The Mariners announced their Opening Day roster, with a few moves of note. Shortstop J.P. Crawford will start the season on the 10-day injured list, retroactive to March 22nd, due to right shoulder inflammation. Seattle also selected the contract of catcher Mitch Garver, a move that was previously reported. Fellow catcher Andrew Knizner cleared waivers and elected free agency, which opened a 40-man spot for Garver.

More to come.
