After more than a week of waiting for right-handed closer Brandon Morrow’s sore right arm to return to 100 percent, the Mariners ran out of patience and opted to put him on the 15-day disabled list.

Because it is retroactive to April 23, the last time he pitched, Morrow is eligible to come on the DL on May 9.

“Brandon’s situation was that he hadn’t pitched in about seven days and there will was some bicep tendinitis in there,” manager Don Wakamatsu said. “We had talked about him being available, but it’s at the point where we will be pro-active with this and allow him seven or eight more days. We can control it a little bit more (if he’s on t he DL). We feel it’s the best move for Brandon and for the club.”

Right-hander Denny Stark was promoted from Triple-A Tacoma to replace Morrow on the 25-man roster. He’ll likely pitch in the fifth to seventh innings. Right-hander David Aardsma would take of the closer role and backed up by Shawn Kelley.

Morrow leads the team in saves with five, while Aardsma has three.
