Zimmermann returned to the big leagues Thursday, just more than a year after having elbow ligament replacement surgery. He last pitched for the Nationals on July 18, 2009, and had the operation on Aug. 19.
A premier prospect before he got hurt, Zimmermann pitched in 10 minor league games this season, going 1-2 with a 1.59 ERA and 31 strikeouts in 39 2-3 innings. The right-hander was recalled from Triple-A Syracuse, where he went 1-0 with a 0.53 ERA in four starts this year.
