SPOKANE, Wash. -- Domantas Sabonis had 21 points and 13 rebounds, and Kyle Wiltjer added 18 points and 11 boards to help Gonzaga beat Division II Saint Martin's on Monday night after dropping out of The Associated Press Top 25 poll earlier for the first time since the 2013-14 season.

Gonzaga had lost two of its last three home games -- to then-No. 19 Arizona and now-No. 22 UCLA -- but the Bulldogs haven't lost back-to-back home games since 1995.

Freshman Bryan Alberts made his first start for Gonzaga (7-3), replacing struggling Silas Melson, and finished with 14 points on 4-of-5 shooting from 3-point range. Alberts entered the game having played just 78 minutes in nine games.

Gonzaga's starting center, Przemek Karnowski, missed his fifth straight game with a back injury.

Cole Preston scored 12 points for Saint Martin's, which was held to 18-of-54 shooting (33 percent), including 4 of 25 from 3-point range.
