EUGENE —

Long after Sabrina Ionescu collected her 18th career triple-double — in an NCAA Tournament game, no less — she stayed on the court at Matthew Knight Arena to sign autographs and pose for photos.

At one point a Ducks fan shouted her way: “Come back next year!”

The junior guard had 29 points, 12 assists and 10 rebounds and second-seeded Oregon defeated No. 10 Indiana 91-68 on Sunday night to advance to the Sweet 16 at the NCAA Tournament.

Already the NCAA’s career triple-double leader among both men and women, Ionescu has had eight this season alone.

She reached her latest on Sunday with just over two minutes left when she corralled a rebound on her own missed shot.

“Yeah, it was cool,” she said later.

“But I’m just honestly just really happy that we played really well. It’s so fun when you’re moving the ball. … And everyone scored tonight, so just being able to get that last game that we all have together here with this particular team on this home court was awesome.”

With speculation that she may turn pro at the end of this season, it may have been Ionescu’s final career game at Matthew Knight Arena. But it certainly will not be her last game in Oregon: With the win, the Ducks (31-4) advanced to face the winner of Monday’s game between South Dakota State and Syracuse on Friday at Portland’s Moda Center.

Satou Sabally added 19 points and eight rebounds for the Ducks, who are headed to the round of 16 for the third straight season. Oregon led by as many as 23 points.

Sabally said Ionescu’s low-key approach was typical.

“That’s the special thing about Sabrina, she really does not care about the stats. She doesn’t brag about it, she’s not the kind of person who is hunting stats. This is what makes her unique” Sabally said.

Ali Patberg had 16 points and Jaelynn Penn added 15 for the Hoosiers, who were hurt in the third quarter when Bendu Yeaney was injured and left the game.

Indiana was making its first appearance in the NCAA Tournament since the 2015-16 season and sixth trip in school history. The Hoosiers defeated Texas in the opening round.

“As good as Oregon is, could we have had a chance? Maybe, if we’d shot it a little bit better, but tonight Oregon was the better team, and they beat us,” Indiana coach Teri Morin said.

The winner of last year’s WNIT Tournament, Indiana was helped in its bid for an NCAA berth this season by a victory over No. 10 Iowa last month.

Penn had scored 24 points, including four 3-pointers, in Indiana’s 69-65 victory over seventh-seeded Longhorns on Friday.

Oregon easily dispatched No. 15 seed Portland State 78-40 in Friday’s other first-round game, shaking off a disappointing 64-57 loss to Stanford in the Pac-12 tournament championship game.

The Ducks have been to the NCAA Tournament for the past three seasons, including Elite Eight appearances in the last two.

Oregon used a 10-0 run to take an early 16-8 lead and was ahead 24-19 at the end of the first quarter. But Penn knocked down a 3-pointer that gave the Hoosiers a 28-24 lead in the second period.

Ionescu answered with her own 3 and was fouled for the four-point play to tie it at 28. She added another 3-pointer and pumped her fists as she ran back down the court.

She capped the half with a 3-pointer that made it 43-31 at the break and finished with five 3-pointers overall.

The Pac-12 Player of the Year went into Friday’s game averaging 19.4 points, 8.1 assists and 7.5 rebounds a game. It was her second triple-double in the NCAA Tournament; she also had one in the first round last year. She joins Stanford’s Nicole Powell as the only players with multiple tournament triple-doubles.

“I knew I had three rebounds in the third quarter and I wasn’t really happy with that, so I knew I had to get more,” Ionescu said. “And I had people telling me, you need a rebound, you need a rebound and so I had looked up and saw that I needed a few more, but that’s not necessarily what I was hunting, I was just happy that we were in the lead and we were playing well.”
