The Athletics list Morris as their starting pitcher for Friday's contest in Seattle.
Morris will be making his second start for the Athletics, after he was bludgeoned for nine runs over four-plus innings versus the Astros in his major-league debut in June. All four of his appearances with the Athletics since then have been in relief, with the last one coming Saturday, when he yielded one run while throwing 35 pitches in two innings against the Orioles. Morris isn't stretched out enough to handle a full workload, so the Athletics will need several innings from their bullpen Friday.
