Jordan Zimmermann rebounded from the only rough outing of his minor-league rehab stint with a dominant performance tonight.
Zimmermann, in the final stages of recovery from Tommy John surgery, tossed 4 2/3 innings of shutout ball for Class AA Harrisburg. Facing the Red Sox's Portland affiliate, he allowed just one hit, walking two and striking out three.
This performance was in stark contrast to Zimmermann's previous start, when he was tagged for seven runs and seven hits in five innings at low-Class A Hagerstown.
Overall, the 24-year-old right-hander has pitched exceptionally well over six minor-league starts -- he's got a 2.38 ERA over 22 2/3 innings, striking out 19 while walking three. He has not allowed an earned run in five of those six starts.
The Nationals continue to target mid-August for Zimmermann's return to the major leagues.
