Johnson was informed Friday that he has made the Angels' Opening Day roster, Rhett Bollinger of MLB.com reports.
Johnson has been making a strong case to not only make the big-league roster but also be part of the Halos' rotation. While he'll be part of the roster, his exact role remains uncertain. He and Jack Kochanowicz, who will also make the Opening Day roster, had seemingly been competing for the fifth spot in the rotation, and that path could be clear with Alek Manoah struggling this spring and Grayson Rodriguez (elbow) battling injury.
