Kevin Pangos had 17 points on 5-for-8 shooting for the Bulldogs (11-2, 1-0), who have won 12 of the previous 13 conference titles. Kentridge High School product Gary Bell, Jr. continues to struggle, scoring only 3 points for the second consecutive game.
Gonzaga was without starting forward Sam Dower Jr., the team's second-leading scorer and rebounder, who was out with a back injury caused by a fall in a recent loss against Kansas State. Pangos, who was averaging a team-high 18.3 points despite dealing with a toe injury, also missed a stretch of the second half while receiving treatment.
Brandon Clark scored 22 points as the Broncos (7-7, 0-1) lost for the seventh consecutive time in Spokane.
