Marlowe was recalled from Triple-A Tacoma on Thursday, Ryan Divish of The Seattle Times reports.
It will be the first stint in the big leagues for Marlowe, who has slashed a pedestrian .255/.332/.461 this season with Tacoma but has 11 home runs and 25 stolen bases. The left-handed batter is starting in left field for the Mariners on Thursday and could see a decent amount of playing time there while Jarred Kelenic (foot) is on the shelf. He's someone worth speculating on in deeper formats.
