BYU responded with 10 straight points, and Hardnett scored the final two baskets to move BYU with 72-68 with 3:14 left. A 3-pointer by Davis gave Stanford an eight-point advantage with 1:49 left, and the lead was 10 with 36 seconds left before the Cougars made one last charge.

Bryant knocked two 3-pointers late in the first quarter as the Cougars led 18-16 at the conclusion. BYU led by six early in the second quarter before Pickens and da Silva connected on 3-pointers to cap a 10-2 burst and give the Cardinal a 26-24 lead with 5:16 left.
Stanford led 30-29 after two free throws by Travis with 3:22 left before the Cougars rattled off the next 10 to take a nine-point advantage.
