Ranger scored Toronto's second of three power play goals in the game at 1:31 of the second, then Blacker scored off his own rebound at 2:27.
The scoring spree ended on a power play at 7:24 when Abbott scored his second of the afternoon by finishing off a nice passing play with Ranger and Hamilton.

Syracuse went ahead again at 14:48 when Brown quickly headed to the net after a faceoff in the Toronto zone and scored from close range.
Despite being outshot 22-5 in the first period, Toronto found a second game-tying goal at 15:24 when Abbott scored his first by firing in a one-time shot from a Gardiner pass from the edge of the right faceoff circle.
Toronto had more penalties (six) in the first period than shots.
