It won’t happen now, but if Freddy Garcia does get removed from the Seattle rotation, it could be either Julio Mateo or Rafael Soriano who replaces him.
Soriano is the one who projects as a starter for the long term, but since Mateo is more stretched out right now, he could be the choice. AL-only leaguers with an open roster spot should consider picking him up and rooting for another poor outing by Garcia.
