German was optioned to Triple-A Scranton/Wilkes-Barre on Sunday following the Yankees' 14-3 win over the Orioles.
German pitched 2.2 innings of relief in the win, allowing just two hit and one walk while recording one strikeout. It was the right-hander's job to provide length on a day the Yankees were short-handed, and that's what he did. However, the Yankees will now send him down for a fresher arm in the form of Ben Heller.
