Sienna Betts and the third-quarter surge that turned nerves into a statement at Pauley Pavilion

At Pauley Pavilion, the first half felt louder than the score. UCLA was up 10 at the break against a No. 16 seed, but the mood carried the tension of expectations—until sienna betts helped turn the game into something unmistakable: a No. 1 seed playing like one.

What happened in UCLA’s NCAA tournament opener?

UCLA opened its NCAA tournament title bid with a 96-43 win over California Baptist, but the path to the blowout was not immediate. Coach Cori Close’s program emphasizes “thriving, not surviving, ” and a halftime lead of 10 points was a reminder that the standard inside the building is not simply to advance.

The second half erased any doubt. UCLA “locked in” for a 31-4 third quarter, one of its most dominant stretches of the season, and the game’s tone changed from uneasy to overwhelming. The Bruins improved to 32-1, extended their winning streak to 26 games, and moved on to a Monday second-round matchup against No. 8 seed Oklahoma State (24-9) for a spot in the Sweet 16.

How did sienna betts help shift the game from close to lopsided?

In a night shaped by size, rebounding, and second chances, sienna betts delivered her first career double-double with 10 points and 12 rebounds. The numbers landed in the same place her voice did: inside a team response that began before coaches entered the locker room.

Angela Dugalic, who finished with 10 points and 11 rebounds, described a halftime moment of player-led accountability. “I think in the locker room, it was made very clear to us that we needed to do a better job, and that was before the coaches came in, ” Dugalic said. She added that teammates across classes spoke up—“And Sienna. ”

For UCLA, the third quarter wasn’t just a scoring swing. It was the visible outcome of a reset—an insistence on precision and intensity after a first half marked by what Charlisse Leger-Walker called “too many mental lapses in the scout and how we wanted to game plan. ” Leger-Walker finished with eight points, five rebounds, and five assists.

Why did rebounding and size decide the margin?

California Baptist arrived with areas of strength, and its coach Jarrod Olson framed the first 20 minutes as proof of his team’s competitiveness. “In my opinion, that’s the best team in the country, ” Olson said. “For 20 minutes, we gave them all they could handle. ”

But the physical gap widened as the game went on. UCLA’s rebounding advantage—62-21—was powered by a height edge across positions and translated into a season-high 21 offensive rebounds. The Bruins also scored 54 points in the paint to the Lancers’ 14, building possessions into a flood of second chances and close-range finishes.

sienna betts pointed to that work as a safety net when shots are not perfect. “I’m really proud of that, ” she said. “Offense is not always going to fall and not always to be perfect, and it’s important to be able to rely on the little things and crash like that. ”

California Baptist’s tallest player, 6-foot-3 Emma Johansson, entered the day second in the country with 2. 86 blocks per game, but she finished with one block and one rebound while picking up four fouls. Chance Bucher led the Lancers with 11 points and said afterward the Bruins are a No. 1 seed for a reason.

What does the win say about UCLA’s mindset going forward?

The game carried a familiar warning for top seeds: a No. 16 seed has not upset a No. 1 seed in the women’s NCAA tournament since 1998, but early discomfort can still test focus. UCLA started one for five and did not take the lead until 3: 51 left in the first quarter, using a 10-0 run to finally tilt the floor.

From there, the Bruins’ response looked like the program identity Cori Close has demanded all season—especially when the margin wasn’t yet safe. The roster’s contributions also showed the shape of UCLA’s balance. Senior Lauren Betts produced a double-double with 22 points and 10 rebounds. Dugalic posted her own double-double. And in the middle of the team’s internal reset, a freshman’s presence in the conversation matched her work on the glass.

As Monday’s second-round game approaches in ET, UCLA carries forward a result that was not only a blowout, but also a reminder of how quickly a top seed can turn a shaky opening into a statement—when the accountability starts in the locker room and ends with the ball coming off the rim into Bruins hands.
