Idaho State (11-13, 3-9 Big Sky) had the upper hand throughout the first half, shooting 50 percent from the field, including 6 of 10 from 3-point range. The Bengals used a late 7-0 run to take a 42-33 lead at the half.

Portland State (9-15, 2-9) stayed in the game thanks largely to the shooting of Schroeder, who connected on three first-half 3-pointers.

The Vikings fought back in the second half behind the efforts of junior center Anthony Washington, who scored 11 points in the half, and junior forward Juma Kamara, who hit three second-half 3-pointers.

Kamara gave the Vikings their first lead since early in the game on a 3-pointer with 2:35 remaining that made it 72-70. From there, two driving layups by guard Ryan Sommer capped the victory, the second making it 76-71 with 1:19 left.

Slim Millien led Idaho State with 19 points on 7 for 13 shooting, and David Schroeder added 16 points and eight rebounds in the loss.

Portland State snapped a six-game losing streak.
