The Orioles are set to promote Jason Berken from Triple-A Norfolk to take Tuesday’s starting assignment, a move that will give them three rookies in their starting rotation. Berken will replace Adam Eaton, who was recently released, for an undetermined period of time.
Berken, a former sixth-round draftee, was 2-0 with a 1.05 ERA in his first five starts for Norfolk. The Orioles may also have to replace rookie Koji Uehara, who is suffering from a sore left hamstring, at some point. Baltimore’s two most experienced starters — Jeremy Guthrie and Rich Hill — have combined for a little more than five years of big-league service time.
