Sedlock will begin the season at High-A Frederick, Steve Melewski of MASN Sports reports.
Sedlock pitched just one inning for the Orioles this spring, and it was one to forget. He allowed four runs off five his, two of which were home runs. The club is being patient with Sedlock's development, so the prospect's rough spring outing isn't worth getting hung up on moving into the 2017 season.
