TUCSON, Ariz. — Arizona went on a big run, then had a rash of turnovers and defensive mistakes to let Oregon back in it. The Wildcats again went on a big run, again allowed the Ducks to rally.

A third time put Oregon away.

Allonzo Trier scored 25 points, Deandre Ayton added 24 and No. 17 Arizona used that late run to outlast Oregon 90-83 on Saturday.

“It’s a huge win, especially since Oregon is rolling and had a huge win in Phoenix against ASU,” said Arizona’s Rawle Alkins, who had 13 points and six assists. “We had to protect our home court.”

It was all about the offense on Saturday, with two long, athletic teams trading runs throughout an entertaining game.

Arizona (14-4, 4-1 Pac-12) had the last one, scoring eight straight points to go up 84-77 with 72 seconds left. The Wildcats shot 53 percent from the field to beat the team that ended their 49-game home-court winning streak a year ago.

Oregon (12-6, 2-3) rallied from double-digit deficits three times but could not muster a final comeback to leave the desert with a split between the Pac-12’s two Arizona schools.

Elijah Brown scored 25 points and MiKyle McIntosh had 20 for the Ducks.

“The last four minutes were the difference,” said Oregon guard Payton Pritchard, who had 12 points and seven assists. “But I think we made a jump this week.”

Oregon had been in a funk before this week, losing two of its first three Pac-12 games, including a disheartening 76-64 setback against rival Oregon State.

The Ducks bounced back on Thursday with a strong all-around game, knocking off No. 11 Arizona State 76-72 for their first win as an unranked team against a top-11 team in 41 years.

Oregon dominated the Sun Devils in the paint, outscoring them by 22 inside while grabbing 15 offensive rebounds.

Arizona, with Ayton and fellow 7-footer Dusan Ristic inside, was a much bigger challenge, and the Wildcats played it to their advantage early.

Working the ball inside for shots at the rim and kickouts, the Wildcats jumped on the Ducks after opening with consecutive turnovers. Arizona hit its first six shots and blew past Oregon with a 17-2 run to go up 21-9.

“Those are some pretty big guys inside there,” McIntosh said.

The Ducks rallied after Arizona State went on a big first-half run and did the same thing against Arizona — twice. The second one, 12-0, pulled them within 32-31.

Arizona led 41-38 at halftime after both teams shot at least 50 percent.

The Wildcats kept the run trend rolling, scoring eight straight points to go up 51-40 early in the second half. Oregon took its turn, tying the game at 55-all.
