Oregon ends regular season with upset over No. 3 Arizona

Oregon opened the regular season with a 13-game win streak. They closed it with seven straight victories.

The Ducks may have stumbled in the middle, but reserve guard Jason Calliste says they still belong in the national conversation — especially after a 64-57 win over No. 3 Arizona on Saturday at Eugene, Ore.

Calliste made the go-ahead jumper and free throw with 4:22 left and finished with 18 points.

Aaron Gordon had 21 points for the Wildcats, who had already clinched the Pac-12 regular-season title.

at Stanford 61, Utah 60: Dwight Powell made a go-ahead free throw with 36.1 seconds remaining after the Cardinal missed seven in a row from the line late. The Utes couldn’t get a shot off in the waning seconds.

at Oregon State 78, Arizona State 76 (OT): The Beavers’ Roberto Nelson scored six of his 15 points in overtime. Jermaine Marshall’s three-pointer with 19.5 seconds left in regulation capped the Sun Devils’ rally from a 14-point deficit.

at California 66, Colorado 65 (OT): Justin Cobbs made a pair of free throws with 20.8 seconds left in overtime, and the Bears kept alive their slim NCAA tournament hopes.
