The Dodgers optioned Casparius to Triple-A Oklahoma City on Saturday.
Casparius performed well during his bulk-relief outing Friday, giving up one run and striking out seven batters over 4.1 innings. However, the Dodgers will send him back to the minors in an effort to stack their bullpen with as many fresh arms as possible. Justin Wrobleski will be the choice to take Casparius' place on the active roster.
