Graterol (shoulder) was activated from the 60-day injured list ahead of Monday's game against the Phillies, Fabian Ardaya of The Athletic reports.
Graterol joined the club earlier in the day after finishing up a rehab assignment with Triple-A Oklahoma City, and he'll be available out of the bullpen Monday evening following this latest move. The 25-year-old has yet to appear in a big-league game this season but was excellent a year ago for LA, posting a 1.20 ERA and 0.97 WHIP with a 48:10 K:BB and seven saves in eight chances over 67.1 frames.
