Hultzen (shoulder) will report to spring training as a reliever, Ryan Divish of the Seattle Times reports.
All 35 of Hultzen's professional appearances to this point have come as a starter, but with the lefty coming off yet another season plagued by shoulder issues, the team has decided to transition him to a full-time relief role. Hultzen, the second overall pick in 2011, was designated for assignment last month, went unclaimed on waivers, and was then outrighted to Triple-A Tacoma.
