The Tigers selected Hurter's contract from Triple-A Toledo on Sunday.
Alex Faedo will draw the start for the Tigers in Sunday's series finale versus the Royals, but he's likely to work only an inning or two before giving way to Hurter, who is expected to operate as a bulk reliever. A 25-year-old lefty, Hurter will be making his MLB debut Sunday after logging a 5.80 ERA and 1.48 WHIP across 71.2 innings over 19 appearances (18 starts) for Toledo. With the Detroit rotation having been decimated by injuries in addition to Jack Flaherty being sent to the Dodgers at the trade deadline, Hurter should have the opportunity to make additional starts or bulk-relief appearances if he shows well in his debut Sunday.
