A wild first half in Moscow saw the Aggies up by as much as 15, but Utah State eventually settled for a 31-25 lead by halftime Thursday night.
Jarred Shaw led the team with 12 points as the Aggies sprinted out to a quick lead. After trading baskets, Utah State went on a 16-1 run that put them firmly in control at the Cowan Spectrum.
The Vandals responded with an 11-0 run of their own, and closed the gap to only two points. A late surge toward the end of the half was capped by a Marvin Jean 3-pointer that gave the Aggies a six-point edge at the intermission.
