Andriese (hamstring) tossed a scoreless sixth inning Sunday in his first rehab appearance for Triple-A Worcester, scattering two hits while striking out one.
Andriese is expected to remain with Worcester and make at least one or two more rehab appearances before being activated from the 10-day injured list. Before being shut down with the hamstring issue in early July, Andriese compiled a 6.03 ERA and 1.77 WHIP across 37.1 innings out of the Boston bullpen this season.
