Dorian Green scored 14 of his 16 points in the second half, leading Colorado State back from a 16-point deficit to upset No. 17 UNLV 66-59 on Wednesday night.
The Rams (18-10, 7-6 Mountain West) capped a perfect home mark in league play with their 13th straight win at Moby Arena.
They trailed 41-26 at halftime and by 16 points in the opening minutes of the second half before rallying to burnish their NCAA credentials with their third straight home win over a ranked team.
The Rebels (24-7, 8-5) fell a game behind New Mexico and San Diego State in the Mountain West standings. They got 17 points from Oscar Bellfield, but he had just one basket in the second half, a 3-pointer that put UNLV ahead 47-31.
From that point, the Rams outscored the Rebels 35-12.
