Lagace scored his sixth of the season when he took a long Alex Biega pass and went in alone to beat Jeff Frazee as he was falling to the ice. The multi-point night was the first of Lagace's season and fourth of his two-year career.
Veterans Colin Stuart, Shaone Morrisonn, and Derek Whitmore added single markers for the Amerks, who will next host Hamilton on Saturday.
Lagace: G, A
Biega: A, +1
Schiestel: 1 SOG
