The Angels recalled Fermin from Triple-A Salt Lake on Sunday.
The right-hander was unable to earn a place on the Halos' Opening Day roster but will now get a look a month into the season. Fermin had a 4.46 ERA, 1.40 WHIP and 39:23 K:BB across 34.1 big-league innings last year, and he's given up four earned runs with a 16:9 K:BB over 11 frames to begin the season with Salt Lake.
