Griffin (elbow) did some flat-ground throwing from out to 90 feet Wednesday at about 75 percent intensity, Colin Beazley of the Pittsburgh Post-Gazette reports.
Griffin threw for the first time since he landed on the 10-day injured list May 31 due to a flexor strain in his right elbow. He also took part in fielding drills without throwing, which is something the rookie has done since first going on the IL. Griffin remains without a timeline to rejoin the Pirates' active roster, but more clarity on that front should become available as he continues to ramp up his throwing.
