Estevez (back) is scheduled to make his Cactus League debut Friday against the Angels, Anne Rogers of MLB.com reports.
Estevez has been slowed in camp by lower-back tightness but has been throwing off a mound without issue for several days and is nearly ready to test himself in a game setting. The 32-year-old is expected to have enough time to get ready for Opening Day and projects to begin the season as the Royals' closer.
