LAS VEGAS–USC couldn’t pull off a second upset victory over sixth-ranked Arizona in less than a week.
Oumar Ballo had a double-double, KJ Lewis scored a team-high 15 points off the bench, and the regular-season champion Wildcats put on an impressive defensive display in a 70–49 victory over the Trojans in a Pacific-12 Conference Tournament quarterfinal game Thursday at T-Mobile Arena.
