Signed to a minor league deal with the club in March after being released by the Tigers, Pauley joined the Angels bullpen earlier this month when LaTroy Hawkins hit the disabled list with a broken finger.
The 28-year-old Colorado native threw 9 1/3 innings for the Angels this season, racking up just four strikeouts, three walks and a 4.82 ERA in that span.
The "other" player sent to Detroit in the Doug Fister trade last year, Pauley has a 4.54 ERA and 5.3 K/9 in 202 1/3 innings across parts of five major league seasons.
Middle infielder Andrew Romine will get the call-up from Triple-A to take Pauley's spot on the roster, dropping the number of pitchers on the Angels' roster from 13 to 12.
