Sophomore forward Rui Hachimura matched his career high of 20 points on 8-of-10 shooting for the Bulldogs (15-3, 5-0 WCC), who defeated the Pilots for the ninth consecutive time. Sophomore forward Killian Tillie added 15 points and junior guard Josh Perkins contributed 13 points and seven assists as Gonzaga topped 100 points for the sixth time this season.

Melson knocked down five 3-pointers in the first 6 1/2 minutes of the second half as Gonzaga turned a 16-point halftime edge into a 68-39 lead.

"Today my shot was falling," Melson said on a postgame interview on ROOT. "It was just my number."

Melson's first 3-pointer of the second half pushed the margin to 50-30 with 18:48 left and he connected on another exactly one minute later to make it a 22-point advantage. He drained two more in the ensuing 64 seconds to make it 61-37 and nailed the final one of the stretch to boost the lead to 29 with 13:32 to play.
