The victory was the first for the Grizzlies over the Bruins in the five-game history between the two teams.
UCLA (3-4) was hopeful that returning home would help stop a losing streak, but instead lost its fourth in a row. The Bruins were coming off a confidence-building, one-point loss at No. 4 Kansas but weren't able to find their groove against the Grizzlies.
Montana (4-3) held the Bruins to 28 points in the first half by cutting off the inside pass and using a collapsing defense when UCLA was able to get the ball into the paint.
