CORVALLIS, Ore. (AP) - Aleah Goodman had 22 points and No. 12 Oregon State snapped No. 2 Oregon's 17-game winning streak with a 67-62 victory on Monday night.
It was just the second loss of the season for the Ducks, who defeated the Beavers 77-68 on Friday in the first game of the rivalry series. Oregon (24-2, 13-1 Pac-12) was hampered by the loss of starter Ruthy Hebard in the first half with what appeared to be a right knee injury.
Destiny Slocum finished with 20 points and the Beavers (21-5, 11-3) preserved their nine-game winning streak over the Ducks at Gill Coliseum. Oregon hasn't won in Corvallis since 2010.
The Ducks moved up a spot to No. 2 in the AP rankings earlier in the day. It was the Ducks' highest poll position in school history. The Beavers dropped from No. 9 following the loss in Eugene on Friday, the opening game of the Civil War rivalry series between the two teams.
It was a tense final period. Ionescu's layup tied the game at 50 early in the fourth quarter.
and her jumper pulled the Ducks in front with 6:23 left in the game as the Beavers went on an inopportune scoring drought.
But Mikayla Pivec's layup for the Beavers tied it again with 4:25 to go and Slocum's jumper gave them back the lead. Maite Cazorla's basket pulled Oregon within 59-57 with 35 seconds left.
Katie McWilliams made a pair of free throws for Oregon State with 17 seconds left but Ionescu's layup kept the Ducks within two points with just over 10 seconds to go. Goodman made free throws before Ionescu missed on a 3-pointer but was fouled and made all three free throws to get within 63-62.
Slocum made two free throws and then Ionescu traveled sealing the win for Oregon State.
Hebard appeared to injure her right knee coming down on a rebound about halfway through the second quarter. She went to the bench and stretched it gingerly before a trainer wrapped it with ice.
Hebard, who averages 16.8 points and 9.1 rebounds for the Ducks, headed to the locker room before the first half was over. She warmed up with the team after the break but did not play again.
Both teams wore pink on the annual Play4Kay day for the Kay Yow Cancer Fund, named after legendary North Carolina State basketball coach Kay Yow, who died of breast cancer in 2009.
