LOS ANGELES — Oregon senior Lexi Bando made her final game at Pauley Pavilion a grand one.

She hit a 3-pointer from the left wing with 59 seconds left for the dagger in No. 9 Oregon's 70-61 victory over No. 14 UCLA on Sunday night.

Ruthy Hebard scored 19 points, Sabrina Ionescu had 18 and Maite Cazorla 17.

The Ducks (15-2, 4-0) won for the seventh consecutive game and remained perfect in conference play. Their 4-0 start is the best start in conference play since 2001.

"That sealed the game," Hebard said about Bando's 3-pointer. "It made us really pumped up. I'm really glad she made that three. It's really good for her and all of us."

Bando's 3-pointer gave the Ducks a 63-59 lead, and she iced the game with a pair of free throws with 40 seconds left. Bando is from Eugene and her family was on the trip to California.

"She doesn't get free very often in L.A. (to shoot)," Oregon coach Kelly Graves said. "A wide open 3-pointer for Bando is like a layup for most people. That's what you need out of your senior. I'm happy for her. Her family came down for this trip. It was her last go-round at Pauley Pavilion."

Bando has the best active career 3-point shooting percentage in the NCAA at 45.7.

The Bruins (11-4, 2-2) had won a school-record 20 consecutive home Pac-12 games.

Monqiue Billings led UCLA with 22 points and 10 rebounds — her 37th career double-double and eighth of the season — and Jordin Canada added 19 points.

UCLA played a ranked opponent for the third consecutive game and won two of them.

"Two out of three is cool but 3 of 3 would've been better," Billings said.

Oregon opened on a 9-0 run. UCLA didn't score for the first 6:47 of the game but rallied. Canada ended the drought with a long range jumper from the right wing.

Oregon led 27-23 at halftime despite committing 12 turnovers.

UCLA took its first lead of the game at 34-31 on a Japreece Dean 3-pointer with 6:38 left in the third quarter. UCLA held its last lead at 59-58 before a free throw and Bando's big 3-pointer.

Oregon outrebounded UCLA 42-39 and managed to win despite 18 turnovers.

"There was a lot of frustrating parts," UCLA coach Cori Close said. "We missed 20 shots in what we like to call the war zone. We obviously struggled against their zone. That slowed us down. We weren't able to get some of the passion plays and turnovers and runouts. Their guards are tough. We said that after the Oregon State game, that we would have the exact same gameplan but that they would have better guards."

And one, Bando, delivered the knockout punch.

USC 65, No. 16 OREGON STATE 61: USC coach Mark Trakh moved forward Aliyah Mazyck to guard Oregon State's young backcourt in the second half and the move paid dividends. Oregon State had 27 turnovers, 16 of which came in the second half, and that proved to be the winning formula as USC scored 26 points off those miscues to rally from a 17-point deficit.

Kristen Stewart scored 21 points as USC came back to beat No. 16 Oregon State for its first Pac-12 Conference win at the Galen Center. Oregon State had as much as a 17-point lead in the third quarter. Sadie Edwards added 17 points and Jordan Adams and Mazyck each had four steals. Oregon State's trio of starting guards had 12 turnovers.

"I'm really proud of the kids because they were down against a nationally-ranked team that really runs their stuff well," Trakh said. "We needed to win a game like that where we grinded and came back and executed in the last four minutes. I'm really proud of what the kids did. Jordan played her tail off. We played with a sense of urgency but not a sense of panic"

USC (11-4, 1-3) snapped a three-game losing streak after rallying from a 17-point deficit in the third quarter. Simon made an open basket inside to give the Trojans a 62-61 lead with 54 seconds left. USC had taken its first lead of the second half with 1:34 left on a pair of free throws by Simon.

Oregon State (11-4, 2-2 Pac-12) was down by two after Minyon Moore made one of two free throws. A Katie McWilliams turnover — her only one of the game — against pressure by USC with eight seconds left ensured there would be no last-second heroics for the Beavers.

"They're very athletic," Oregon State coach Scott Rueck said. "We're young at the guard spot. They're veteran at the guard spot. I thought their pressure hurt us. They were very physical with us, forcing us into turnovers. Give them credit for making plays to get back in the game."

Marie Gulich scored a team-best 16 points and Mikayla Pivec added 14 for the Beavers. Pivec made a half-court shot at the first quarter buzzer to give the Beavers a 22-13 lead. USC was down 40-28 at halftime but was undeterred.

"It's a major (boost)," Edwards said. "On Friday we played Oregon tough but came up short. Oregon State is a good team. We made an adjustment. We stayed together. We stayed in it. We didn't drop our heads when we were down by (17) points. We believed in each other and our coaching staff believed in us. Aliyah was the MVP for us this weekend. Her defense changed the game."

Oregon State made 7 3-pointers in the first half, one in the second half. USC rallied in the third quarter with a 10-0 run —buoyed by turnovers on four consecutive possessions for Oregon State — and pulled within four points at 49-45.

"We just told the kids to pressure more. They run their stuff so well," Trakh said. "We had to force them out of their comfort zone and pressure them a little more ... We got some momentum going on our side. Sadie made some big shots. Kristen had 21 points and seven rebounds. Aliyah turned the game around with her defense. She really got after them. Really proud of Aliyah and all the kids."

The Trojans played three nationally-ranked teams in their last four games.
