EUGENE, Ore. (AP) When Oregon State threatened to turn the Civil War into a battle again, Oregon's hottest hand loaded up one more time.
As the shot clock ticked down to 3 seconds, Joseph Young rose up for the kill shot with his last of five 3-pointers to give Oregon an 11-point lead en route to a 71-59 victory over the Beavers on Saturday night.
Young finished with 27 points, including 11 in the first five minutes of the second half, as the Ducks (11-3, 1-0 Pac-12) won their sixth straight game, giving them the longest winning streak in the conference with No. 8 Arizona coming to town next Thursday night.
''Joe did a great job,'' Oregon coach Dana Altman said. ''He was the difference in the game, there's no doubt about it.''
Young had plenty of help from Elgin Cook with 18 points and nine rebounds, and Dillon Brooks added 10 points.
Oregon's Jordan Bell proved effective off the bench with eight points, nine rebounds and five blocked shots. He's now within three of the school's single-season record for blocks with 48 in just 14 games.
Langston Morris-Walker scored 16 points to lead the Beavers (9-4, 0-1). Gary Payton II added 12 points and Olaf Schaftenaar had 10.
The Ducks were up 60-47 with 7:52 to play when Oregon State made its final run with a five-point burst to pull within eight.
First-year coach Wayne Tinkle then cranked up the pressure by putting his Beavers in a 1-3-1 zone defense, forcing Oregon to work the perimeter before the ball settled into Young's hands on the left wing, and then the net for a 63-52 lead.
Oregon State never got closer than nine points the rest of the way.
The Beavers came into the game second in the Pac-12 in defending the 3-point line at 28.6 percent, but the Ducks hit 6 of 13 overall with Young making 5 of 6.
''I don't know what to put a finger on, but at the end of the shot clock he made a lot of plays,'' Tinkle said, ''and a couple guys didn't know who it was, so you have to make sure you know where their best players are at all times.''
Oregon enjoyed a 35-28 rebounding advantage behind Cook and Bell. The Ducks finished the game shooting 48.9 percent from the field after going 11 of 20 (55.0 percent) in the second half.
With Young, Cook and Bell doing all their early scoring, the Ducks broke to a 10-0 lead and were up 20-9 with seven minutes left in the first half. The Beavers, who made only 2 of their first 18 shots from the field, stayed that close only because Oregon kept putting them on the foul line.
But Oregon State, which closed the half on an 18-9 run, pulled even at 27-27 on Morris-Walker's banked 20-footer with less than a minute to go. If Jarmal Reid hadn't missed two point-blank shots in the final five seconds, the Beavers would have left the floor tied instead of down 29-27.
Oregon State: The Payton family is now 9-2 against the Ducks with Saturday's loss. The elder Payton, a consensus all-American in 1990 and a Naismith Hall of Fame inductee in 2013, went 9-1 against Oregon in four seasons (1986-90) as a Beaver.
Oregon: Joseph Young's 27 points were the most he's scored since he went for 32 in the Ducks' season-opening win over Coppin State. It was Young's eighth game with 20 or more points this season and raised his Pac-12 leading average to 20.1 points per game.

THAT NEW CIVIL WAR SMELL
Not only was it Oregon State coach Wayne Tinkle's first taste of the most-played rivalry in college basketball with the 343rd meeting between the schools, his entire starting lineup was new to the Civil War, too. That might have contributed to the Beavers, who have no seniors, missing their first nine shots as they fell behind 10-0.
BELL TAKES HIS TOLL
Oregon's best weapon off the bench is turning out to be Jordan Bell, a defensive force who, in addition to his five blocks, was credited with 15 pass deflections. ''That's pretty intense,'' Young said. ''I wish I could get that from him every day.''
PAYTON'S PLAY GETS A RISE
Gary Payton II had 12 points, five rebounds and five assists in his first Civil War. However, the play that drew the most reaction from the crowd of 7,314 came midway through the second half when his breakaway dunk off a steal turned into nothing but two hands full of rim as the ball ricocheted back to the Ducks.
