The Dodgers recalled Mills from Triple-A Oklahoma City on Saturday, Maddie Lee of the Los Angeles Times reports.
Mills spent all of July in Triple-A, where he allowed three hits and one walk while striking out seven across 6.2 innings that spanned six outings. The addition of Mills and Kyle Hurt will bolster the Dodgers' bullpen, with Will Klein (elbow) moving to the 15-day injured list and Cole Irvin being designated for assignment in corresponding moves.
