CORVALLIS, Ore. (AP) Ethan Thompson scored 15 of his 17 points in the second half and assisted on a dunk by Warith Alatishe with 4.1 seconds left to help Oregon State beat Arizona State 80-79 on Saturday.

Thompson was 6-of-11 shooting and finished with five assists. Sophomore Jarod Lucas, who made his first career start, made 4 of 6 from 3-point range and led Oregon State (6-5, 2-3 Pac-12) with 18 points.

Thompson converted a three-point play to give the Beavers a 64-57 lead with 9:23 left, but Marcus Bagley scored 11 points in a 15-6 run to give ASU a two-point lead with 3:52 remaining. After Remy Martin hit two free throws to make it 76-75, Lucas was fouled by Alonzo Verge Jr. on a 3-point shot and made all three foul shots to put OSU back in front. Bagley hit a 3-pointer with 11 seconds to go but Thompson found Alatishe for the go-ahead dunk.
