TIP-INS

Arizona: Sophomore point guard Parker Jackson-Cartwright made his first college start when regular starter Kadeem Allen became ill. Allen played 7 minutes and fouled out after scoring two points. Standout freshman guardAllonzo Trier missed a seventh game with a hand fracture. The Wildcats hope Trier can play Saturday against Washington in his hometown of Seattle.

Washington State: Wednesday's loss assured the Cougars of a non-winning record in conference play for the 19th time in 21 years. The stretch began with a 9-9 mark in 1995-96. The current streak of eight non-winning conference seasons includes a 9-9 showing in 2010-11. Washington State has not finished above .500 overall since a six-year run of winning seasons ended in 2011-12.
