Oregon vs. Indiana

When: TBA Sunday

EUGENE — While Satou Sabally crashed the boards, Sabrina Ionescu provided a little comic relief.

Sabally had 21 points and a career-high 16 rebounds to help second-seeded Oregon to an easy 78-40 victory over No. 15 seed Portland State on Friday night in the opening round of the NCAA Tournament.

Ionescu put the home crowd at Matthew Knight Arena on its feet with a stunning 3-pointer at the start of the second half and finished with 12 points and eight assists for the Ducks (30-4). Ruthy Hebard had 22 points and 12 rebounds.

Ionescu, the NCAA career triple-double leader, had her teammates cracking up in the final moments when she caught a ball that was mistakenly passed to her out of bounds on the bench — and she shot it. She was given a technical.

“That was just Sabrina being Sabrina,” Hebard laughed later, then shot a glance at coach Kelly Graves. “It was funny.”

Graves said: “Everybody can make one mistake. That was her one.”

Ashley Bolston had 19 points for the Vikings (25-8), making their first tournament appearance since 2010.

Oregon advances to play 10th-seeded Indiana (21-10) on Sunday. The Hoosiers won Friday’s earlier game over No. 7 seed Texas 69-65.

“We didn’t come to Oregon just to beat Texas. There’s more to do for this group,” Indiana coach Teri Moren vowed.

Oregon was coming off a 64-57 loss to Stanford in the Pac-12 tournament championship game. But that was back on March 10, and the Ducks had time to recover from some nagging injuries that caught up with them in Las Vegas.

The Vikings were coming off a thrilling 61-59 victory over Eastern Washington in the Big Sky tournament last Friday that earned them the automatic bid. Desirae Hansen drained a 12-foot jumper with 3.1 seconds remaining for the win. Portland State knocked top-seeded Idaho out in the semifinals.

The Vikings’ 25 wins this season were the most for the program since joining the Big Sky for the 1996-97 season. Portland State’s only other trip to the NCAA Tournament was in 2010.

“They’re just a really good team, so they just came out and played basketball,” Bolston said about the Ducks.

Oregon went to the Elite Eight for the second straight year last season but fell to eventual champion Notre Dame. Oregon is 6-2 in NCAA Tournament games under coach Kelly Graves.
