MISSOULA, Mont. -- Ahmaad Rorie scored 20 points and Montana clinched the Big Sky Conference regular season title with 75-57 victory over Weber State on Thursday night.

Montana (22-7, 15-2) eliminated both Weber State (19-10, 12-5) and Idaho from contention with a game remaining. It's the Grizzlies' 11th regular-season championship and their first since 2015.

The Wildcats, along with Idaho and Eastern Washington, have a shot at a second-place finish.

Rorie was 7 of 11 from the field and made three of Montana's four 3-pointers. Fabijan Krslovic added 15 points and 11 rebounds for the Grizzlies, who shot 31 of 58 (53 percent) overall. Jamar Akoh had 12 points and Michael Oguine chipped in 11.

Jerrick Harding had 19 points and Brekkott Chapman 14 to lead Weber State.

Montana led 36-29 at halftime. Weber State pulled to 51-40, but back-to-back dunks from Sayeed Pridgett and Oguine gave the Grizzlies a 20-point lead with seven minutes left and they cruised from there.
