With Levittown and East Williston tied at 3 early in the third period, Levittown's resilience finally paid off.
The Ice Falcons had already come from behind twice Saturday, when Taylor Trenkle found himself in prime position to give Levittown its first lead.
Trenkle crept into the slot unguarded and received a pass from Joe Finneran, who had drawn the defense deep in the zone along the boards. Trenkle walked in untouched toward the crease and fired a writ shot into the back of the net, giving Levittown a 4-3 advantage it would not relinquish.
Neither team scored the rest of the way as Levittown (8-4-1, 17 points) edged closer to East Williston (9-4-2, 20 points) in the Liberty Division standings.
"The kids played great," Levittown assistant coach Dave Gallart said. "We were down, we stopped the bleeding, took the momentum and started shooting and scoring."
East Williston led 2-0 after the first period, scoring two power-play goals after killing off an extended 5-on-3 Levittown power play.
Finneran scored two tying goals for Levittown, the first to tie it at 2 in the second period and then to knot it at 3 in the third period.
