Dorian Green hit two free throws with 9.6 seconds left and scored 18 points to help Colorado State edge Montana 62-61 Saturday night.
Green, who was 5 for 9 from the free-throw line, was fouled on a driving layup and calmly converted the free throws.
Montana (6-4) had two chances to win it, but Anthony Johnson's shot hit the side of the backboard and Derek Selvig missed a tip-in at the buzzer.
Adam Nigon had a career-high 17 points, and Travis Franklin added 11 for the Rams(7-3), winners of five of six.
Johnson led Montana with 19 points. Selvig and Jack McGillis had 10 each.
