At Winslow, ninth-seeded John Bapst took a 2-0 first-half lead on goals by Casey McGuire and Abby Pyne, and Sierra Pierce added two more in the second half in the victory over No. 8 Winslow.
Pyne also recorded the shutout in goal for the Crusaders of Bangor.
“I was very impressed with every single girl’s performance from Abby in goal to Sierra Pierce’s two goals,” said John Bapst assistant coach Josh Jones.
The Crusaders will travel to Presque Isle on Tuesday to take on the No. 1 Wildcats in an EM Class B quarterfinal.
