FORT COLLINS, Colo. -- Preston Medlin scored 18 points Tuesday night and Utah State dominated Colorado State 71-62.

Spencer Butterfield scored 14, Kyle Davis had 12, Jarred Shaw grabbed 10 rebounds, and the Aggies (15-9, 5-7 Mountain West) never trailed.

Utah State opened with a 10-2 run that included Medlin's 200th career trey, and pulled to a 19-8 lead. Butterfield hit consecutive treys -- for his 100th career 3-pointer -- for a 25-10 Utah State lead, and the Aggies led 29-15 at halftime. Colorado State shot just 17.2 percent in the half.

The Aggies built a 19-point lead after a 7-2 second-half run capped by a three-point play by Jalen Moore. The Rams showed some life when Daniel Bejarano and Jon Octeus each hit a trey, cutting the lead to 12, but the Aggies held them off.

Octeus led Colorado State (14-11, 5-7) with 22, Bejarano had 21, and J.J. Avila 14.
