Arizona sank 11 of 30 3-pointers (36.7 percent), compared to 6 of 19 (31.6 percent) for Washington State. The 79 points allowed was a season high against the Cougars, who started the day ranked first in the Pac-12 with 59.6 points against per game.

Arizona raced to a 40-23 halftime lead behind the sensational outside shooting of Hill.
The Cougars, uncharacteristically sloppy, fired several passes directly to Arizona players in the early going. WSU made six turnovers in the first 7 minutes, 3 seconds, including three by Motum.
