The Dodgers recalled Casparius from Triple-A Oklahoma City on Thursday.
Just two days after being optioned to the minors, Casparius will return to the Dodgers' bullpen to make up for the loss of Brusdar Graterol (shoulder), who landed on the 15-day IL on Thursday. The 25-year-old Casparius has been solid during his brief time in the majors, allowing just one earned run over four innings, and he figures to work in middle relief during the final four games of the regular season.
