The Blue Devils led 5-2 after five complete innings Friday, but the Lancers scored five runs in the top of the sixth thanks to two errors and a couple walks.
Plum City couldn't push any runs across in the bottom of the inning and they wouldn't get another chance to answer. The game was called in the top of the seventh because of snow at Plum City's Legion Park.
"We played really good baseball for the first five innings," Blue Devils coach Kevin Mueller said.
Tyler Niebur suffered the loss. He struck out six and walked four in six innings of work.
Chad Fox drove in all but one of the Blue Devils' runs. He went 2-for-3 with a home run and a triple.
Plum City (1-3) travels Monday to Mondovi.
