FORT COLLINS, Colo. -- Pierce Hornung scored 13 points, grabbed 15 rebounds and shut down Drew Gordon in leading Colorado State to a 71-63 upset of New Mexico (No. 21 ESPN/USA Today, No. 18 AP) on Tuesday night.
Hornung also had four steals as the Rams (17-9, 6-5 Mountain West) extended their winning streak to 12 at Moby Arena.
The Lobos (22-5, 8-3) lost for the first time since Jan. 21, ending a spectacular stretch in which they won seven straight games by an average of 19.3 points.
Gordon scored 13 points and had six boards but played nothing like he did last weekend, when he had a career-best 27 points and 20 boards in a 65-45 demolition of then-No. 11 UNLV on national TV that vaulted the Lobos back into the rankings.
