CORVALLIS, Ore. -- It is first versus worst for the latest edition of the Civil War.
Sixth-ranked Oregon (26-4) takes a five-game winning streak to Oregon State (5-25) on Saturday as the Ducks look to clinch at least a share of a second straight Pac-12 regular-season championship.
The Ducks are tied for first place with Arizona at 15-2, and the Wildcats play a road game against Arizona State on Saturday afternoon.
If Oregon and Arizona end up sharing the regular-season conference title, the Ducks would get the No. 1 seed in the Pac-12 tournament because they beat Arizona 85-58 last month in the teams' only meeting.
"We have had a week off to rest and get better and we need to get better in a lot of areas," Oregon coach Dana Altman said. "Refocus and hope we are ready to go."
Oregon had to come from behind in the final three minutes last week to win 68-65 at California and 75-73 at Stanford.
"It stresses coach out, but it shows we can get gritty and get the win," Oregon senior guard Dylan Ennis said. "We keep fighting back and if we're down like that again, we can do the same thing."
Both Oregon and Oregon State had the week off to prepare for the final game of the regular season.
"Practice and get ready for Oregon State," Oregon freshman guard Payton Pritchard said. "That is what is on our mind now."
Oregon State is last in the conference at 1-16 as it tries to avoid becoming the eighth school to win no more than one conference game since the Pac-12 schedule expanded to 18 in 1978.
"We know Oregon is awfully talented, but we want to try to get off to a good start and take care of business at home and carry momentum into the Pac-12 tournament," Oregon State coach Wayne Tinkle said.
The Ducks beat the Beavers 85-43 in Eugene in January to give Oregon State its most lopsided loss this season. Oregon scored the first 21 points in that game.
"We played catch-up the whole time so hopefully we don't fall into a hole like that again," Beavers sophomore guard Tanner Sanders said. "We have to come out with more aggression instead of being passive and waiting for them to throw the first punch. They came out with more of a want-to attitude than we did. They acted and we reacted and we were down 21-0. That can't ever happen in a basketball game."
Oregon has won five regular-season conference championships in its history, but never in consecutive seasons.
"They mean a lot when you haven't won a lot of them," Altman said.
Oregon junior Dillon Brooks has one last chance to make his case for conference player of the year as he leads the team with 15.6 points per game. Sophomore guard Tyler Dorsey averages 12.8 points while senior center Chris Boucher is scoring 12.1 off the bench.
Ennis averages 11.1 points while junior forward Jordan Bell scores 10.8 points to go with a team-leading 7.8 rebounds.
Sophomore guard Stephen Thompson Jr. leads Oregon State with 16.4 points and 3.2 assists per game while sophomore forward Drew Eubanks averages 14.9 points and a team-best 8.4 rebounds.
