The Nationals' most prized possession, Stephen Strasburg, was on target and up to speed Sunday in his first rehab start since Tommy John surgery, according to an ESPN.com report on Sunday. Twenty-five of 31 pitches were strikes, his fastball was in the upper 90s, and he struck out four while allowing one run over 1 2/3 innings for the Class A Hagerstown Suns in a 7-5 loss to the Greensboro Grasshoppers.
