Dodgers manager Dave Roberts said Sunday that Graterol (hamstring) will throw a bullpen session soon, Fabian Ardaya of The Athletic reports.
The right-hander landed on the shelf with a Grade 1 hamstring strain in early August, and he's making a relatively quick return to mound work. Graterol suffered the injury during his season debut after he missed the first four months of the campaign due to a shoulder injury.
