Ortega was recalled from Triple-A Salt Lake on Wednesday, Sam Blum of The Athletic reports.
Ortega was demoted after giving up five runs (one earned) over two innings during his last appearance for the Angels on June 11, and he'll return to the majors ahead of Wednesday's matchup with the Royals. The 25-year-old has appeared in 20 big-league games this year and has a 3.81 ERA, 1.38 WHIP and 24:12 K:BB over 26 innings.
