Radford shot a blistering 68.6 percent from the field in the first half, including 9-of-15 from 3-point range, as it carried a 57-45 lead into intermission. Oregon State was also hot from the floor in the opening stanza (.588) but simply couldn't keep pace.
The Beavers gradually chipped away at their deficit in the second half and trailed by just two, 94-92, with 10 seconds left following a Nelson layup. After Davis had a 1-of-2 trip to the line for Radford, Oregon State had a chance to tie on a Nelson 3-point attempt but it was off the mark. Green nailed a free throw on the other end to put the game out of reach.
The difference came from beyond the arc, where Radford shot 13-of-24, compared to only 6-of-16 for Oregon State.
