Desmond Cambridge Jr. scored 21 points for the second straight game as Arizona State improved to 6-1 in Pac-12 play with a 74-69 win over Oregon State on the road Saturday.

It was a come-from-behind win for the Sun Devils (15-3), who now have their best start to conference play since the 1980-81 season. Arizona State trailed by four points early in the second half before the Cambridge brothers keyed a 9-3 run that flipped the game.

The win extended ASU’s streak of victories to four games, and it secured the first road sweep in Oregon since 2009-10.

The Sun Devils got off to a horrid start in Corvallis just two nights after blasting Oregon. The Beavers opened up a 16-point lead in the game’s first 15 minutes as ASU missed 13 of its first 17 shots.

But then the ASU offense caught fire and knocked down seven straight jumpers to turn in a 13-2 run.

The Sun Devils closed the first half with a 21-8 advantage over the final 5:07 and entered the locker room within just three points of Oregon State.

Cambridge provided a pair of triples and closed out the first half with 11 points to lead the team. ASU hit six of its 12 triples in the first half.

The Sun Devils took a lead for good with 13:07 to play in the second half on a pair of Austin Nunez free throws. ASU pushed its lead to as large as nine in the second half and never looked back.

Cambridge finished with 21 points on 8-of-14 shooting and 4-of-7 from 3-point range. He also had two blocked shots. Devan Cambridge added 13 points and eight rebounds on 5-of-8 shooting. Frankie Collins had 12 points.

The Sun Devils return home for a contest between the Pac-12’s top two teams next Thursday. The UCLA Bruins (15-2, 6-0 Pac-12) come to town for a 7:30 p.m. PT tip on FS1.
