McCabe scored the game's first goal at 7:18 when he took a Riley Barber pass in the high slot and wired a shot through a maze of bodies past Canadian netminder Malcolm Subban.
A scorer of just five goals through 42 career NCAA games, Captain McCabe gathered his second of the afternoon on a similar play at 16:02 when he again stepped into the slot and beat Subban through a screen to give the Americans the 2-0 lead.
USA stormed out of the gates in the middle frame, getting their third goal of the game just 2:58 in when McCabe cleared a puck out of danger from the USA crease right to the stick of Bosron College standout Johnny Gaudreau, who cruised into the Canadian zone and made a nice toedrag before wristing a shot past Subban to make it 3-0.
Just like the American team as a whole, McCabe has shown tremendous game-over-game growth en route to collecting three goals and six points through USA's six tourney games. His plus-seven rating is tied with Seth Jones ('13) for the team lead. With an emotional win over their continental rival behind them, USA will ride a wave of momentum into Saturday's gold medal game against the winner of Thursday's Russia-Sweden tilt.
