The Dodgers reinstated Grove (ribs) from the 15-day injured list Wednesday.
A right intercostal strain forced Grove onto the injured list in mid-June, and he began a rehab assignment with Triple-A Oklahoma City on July 21. In six appearances in the minors, he allowed two earned runs in 5.1 innings while striking out seven batters and walking two. Now fully recovered, he'll take on a middle-relief role with the Dodgers in place of Brusdar Graterol (hamstring), who landed on the injured list in a corresponding move.
