LOS ANGELES — The week couldn't end fast enough for USC. When it did, the result was a hard-fought victory.

Aaron Fuller's only basket, a layup with 4.8 seconds remaining, gave USC a 69-68 victory over Oregon State on Saturday night.

The lead changed hands eight times in the final 2:52. Eric Moreland fed Joe Burton for a layup with 12.6 seconds to play to give Oregon State (10-8, 0-4 Pac-12) a 68-67 lead.

Devon Collier's game-winning attempt was blocked by Eric Wise as time ran out.

Byron Wesley scored 12 of his 19 points in the first half, and Wise added 18 points for the Trojans (8-11, 3-3). J.T. Terrell, who passed to Fuller for the game winner, scored 11 points.

Roberto Nelson scored a season-high tying 26 points for the Beavers, who overcame a 15-point second-half deficit to take a 49-48 lead with 11:52 remaining. Burton and Collier scored 16 points apiece.

The win was the first of the most recent interim stint for Trojans coach Bob Cantu, elevated after the school fired Kevin O'Neill on Monday. Cantu, who has been in the program 12 years, previously served as interim coach in 2011, in a loss to Arizona.

The Trojans had chances to win but lost by two against Oregon on Thursday. They had to turn around and prepare for a Beavers squad that has driven USC nuts in recent games with a 1-3-1 zone defense.

USC committed 20 turnovers Saturday.

"Man, that 1-3-1 is annoying," Trojans guard Jio Fortan said after scoring just eight points on 2 of 2 shooting. Against Oregon, Fortan had 33 points but missed three crucial shots late.

"This week's dragged out," Fortan said. "We missed a game we should've had and got it done today in a game that should've been easier."

The game was close until late in the first half, when six different USC players scored on the way to a half-closing 15-7 run and 39-31 halftime lead.

USC opened the second half by scoring seven straight points for a 15-point lead that led to an Oregon State timeout. The Beavers answered by outscoring USC 16-2 over the next 6:20 for a 49-48 lead.

"We just stayed with it (1-3-1 zone) because it was working so well," Beavers coach Craig Robinson said. "We forced some great turnovers and got some great results.

"But we can't enjoy it much because it is such a bitter loss."

The Trojans didn't score for 5:40.

"When a 15-point lead starts to evaporate, my blood pressure certainly goes up," Cantu said. "The guys didn't give up. They fought. We turned it over too much, but we found a way to get the win."

Moreland and Victor Robbins returned to the Oregon State lineup after missing three games for violating team rules. Moreland had three points, eight rebounds, the late assist and three turnovers, one of which led to a late USC go-ahead score. Robbins played one minute.

Neither team led by more than four points in the final five minutes. Collier's offensive rebound on his own miss gave OSU a 62-61 lead with 2:26 to play.

Wise put USC back on top with two free throws with 2:02 left, and the Beavers responded with Collier finding Burton down low for a layup and a 64-63 lead.

Wesley dribbled through traffic and scored a layup with 1:14 to go, and Nelson answered with a jumper to put the Beavers back on top with 45 seconds remaining.

Wise stole an inbound pass that Moreland couldn't handle and scored for a 67-66 lead with 26 seconds left.

Utah 74, Washington 65

At Seattle, Jason Washburn scored 14 of his 18 points in the first half, Brandon Taylor added a career-high 19 off the bench and Utah won its first Pac-12 road game in two seasons as a member of the conference with a stunning win over Washington.

The Utes (9-9, 1-5 Pac-12) were winless in conference play this season and having last won a Pac-12 game on Feb. 25, 2012 against Stanford, used hot shooting and a smart defensive plan to take down the Huskies and hand Washington its first conference loss. Washington was trying to start 5-0 in conference play for the first time since 1984. Instead the Huskies (12-6, 4-1) were left shaking their heads at their execution in the closing minutes that ruined what Washington accomplished winning its first three conference games on the road.

No. 7 Arizona 71, Arizona St. 54

At Tempe, Ariz., Mark Lyons scored 24 points, Nick Johnson added 19 and Arizona pulled away in the second half after Jahii Carson picked up his fourth foul to beat the Sun Devils.

Arizona (16-1, 4-1 Pac-12) was solid at both ends, hitting 14 of 25 shots in the second half and stymieing the Sun Devils at the defensive end all game.

The Wildcats forced Arizona State into 17 turnovers — leading to 18 points — and freshman Brandon Ashley had the best defensive game of his young career, helping to hold Carrick Felix, Arizona State's second-leading scorer, to five points on 1-of-8 shooting.

Arizona also managed to get Carson in foul trouble, picking up a charging call against him just before halftime and another foul on a hard drive by Lyons midway through the second. The Wildcats capitalized with Carson out, using a 9-0 run to build an 11-point lead that was never really challenged.

Stanford 69, California 59

At Stanford, Calif., Dwight Powell scored 17 points and Chasson Randle added 15 in helping Stanford beat California.

John Gage added 14 points for the Cardinal (11-7, 2-3 Pac-12), who had lost three of their previous four. Josh Huestis had 12 rebounds to go with nine points.

Allen Crabbe and David Kravish each scored 14 points to lead the Bears (10-7, 2-3 Pac-12), who have lost four of their last six. Justin Cobbs added 13 points.

California drew within 43-42 with 13:20 left to play on a Crabbe jumper but the Cardinal eventually rebuilt its lead to 10 points.

Gage hit one of his three 3-pointers with 7:07 remaining to play in the first half to put the Cardinal ahead.

Crabbe, the Pac-12's leading scorer, was limited to four shots in the first half.

Colorado 58,Washington State 49

At Pullman, Wash., Spencer Dinwiddie scored 16 points and had eight rebounds as Colorado came up with a great defensive performance to beat Washington State.

Two freshmen contributed with double figures for the night as Xavier Johnson added 14 points and Josh Scott chipped in 11 as Colorado (12-6, 2-4 Pac-12) rebounded from a loss Wednesday night against Washington.

Colorado led 23-19 at halftime. The Cougars erased the deficit by going on a 12-4 run to start the second half, taking a 31-27 lead near the 15-minute mark. The teams traded baskets until 6:08 when Dinwiddie hit Colorado's only three of the night to take a 47-42 lead. Colorado would then go on a run to put the game out of reach at 54-46 with under a minute to play.

Brock Motum and Mike Ladd had 13 points apiece for Washington State (10-8, 1-4). Motum also had seven rebounds.
