Grove (groin) has joined the Dodgers in St. Louis after throwing a bullpen session in Arizona on Wednesday, Bill Plunkett of The Orange County Register reports.
The 26-year-old might be an option to help fill Dustin May's (forearm) spot in the rotation, which comes around again Monday at Atlanta. That would mean skipping a minor-league rehab assignment. Grove had posted an ugly 8.44 ERA through 16 major-league innings (four starts) with Los Angeles prior to suffering a right groin strain in late April.
