TUCSON, Ariz. (AP) - Salim Stoudamire can be deadly from long-range. Hassan Adams can jump as high as necessary to make his mark.

Both were at their best Thursday night - scoring 20 points apiece on 16-of-21 shooting - in 14th-ranked Arizona's 109-75 rout of Oregon State.

It was the 21st loss in a row for the Beavers at McKale Center. Oregon State hasn't won at Arizona since 1983, the season before Lute Olson became the Wildcats' coach.

Arizona has consecutive one-sided victories over UCLA and Oregon State since its loss at USC a week ago.

"We definitely sent a message," Arizona freshman point guard Mustafa Shakur said. "We are definitely one of the best teams in the country, but we have to play that way and show it. We need to rip a team apart from beginning to end."

Arizona shot a season-high 63 percent (43-for-68) in its biggest offensive outburst since a 112-81 victory over Washington on Feb. 5, 1998.

Stoudamire made seven of nine shots, including a season-high five 3-pointers in six attempts, to move into a tie for fourth on Arizona's career list for 3-pointers with 191.

"Salim is in a positive mode," Olson said. "You can just see it out there. He's happy for the team playing well. His New Year's resolution of being positive is important to him, and it's really important to us."

Adams, 9-for-12 shooting, had 10 rebounds and four second-half blocks.

"A block is way more fun than a dunk," Adams said. "It's defense. If you get a big block it rolls after that. A dunk is all love, but once you get the block, it's all defense."

The Wildcats (12-3, 4-2 Pac-10) put away the Beavers with a 36-8 run late in the first half and early in the second.

"When they are going like that, it is going to be hard for anybody to beat them," said Oregon State coach Jay John, Olson's former assistant.

Andre Iguodala had 19 points, eight rebounds and seven assists for Arizona. Chris Rodgers added 12 points and a career-high seven assists.

Chris Stephens scored 16 points, J.S. Nash had 15 points and seven assists and Jim Hanchett had 12 points and 10 rebounds for Oregon State (8-8, 2-4).

Arizona outscored the Beavers 20-6 over the last 6:08 of the first half and 16-2 through the first 3:48 of the second to open a 28-point lead.

"Everybody played awesome," the Wildcats' Channing Frye said. "We made the extra pass. We came out with a lot of intensity."

Stoudamire made all five of his shots in the first half, four of them 3-pointers.

His three consecutive 3s punctuated a 20-4 spurt that put the Wildcats up 48-32 with 1:42 to go in the half, and Arizona led 48-34 at the break.

The Wildcats made six of their first seven shots in the second half in a 16-2 run to go up 64-36 after Adams' 3-pointer with 16:12 to play. Arizona led by as many as 36 after that.

The Beavers stayed with the Wildcats early and led 27-26 on Nash's driving layup with 7:18 left in the half. It was tied at 28 after Kyle Jeffers made one of two free throws with 6:37 left.

Adams' rebound basket put Arizona up for good at 30-28 with 6:08 to play, and his inside basket made it 39-32 with 2:57 to go in the half. Stoudamire took over from there, swishing his first two 3s.

Adams made seven of nine shots in the first half, most of them inside, as the Wildcats shot 65 percent (20-for-31).
