King will be a member of the Yankees' Opening Day roster, Brendan Kuty of The Newark Star-Ledger reports.
King is expected to begin in a bullpen role, but he could be one of the top options to slide into the rotation when a spot starter is needed. He hasn't shown much to suggest he'll be an interesting fantasy option should that happen, however, struggling to a 7.22 ERA in 28.2 innings at the major-league level.
