Rio Grande was the one playing catchup, and the RedStorm completed the comeback.
The Golden Bears led by eight early in the second half, but Rio Grande surged ahead behind its 3-point shooting and went on to beat Tech 68-60.
The game was tied 19-19 toward the end of a low-scoring first half before Tech scored the last six points, including a 3-pointer by Bryce Radford and a three-point play by Darrin Martin with 9.8 to go, resulting in a 25-19 lead at the break.
After Tech scored the first points of the second half, the RedStorm started its surge.
Two 3-pointers by Trent Hundley and another from Shiloah Blevins helped make it a one-point game. The Golden Bears went ahead 32-30 before Rio Grande outscored them 14-5 over the next 4:23 to take a 44-37 lead with 10:20 to play.
The RedStorm (1-5, 14-1) led by as much as 13 with less than a minute to play.
Hundley scored 20 points and Blevins 17 for Rio Grande.
The game did end with an entertaining moment for the Golden Bears (12-13, 7-8).
After Trey Robertson missed the back end of a double bonus free throw with 1.6 on the clock, Andrew Work got the rebound and dished to Brant Smithers, who launched an 80-foot desperation shot and got it to go in.
Work finished with 19 points and seven rebounds. Smithers scored 11 points.
