LAS VEGAS — La'Shard Anderson and Ryan Watkins scored 16 points each, and Boise State dominated the second half to rout New Mexico State 81-63 Friday night and reach the Western Athletic Conference championship game.

Second-seeded Boise State (20-11) used its defense to create scoring opportunities in the first half, then hit a slew of 3-pointers in succession in the second to run away from the defending tournament champions.

Playing with their highest seeding since joining the WAC in 2001-02, the Broncos ran their winning streak to eight games — longest since 1991-92 — and earned a trip to their third title game, against No. 23 Utah State on Saturday.

New Mexico State (16-17) kept within reach despite a rash of turnovers in the first half, but had nothing left in the second half to keep up with the WAC's highest-scoring team. Tyrone Watson led the Aggies with 15 points.
