LAS VEGAS — Allonzo Trier scored 22 points, Dusan Ristic had 15 points and 11 rebounds, and No. 15 Arizona used a big second-half run to roll over Colorado 83-67 on Thursday in the Pac-12 quarterfinals.
Arizona (25-7) wasn’t exactly crisp on offense and Pac-12 player of the year Deandre Ayton had a rare quiet day. The Wildcats made up for it with scrappiness, earning a spot in the semifinals Friday against the Stanford- and UCLA winner.
Ayton missed numerous shots he typically makes, fouling out after scoring 10 points on 4-of-14 shooting and grabbing six rebounds.
