EUGENE -- By ending a seven-year losing streak, Oregon remains on track to snap a drought that's even longer.



Oregon's hot shooting and harassing defense Sunday turned the rematch of Friday's overtime thriller into a blowout for much of UO's 75-63 win -- its first over Oregon State since Jan. 23, 2011, ending a 14-game losing streak.



After suffering their first loss of Pac-12 play Friday in overtime in Corvallis, the seventh-ranked Ducks remain alone in first in the standings as they seek the program's first conference title since 2000. Freshman Satou Sabally scored a game-high 21 points in front of 7,249, the second-largest crowd to watch a women's game at Matthew Knight Arena.



Two days after OSU's Kat Tudor and Marie Gulich combined for 62 points, Oregon's man-to-man defense held them to 33. And two days after Oregon coach Kelly Graves shook his head recounting the ways the Beavers duo had torched his defensive game plan, he arrived for a postgame meeting with reporters with a mile-wide smile.



"I think that first 20 minutes is as good a defense that has ever been played in this arena since I've been here," said Graves, who earned his first win in the rivalry as Oregon's coach. "I was really proud of how hard we played.



"That's a great win, great win."



Sabally, a freshman whose recruitment came down to Oregon and Oregon State, said she was "very upset" in helping to allow Tudor to shoot at will Friday in an emotional, and narrow, loss. But when UO gathered for its shootout Saturday, Graves didn't sense a hangover from the overtime defeat.



"I liked our demeanor," he said. "I thought this morning they were ready. You could tell."



In hindsight, perhaps UO's biggest struggle between games was processing the pep talk given Saturday by the loquacious Bill Walton.



"I just introduced him," Graves said, "and on he went."



A 10-0 run pushed Oregon ahead 12-7 after one quarter, and midway through the second Satou Sabally's back-to-back threes, from the top of the arc and corner in front of Oregon State's bench, were followed by Mallory McGwire's midrange jumper for an 8-0 run and a 22-9 lead.



Sabally hit another three-pointer for a 29-14 lead before Gulich was called for a three-second violation on the next possession -- her hands tied up by Ruthy Hebard and Anneli Maley's defense. Graves joyfully pumped his fist in front of the scorer's table.



Oregon capped a 26-7 run to lead by 22 at halftime.

"The story of this game is we could not score," OSU coach Scott Rueck said. "They got to shoot and the basket looked like the ocean, throwing the ball in because there was no pressure on them."



After allowing nine threes in the first half alone Friday, Oregon forced OSU -- the nation's more accurate three-point shooting team -- into 1-of-7 shooting from behind the arc in Sunday's first half and 7-of-21 overall. OSU shot 37 percent from the field.



The Ducks, meanwhile, were buoyed by their finishes to each half. In the second and fourth quarters combined, they made 65.5 percent of their shots.



With Tudor unable to find open three-point looks, Gulich often doubled by UO's Hebard and Mallory McGwire and point guard Mikayla Pivec on the bench after earning her second foul early in the second quarter, Oregon State had no rejoinder until there was too little time to make up too great a difference.



"We were just a little overwhelmed," said Gulich, who had 16 points, 10 rebounds and three blocks. She called herself surprised how often and aggressively she was double-teamed on the block. "Friday they were a little softer in the post definitely. Today was a lot more physical."



The Ducks (18-3, 7-1 Pac-12) led by as many as 27 midway through the third quarter against an OSU defense that has held opponents to the nation's fourth-lowest shooting percentage.



But Oregon State (14-5, 5-3) also is one of the country's very best offensively, too, with field-goal and three-point shooting that each rank among the nation's top three. Two weeks after a humbling 35-point loss at UCLA, Oregon State fought back Sunday with a smaller lineup and trailed by just 12 early in the fourth quarter. OSU reserve guard Aleah Goodman scored all but one of her 11 points after halftime.



"UCLA, we just kind of gave up, honestly, that's what we did," Tudor said. "But this game, we didn't give up. We kept on fighting."



Graves blamed his conservative play-calling as the reason Oregon limped to the end of the third quarter, the team missing its final seven shots.



UO point guard Sabrina Ionescu, as she has so often during her young career, provided the answers.



Struggling to keep her pivot foot at the top of the arc amid a double-team, her shovel pass found a wide-open Sabally for a layup and a 62-46 lead with 7:32 remaining. Two minutes later, her cross-court assist found Maite Cazorla for a three-pointer from the wing and a 71-54 lead. They were two of her 11 assists, to go with 15 points.



In 85 total minutes Friday and Sunday, Ionescu committed just two turnovers and, for the first time since she was in middle school, helped turn the one-sided rivalry back toward UO.



"We don't really pay attention too much to what the streak is," she said. "But, it's kind of nice to shut their crowd up, shut their fans up.



"It was fun at their place, and even more fun here."
