CORVALLIS, Ore. -- Deandre Ayton had 19 points, 12 rebounds and three blocks, and No. 14 Arizona, minus one of its star players, beat Oregon State 75-65 in overtime on Thursday night.
Rawle Alkins added clutch scoring with 16 points and eight rebounds, and Dusan Ristic had 14 points for the Wildcats (22-6, 12-3 Pac-12), who were without guard Allonzo Trier.
Trier was declared ineligible by the NCAA after a trace amount of a banned substance was found during a late January drug screening, according to a university statement released Thursday.
