LAS VEGAS — The Pac-12 Tournament is setting up to be a revenge tour for the second-seeded Arizona Wildcats. 

Second-seeded Arizona will face sixth-seeded Arizona State in the Pac-12 Tournament semifinals on Friday at T-Mobile Arena in Las Vegas, after the Sun Devils held off USC 77-72 on Thursday. 

It's the first time the Wildcats and ASU have played each other in the conference tournament since 2009, when the James Harden-led Sun Devils beat the UA, which had Chase Budinger, Jordan Hill and Nic Wise — and Russ Pennell was the interim head coach after Lute Olson retired. 

The last matchup between UA and ASU this season resulted in Sun Devils guard Desmond Cambridge Jr. sinking a 60-foot half-court shot to lift ASU to an 89-88 win at McKale Center. The victory marked the first time an unranked ASU team beat a ranked Arizona team at McKale Center. 

Cambridge had 27 points on 6-for-12 shooting from 3-point range on Thursday. 

Tip-off between the Wildcats and Sun Devils is scheduled for 9:30 p.m. on ESPN. Winner will face either top-seeded UCLA or No. 4-seeded Oregon.
