Coming off a 51-point loss, not many gave the Oregon State much of a chance to come into Mac Court and win the final Civil War in the age-old building. Not many - but that number didn't include the Beavers.

Oregon State (7-8, 1-2) came out with more fire and determination to defeat Oregon 64-57 Sunday night in front of 8,217.  Seth Tarver and Daniel Deane led the Beavers in scoring with 15 points apiece. Roeland Schaftenaar added 11.

"I think we kind of got rattled," said Tajuan Porter, who led the Ducks with 20 points. "It was a shock to all of us. We committed a couple of turnovers and gave them momentum."

The Beavers opened the game up with an 8-0 run and the Ducks played not quite catch-up the rest night. Oregon had trouble with the Beavers 1-3-1 zone press, particularly sophomore point guard Malcolm Armstead, who had six of the Ducks' 12 turnovers.

"They play their 1-3-1 and if you handle it, they take it off," Duck coach Ernie Kent said. "If you don't handle it, they stay with it. We were so careless with the basketball early on .so lackadaisical with the basketball; it really hurt us in the game."

Oregon State maintained a single-digit lead for the whole game, but Oregon could never get over the top. The Ducks shot a measly 7-for-24 (29.2 percent) from the field in the first half and went into the halftime locker room trailing 31-24.

Coming out of the locker room, Oregon played with more energy and possibly a sense of urgency, but when the Ducks would pull within three points, the Beavers found an answer to keep the Ducks at arms length.

Oregon cut the deficit to one at 37-36 with 15:32 left on a Porter lay-up, but OSU answered right back with six straight points to push their lead to 43-36.

Porter brought the crowd back into the game when he hit a three from the right wing to bring the Ducks to a one-possession deficit at 51-48 with 7:32 left.

And yet again, the Beavers had an answer with six straight points. Oregon was then forced to put the Beavers on the foul line to extend the game and the Beavers made their free throws down the stretch to grab the victory.

After winning two games in Washington, the Civil War loss was disheartening for the Ducks. They weren't able to play the brand of basketball they prefer. The Beavers slowed the pace and forced Oregon to play 35 seconds of defense every possession.

"I thought they (OSU) were very good at executing their game plan," Kent said. "They kept the press on. They disrupted the game. They controlled the tempo of the game."

Obviously part of the Beavers' game plan was to control Michael Dunigan and to not let the 6-11 Oregon center have his way in the paint. Early foul trouble certainly helped that cause, but Dunigan never found the groove he enjoyed last weekend. He wound up with just eight points and eight rebounds.

"I tried to get into the seam of the zone in order to score," Dunigan. "But I started off wrong with early foul trouble. But defense wins games and we didn't have our mind sets like we were supposed to."

It was a tough lesson to learn and Oregon has just four days to take that lesson to heart as Arizona State comes calling Thursday night at 5:30.
