Oklahoma went on a 12-3 run that included a three-point play by Campbell and McFarland's three 3s.
Ellenberg scored the Sooners' final 10 points of the first half. Thea Lemberger hit a 3 with two seconds left in the first half to cut it 42-37, but the Bruins didn't take full advantage of the potential momentum booster.
The Bruins got to within 42-41 with 17:52 left but Oklahoma answered with a 12-4 run that included 3s from Campbell and Ellenberg.
“UCLA played very hard, was very athletic and gave us all we wanted, but tonight we were just a little bit better,” Coale said. “I'm not sure I've been more proud of a group of kids before. They were so determined and absolutely refused to lose this game.”
The Sooners were out-rebounded 50-37 overall, including 23-13 on the offensive end, but it was an improvement compared to the earlier meeting between the teams, when UCLA won the offensive rebounding battle 27-6.
McFarland finished with 20 points and 16 rebounds, and Campbell added 19 points on 6-for-8 shooting.
“Who wouldn't want someone on their team who has 16 rebounds?” Campbell said of McFarland. “There is no other post player I'd rather have than Joanna.”
The Bruins got 18 points and eight rebounds from Atonye Nyingifa and 14 points from Markel Walker.
“We did a better job of not letting them rebound the ball,” Ellenberg said.
