The Mariners have designated lefty Edgar Olmos for assignment, the team announced. His roster spot goes to utilityman Rickie Weeks, whose signing was made official.
Olmos, 24, was claimed off waivers by Seattle from the Marlins earlier in the offseason. His miniscule MLB sample does not tell us much, but does indicate that he has a 95+mph fastball. He has struggled to limit the free passes, though is coming off his lowest-ever walk rate over a full season (3.5 per nine in 77 2/3 innings in the upper minors last year).
