Ionescu, No. 8 Oregon beat No. 18 ASU, stay atop Pac-12

EUGENE, Ore. -- On a near-record shooting night for No. 8 Oregon, it was still the Ducks' defense that made the difference.

Sabrina Ionescu scored 26 points and Ruthy Hebard added 20 to lead Oregon to a 74-64 victory over No. 18 Arizona State on Sunday night.

Just as they had against Arizona two nights earlier, the Ducks gave up only five points in the third quarter.

"I think we need to come out dialed in defensively," Ionescu said, "and I don't think anyone can stop us."

Maite Cazorla had 15 points and Satou Sabally scored 10 for the Ducks (17-2, 6-0 Pac-12), who won their ninth consecutive game and snapped a four-game losing streak against the Sun Devils (13-5, 4-2).

Oregon broke open a close game by starting the third quarter on a 19-2 run as Arizona State missed seven of its first eight shots and committed six turnovers in the first 8 1/2 minutes of the second half.

"Disappointing," ASU coach Charli Turner Thorne said. "We haven't played that bad this year.

"That was uncharacteristic the way we turned the ball over. . Our starting backcourt just kind of struggled tonight, and this is not a backcourt you can struggle against."

Kianna Ibis had 22 points to lead the Sun Devils. Courtney Ekmark added 15 points and Charnea Johnson-Chapman had 12.

ASU was missing its second-leading scorer, sophomore Jamie Ruden, who suffered a concussion in the third quarter of Friday's loss at Oregon State.

"She's a matchup nightmare," Turner Thorne said of her top reserve, "and our best 3-point shooter."

Hebard was too much for the Sun Devils inside, going 9 of 9 from the floor for her third perfect shooting game of the season. Hebard came into the game fourth in the nation in shooting at 66.9 percent, and she's now at 75.8 percent in conference games.

"She has teammates who are getting her the ball. So she can just catch and score," Oregon coach Kelly Graves said. "She just has to catch the ball, it's that easy. I'm really proud of Ruthy. She keeps improving."

The Ducks threatened their school record for shooting accuracy and finished 31 of 47 (66 percent). ASU was 23 of 55 (43.6 percent).

Cazorla had 11 points and three of Oregon's five 3-pointers in the second half, and she and Ionescu each had five assists.

"She's a calming influence," Graves said of Cazorla. "She's our rock. She's the player we always count on."

Oregon made 10 of its first 13 shots and led by 13 points in the second quarter before the Sun Devils closed with a 13-4 run to trail 38-34 at the half.

BIG PICTURE

Oregon holds a one-game lead on unranked Stanford and is up two games on four other teams with its best start ever in the Pac-12. Rivalry week looms with two games against Oregon State for the Ducks, who are 0-6 against the Beavers under Graves.

Arizona State shares third place in the Pac-12 with three other ranked teams and plays four of its next six conference games at home.

POLL IMPLICATIONS

Oregon's all-time-high No. 8 ranking could improve after the weekend sweep and losses by three teams ranked above the Ducks. "I think they could be ranked higher, I honestly do, I'm not just saying that, in terms of some teams in the country," Turner Thorne said. "They've got all the pieces."

STAT OF THE NIGHT

Oregon was 8 of 11 from the field as it pulled away in the third quarter and was 25 of 35 (71.4 percent) entering the fourth before cooling off to miss the school record for accuracy (69.6 percent) set 18 years ago.

SHE SAID IT

Turner Thorne said the biggest difference in Oregon this season is on defense. "Last year they were more of a score-more team, and this year they're really working hard to be more aggressive and lock teams down," she said. "They're legit."

TIP-INS
