LAS VEGAS -- The only time No. 7 Arizona played fifth-ranked Oregon this season, on Feb. 4, the Ducks rarely missed a shot in an 85-58 rout in Eugene, Ore.
Both teams enter the Pac-12 tournament championship game on Saturday night at T-Mobile Arena with 29-4 records, and they shared the regular-season conference title.
In their matchup five weeks ago, Oregon shot 65.2 percent from the field and 64 percent from 3-point range, making 16 of 21 from beyond the arc before missing the last four shots.

Tyler Dorsey, who once committed to Arizona during the recruiting process, made all six of his 3-pointers and Dillon Brooks was 4 of 7.
Brooks went so far to say the shooting display was "ridiculous."
"I think you can't take too much from that game," Arizona guard Allonzo Trier said after scoring 19 points in the Wildcats' 86-75 win over UCLA in a Pac-12 tournament semifinal game on Friday night at T-Mobile Arena.
"They couldn't miss. It was one of those games."
Arizona ranks 27th nationally defending the 3-pointer, allowing opponents to make only 31.3 percent of their shots from that far. Oregon ranks 58th in the nation shooting 38 percent from beyond the arc.
UCLA entered Friday's game ranked fourth, making 41.3 percent. The Bruins made only 4 of 25 attempts (16 percent) in the loss.
When Arizona coach Sean Miller was asked what needs to be different against Oregon this time around, he answered, "I mean, they have to miss a few shots, man. They went on a roll like I've never seen before."
The championship game is significant in terms of where the winner will be placed in the NCAA tournament. The champion may be the No. 2 seed in the West behind West Coast Conference champion Gonzaga, the likely No. 1 seed.
"Location is important," Oregon coach Dana Altman said. "We played Wisconsin in Milwaukee. That wasn't much fun, so some of those things do matter.
"But you've got to go play the game, whoever you get matched up with, you've got to figure out a way. So we would like to win the conference tournament. Whatever implications those have on our seeding, I don't know. But we'd like to win the conference tournament again."
Arizona guard Kadeem Allen said it is imperative for the Wildcats to stay in the West after they were eliminated last year in Providence, R.I., in the first round by Wichita State.
"It felt strange like we were out on our own, out of our element," Allen said. "We want to be around our fans and stay close to home. In order to that, we must take care of business against Oregon."
Oregon forward Jordan Bell, who had 15 rebounds and five blocked shots in the semifinal win over Cal on Friday, said the Ducks have something to prove because they shared the regular-season title with Arizona.
"Winning this title means a lot, obviously, because you obviously want to win the regular season and the tournament to show that it's not a fluke," Bell said.
