Iowa stunned No. 4 USC, 76-69, on the day of Caitlin Clark’s No. 22 jersey retirement. The Hawkeyes weren’t perfect, but their defense caused issues for the Trojans from the beginning.

Lucy Olsen led the way with 28 points. Her biggest moment came with 4:30 remaining as she picked up a steal and made a layup that injected more energy into Carver-Hawkeye Arena. This gave Iowa (15-7, 5-6 Big Ten) a 67-60 advantage and forced USC (19-2, 5-1 Big Ten) to call a timeout.

“It’s our moment,” Iowa coach Jan Jensen said in the huddle. “We are going to take it.”

And take it they did. Jensen’s team pulled off a huge signature win in her first season at the helm of the program. In the process, the Hawkeyes snapped USC’s 15-game winning streak and handed Lindsay Gottlieb’s team its first loss in the Big Ten.

USC entered the game right behind UCLA for tops in the Big Ten, but the Trojans’ loss muddied the picture. Ohio State now has a chance to pass USC in the Big Ten standings with a victory in their matchup next week, as both teams have one conference loss this season. That highly anticipated matchup is slated for 9 p.m. ET Saturday in Los Angeles.

USC couldn’t overcome a frigid start where they only scored one point in the first nine minutes. JuJu Watkins finally hit USC’s first field goal, a 3-pointer, with 26 seconds remaining in the opening quarter. By then, Iowa had already reached 18 points, while USC started 1 of 14.

In the second quarter, however, things looked brighter for USC as Watkins scored 15 points, including a buzzer-beater, giving her team a 29-28 advantage at halftime.

“What a play to end the half 😤”

It seemed USC was stealing the momentum as the Trojans found a six-point lead in the third quarter. However, Iowa’s defense was persistent.

The Hawkeyes adapted and didn’t allow Watkins to get comfortable; she only made three field goals in the second half, ending the game with 27 points.

USC finished with a shooting percentage of 35.4%, marking the team’s worst this season.

Caitlin Clark returned to Carver-Hawkeye Arena on Sunday to see her No. 22 Iowa jersey officially retired by the program. Clark, a two-time national Player of the Year, finished her college basketball career as the all-time Division I leading scorer with 3,951 points.

“There will never be another 22,” Clark said during the ceremony.

As expected, the arena was sold out for the postgame ceremony, celebrating one of the program’s legends.
