Guilbeau (shoulder) cleared waivers and was outrighted to Triple-A Reno, Nick Piecoro of the Arizona Republic reports.

EDGE Analysis

Guilbeau will be a non-roster invitee to major-league camp. He pitched for the Mariners in 2019 and 2020, inducing a 58.2 percent groundball rate over 20 innings, but he saw his strikeout rate drop moving up to the majors and experienced a drop in velocity due to a shoulder injury.
