Peralta was called up from Triple-A Salt Lake on Saturday.
Peralta will return to the major-league bullpen following a demotion Monday, replacing Luis Garcia (oblique) after he was placed on the 15-day injured list Saturday. Peralta owns an inflated 8.38 ERA and 2.07 WHIP with seven strikeouts over 9.2 innings in four appearances with the Angels in September.
