Milone was designated for assignment by the Mariners on Saturday, Daniel Kramer of MLB.com reports.

EDGE Analysis

Milone was called up to make a spot start against the Rockies on Saturday after Marco Gonzales was placed on the paternity list, and he pitched well while allowing one run over 4.2 innings of work. With Gonzales expected back next week and a full Seattle rotation, there's no room for Milone on the roster. if he goes unclaimed, he will likely report back to Triple-A Tacoma.
