So much for role reversal.
Washington State's players walked into McKale Center in Tucson as the No. 6 team in the country Thursday and walked out losers after Arizona's resounding 76-64 upset.
Jerryd Bayless, who didn't play in three of Arizona's six losses because of injury, had 23 points and six assists and Chase Budinger scored 22 as the Wildcats buried Washington State from three-point range, making 12 of 21 (57.1%).
In stark contrast to last season, Arizona also made plays on the other end.
Jordan Hill blocked six shots, and Bayless' defense on Derrick Low helped hold Washington State's leading scorer to five points. He didn't score until 2:39 remained, and unlike in their loss to UCLA, the Cougars didn't have a desperate rally in them.
