MISSOULA, Mont. (AP) — Ahmaad Rorie scored 28 points, Michael Oguine added 15, and Montana used a pair of clutch 3-pointers in the final minutes to stave off Portland State's comeback attempt and defeat the Vikings 82-85 on Saturday night.

Montana (14-14, 9-6 Big Sky) led 62-48 with 7:42 to go, but Portland State used a 14-4 run to cut it to 69-68 on Khari Holloway's 3-pointer with 2:32 remaining. In nearly identical fashion, the Grizzlies made back-to-back left corner 3s set up by drives into the lane — first Walter Wright found Oguine and then Rorie hit Bobby Moorehead to give Montana a 75-68 lead with 1:14 left.

Portland State (12-13, 5-9) got within one on a trio of Deontae North free throws with 2.5 seconds left, but the Vikings' couldn't get a final shot off.

North led the Vikings with 23 points and De'Sean Parsons added 19 points and 13 boards.

Montana is tied with Montana State, which beat Sacramento State 62-59 on Saturday, for fourth in the conference standings.
