Mariners' Gabe Speier: Placed on 15-day IL

Speier was placed on the 15-day injured list with a left rotator cuff strain Saturday, retroactive to May 30, Daniel Kramer of MLB.com reports.

Speier last appeared in a game May 29, allowing one hit while striking out a batter over two-thirds of an inning against the Astros. Considering it's his throwing shoulder, Speier may be forced to miss extended time. In a corresponding move, the Mariners called up right-hander Collin Snider from Triple-A Tacoma on Saturday.
