The Dodgers reinstated Graterol (hamstring) from the 15-day injured list Tuesday.
Graterol will return from the injured list a day earlier than originally expected, taking the place of Anthony Banda (hand), who landed on the IL in a corresponding move. The 26-year-old Graterol allowed two earned runs in just one-third of an inning before leaving his season debut with a hamstring strain Aug. 6, so there's a good chance the Dodgers limit him to low-leverage outings until he's able to find his footing in the big leagues.
