Conor Clifford led the Cougars with 19 points.
TUCSON, Ariz. (AP) - Allonzo Trier scored 17 points in his first home game of the season, Lauri Markkanen had a double-double, and No. 7 Arizona pulled away late to beat Washington State 79-62 on Thursday night.
Trier scored 12 points against UCLA on Saturday in his first game back from a 19-game suspension for performance-enhancing drugs. He became more assertive after a quiet first half at McKale Center, scoring 11 points in the second to help Arizona (19-2, 8-0 Pac-12) finally shake the pesky Cougars.
Markkanen finished with 16 points and 13 rebounds in Arizona's 13th straight win overall and 17th straight at home.
