LAS VEGAS (AP) - Elgin Cook scored 22 points and No. 8 Oregon survived a wild closing sequence in regulation to beat No. 15 Arizona 95-89 in overtime Friday night in the Pac-12 semifinals.
Oregon (27-6) led by 17 early in the second half, but Arizona (25-8) charged back and tied it in improbable fashion.
Oregon's Chris Boucher missed two free throws with 12 seconds left, and Arizona's Gabe York followed with a 3-pointer after gathering a rebound. Mark Tollefsen stole the inbound pass and was fouled, but hit just 1 of 2 free throws to send the game to overtime.
The Ducks dominated overtime, going up six on 3-pointers by Dwayne Benjamin and Dillon Brooks to earn a spot in Saturday night's championship game against No. 24 California or No. 12 Utah.
Tyler Dorsey had 19 points and Brooks 17 for the Ducks, who had 11 blocked shots and 10 steals.
