Left-hander Danny Hultzen, who was designated for assignment on Friday by the Mariners after three injury plagued seasons, has cleared waivers and will be outrighted to Triple-A Tacoma.
Hultzen thus remains with the Mariners organization that selected him with the second pick in the 2011 Draft and will continue his attempt to work his way back from rotator cuff and labrum surgery that sidelined him for all of 2014 and allowed him to pitch just eight innings last season with Double-A Jackson (0-1, 3.38 ERA) before being shut down again.
Hultzen was moved off the 40-man roster when infielder/outfielder Patrick Kivlehan and outfielder Boog Powell were promoted on Friday to protect them from Rule 5 Draft exposure.
