ST. PAUL — Mario Lamoureux scored twice during a five-goal third period for North Dakota, and the Fighting Sioux snapped back to stun Minnesota 6-3 Friday in the WCHA semifinals.

Michael Parks and Brock Nelson scored 30 seconds apart to tie the game, and Corban Knight also got a goal to give North Dakota (24-12-3) all it needed for a spot in Saturday’s championship game against Denver. UND has won the last two Broadmoor Trophies.

Defenseman Derek Forbort put the Fighting Sioux on the board after Minnesota (26-13-1) took a 3-0 lead on goals by Kyle Rau, Jake Hansen and Zach Budish. But after Forbort’s slap shot went in with 5:09 left in the second period, the Gophers were outshot 20-3 the rest of the game.
