Duffy (forearm) completed a bullpen session Sunday and is expected to throw another in the near future, Fabian Ardaya of The Athletic reports.

EDGE Analysis

Manager Dave Roberts indicated less than a week ago that the left-hander was a couple weeks away from throwing off a mound, but that was proven incorrect by Sunday's bullpen session. Duffy could progress to participating in a simulated game if the next bullpen session goes well.
