The Rams were coming off two straight losses that knocked them out of the Top 25.
Olekaibe led Fresno State (9-18, 3-11) with 18 points on 6-for-6 shooting from 3-point range. The Rams put Jon Octeus and Daniel Bejarano on Olekaibe to start the second half and held him to just an early 3-pointer.
Marvelle Harris had 14 points for the Bulldogs. Foul trouble limited Tyler Johnson to four points.
Octeus provided momentum with a dunk off a steal, and Green capped the 9-4 mini-run with a layup off a baseline drive to make it a 51-42 game. Allen Huddleston hit a short jumper and had four free throws to get Fresno State within 51-48.
Harris’ 3-pointer cut the margin to 53-51, but Fresno State missed its next six shots as a 10-0 Colorado State run was culminated by a dunk by Octeus with 5:48 left.
Colorado State led 37-34 at the break, but Olekaibe kept the Bulldogs close with 15 points. Olekaibe made his first three shots, all 3-pointers, to pull Fresno State within 20-19 midway through the half.
Huddleston, who finished with 12 points, had a layup off a steal put the Bulldogs ahead 34-32. Bejarano’s 3-pointer and a scoop shot by Eikmeier in the last minute gave the Rams a three-point edge at halftime.
