Marlowe entered Sunday's loss to the Phillies as a defensive replacement in right field in the ninth inning and went 1-for-1.
The rookie led off the home half of the ninth for the Mariners and delivered his first hit since July 23, the initial game of his current big-league tenure. Marlowe received his promotion from Triple-A Tacoma following the placement of Julio Rodriguez (ankle) and J.P. Crawford (finger) on the injured list, but he's logged only eight plate appearances across seven games since arriving in Seattle.
