Washington State shot 51% from the field and 50% from behind the arc, while the Wildcats hit just 21% from three-point range.
Arizona took most of the second half to claw back and took the lead with 7:44 with a pair of Shakur free throws but WSU promptly scored the next six points to build back up their lead. The Cats did their best to come back. Down six with just over 2:00 to play, Mustafa Shakur nailed a three pointer to trim the lead to 66-63. Despite giving up an offensive rebound Arizona forced a turnover and went back on the attack.
Marcus Williams missed a three pointer, but Shakur gathered in the rebound and found Jawann McClellan in the corner for another three point attempt. McClellan missed his try but Chase Budinger grabbed the offensive rebound and was fouled on the ensuing shot but made just one of two foul shots.
After calling a time out Daven Harmeling worked himself open and buried a three pointer to put the Cougars back up by five.
The Cats drew another foul and Williams made both free throws, but the Cats could not foul and Harmeling made a lay-up and picked up the foul to ice the game.
Ivory Clark led the Cougars with 18 points, while Chase Budinger led the Cats with 19 points,
