Jhonathan Diaz reassigned to minor league camp

The Mariners have reassigned Jhonathan Diaz to minor-league camp, per team reports.

Fantasy Impact

Diaz has been stretched out as a starter this spring but was never in the mix for a rotation spot, even with George Kirby (shoulder) set to miss time. Emerson Hancock is likely to fill Kirby’s role to start the season, but Diaz remains a depth option if further injuries arise. He will continue building innings at Triple-A Tacoma while awaiting a potential call-up.
