The Angels optioned Crouse to Triple-A Salt Lake on Monday.
One day after being recalled from Triple-A, Crouse will head back to Salt Lake to make room in the bullpen for a fresher arm in lefty Jose Suarez, who was called up from the minors in a corresponding move. Crouse tossed 27 pitches and retired four hitters in his relief appearance in Sunday's 7-4 loss to the Rangers, allowing no runs on zero hits and two walks while striking out one.
