Seattle slowly pulled away over the first 20 minutes, taking a 30-17 lead into halftime.
Sacramento State's Dylan Garrity made a 3-pointer with 10:44 remaining to make it 46-39, but a layup by Flora and back-to-back 3's by Umipig pushed the Seattle lead back to 15 with 7 minutes to play and the Hornets never again threatened.
