UCLA used a 10-0 run to take a 12-4 lead on the Beavers with four minutes to play in the quarter. Osborne had eight of those 10 points, including back-to-back three-pointers to start the run. The Bruins went on another run, outscoring the Beavers 9-1 in the final 3:41 of the quarter, with Penn scoring seven of the Bruins’ nine to send UCLA into the second quarter with a 21-7 lead.

After Dugalić drained a three-pointer to start the second quarter, Oregon State began to come alive, scoring six straight points.

The Beavers then went on a 12-2 run to get within single digits, 33-25, and trailed by 10 at the half, 35-25.

Oregon State outscored the Bruins in the third quarter, 20-14, to close to within four, 49-45.
