The Lopes used their bench early, and with the game tied at 9-9, Grand Canyon (2-1) went on a 13-3 run and maintained control the rest of the way. Damari Milstead, Tim Finke, Roberts Blumbergs and Matt Jackson finished with a combined 31 points off the bench to help secure the win. Milstead lost his starting job to graduate transfer Trey Drechsel, who struggled shooting and finished 3 of 9 from the floor.
The Antelopes had 52 rebounds (21 on offense) to the Dolphins' 25. Jacksonville's tallest player, David Bell, played only 13 minutes due to foul trouble.
GCU shot 34 percent in the second half after shooting 48.5 percent in the first half, but the Antelopes made 11 of 14 free throws in the second half.
