WATERVILLE – Jayda Murray hit two clutch free throws with two seconds on the clock to seal the win for the Purple Panthers.
Waterville led by as many as nine in the second half, but they went cold from the field and the Black Raiders took advantage.
Winslow took the lead with just over 90 seconds to play in the game after Paige Trask put back a missed shot, 41-40.
The Black Raiders would intentionally foul Murray to get the ball back with two seconds left, not before she hit two free throw to give Waterville the lead 42-41.
Winslow got the ball and attempted a buzzer beater from the opposite three point line, but it was well short.
Waterville stays undefeated, sitting second in the Class B North standings, and face Belfast on Tuesday.
