PROVO, Utah -- Nick Emery scored 17 points, grabbed nine rebounds with five assists, and BYU dominated San Diego in a 91-33 win Saturday night.

It was the largest margin of victory of the season for BYU (21-8, 12-4 West Coast), which scored 20 of the game's first 22 points and took a 39-11 advantage into the break.

Zac Seljaas added 13 points and Kyle Collinsworth had 12 for the Cougars, who shot 57 percent (36-63), got 25 assists and went 12 of 27 from long range to notch their ninth game of the season with at least 10 3-pointers.

San Diego, which lost to BYU by just two points on Thursday, missed all 20 of its shots from 3-point range. The 20 attempts without a make are the most by a team in a game this season. The Toreros were just 14 of 57 from the field (25 percent).

None of the Torreros reached double figures.

Jito Kok led San Diego (8-19, 3-13) with six points and three blocks.
