Black Hills dropped a league contest on the road on Tuesday, falling 12-2 in five in Aberdeen.
After the Bobcats got on the board in the second, the Wolves responded with an RBI single from Lincoln Brannin to tie the game at one in the top of the third.
Aberdeen scored six runs in the bottom of the third to take control, though, and a five-spot in the fifth was enough for the walk-off run-rule win.
Black Hills’ only other run came in the fifth on an Aberdeen error.
Brannin’s hit stood as the Wolves’ only knock of the game, and he reached base a second time with a walk. Three other Wolves also drew walks in the loss.
Black Hills (3-11, 1-9 C2BL) will face Aberdeen again on Wednesday at home.
