Mathis Rousseau did everything but score for the Mooseheads on Saturday night, as Halifax was shutout on the road.
The teams played two scoreless periods - including a Phoenix goal that was called back because of a high stick. Rousseau was a big reason why, making some huge stops for Halifax against a talented Sherbrooke squad.
Sherbrooke would eventually strike first, with a shot from Cole Huckins beating Rousseau through the five-hole early in the third period.
The Phoenix extended the lead as a point shot from Marc-Andre Gaudet was deflected in front by Joshua Roy to make it 2-0 on Roy's 33rd of the season.
Amherst, N.S. native Jacob Melanson buried his 42nd of the season into an empty net to wrap up the 3-0 win for Sherbrooke.
The loss was just the second in regulation for the Mooseheads since Nov. 27.
Halifax will wrap up its road trip with a matinee in Quebec City on Sunday. The Remparts host the Mooseheads at 4 p.m., and you can catch all the action on CityNews 95.7.
