The Angels recalled Aldegheri from Triple-A Salt Lake on Monday.
Monday marks the second time this season that Aldegheri has been called up to the majors. His lone outing with the Angels this season came against the Yankees on April 16, when he allowed one earned run on two hits and one walk while striking out two across 1.2 innings. He'll replace Nick Sandlin on the 26-man active roster, the latter of whom was optioned to Salt Lake in a corresponding move.
