Yabeserra Rich scored three goals, Quincy Thibault added a goal and an assist, and the Golden Trojans (4-1) shut out the Tigers (1-4) in Saco.
Rich’s first goal came in the seventh minute when she collected a deflected cross from Hadley Stoddard and sent a shot from the left side that went off a defender and into the net.
Stoddard intercepted a goal kick, dribbled past two defenders and shot through the legs of Biddeford goalie Sarah Parks at 11:39.
Rich made it 3-0 late in the first half with a left-footed chip from 20 yards after a long pass from Thibault, then completed the hat trick from a nearly identical spot with a similar shot early in the second half.
Thibault completed the scoring on a 30-yard floater that dipped under the crossbar with six minutes left.
Sarah Parks had 21 saves for Biddeford.
