Magill (shoulder) returned to Seattle on a minor-league contract Thursday, Corey Brock of The Athletic reports.

EDGE Analysis

Magill elected free agency rather than accept an outright assignment to the minors in late October, but he'll wind up back in the Mariners' minor-league system nonetheless. The righty recorded a 6.10 ERA and 1.45 WHIP in 10.1 innings this season before being shut down with a shoulder injury which eventually required surgery. He's expected to be ready to go by spring training.
