasburg's health arose, however, and Roark's second start of the rehab stint on Aug. 31 was limited to two innings so he would be fresh to take Strasburg's spot on Friday.
