Las Vegas, Nev. -- Oregon women's basketball did enough to defeat Arizona in the quarterfinals of the Pac-!2 Tournament, 77-63.
It took a team-high 21 points from Orregon forward Ruthy Hebard to earn the victory, despite playing with a nagging knee injury.
"Ruthy is a force," head coach Kelly Graves said. "There's no question about it. When she's playing at her best she's one of the best post players in the country, certainly."
The Ducks shot 60 percent from the floor in the first half and 53.3 percent for the game. Oregon also ourebounded the Wildcats, 37-20. Ducks guard Sabrina Ionescu came up two boards shy of a triple-double after recording 18 points and 13 assists.
Oregon committed 13 turnovers but never trailed in the ball game.
The Ducks now advance to the semifinals to face a UCLA team that beat Oregon at Matthew Knight Arena on February 22.
"They obviously beat us a few weeks ago in Eugene so yeah, they're just so aggressive," Graves said. "I mean we didn't do so well against tonight's pressure and we're gonna see it tonight plus another level. Yeah got to make sure we pass it to the team in white."
Tip off is set for 6 p.m. on Saturday at the MGM Grand Garden Arena in Las Vegas.
Oregon State's quarterfinal game didn't end so well as the Beavers lost in the final seconds to Washington, 68-67.
OSU's Aleah Goodman's long three fell short at the buzzer.
Washington's Missy Peterson buried a three with 2.3 seconds to go but a technical foul after the Huskies' celebration gave the Beavers a pair of free throws. But the Beavers couldn't capitalize.
Mikayla Pivec, who tied the game with a layup with 4.9 seconds to play, scored a game-high 23 points.
Destiny Slocum and Taya Corosdale were the other Beaver players in double figures with 15 and 14 points, respectively.
OSU outrebounded Washington, 40-33, but shot just 27 percent from beyond the arc going 8-29.
"It was unreal just to see that much orange. For that reason I was most disappointed in was letting those people down tonight, which I kind of felt like we did," said Oregon State head coach Scott Rueck. "All the credit in the world to Washington though. They played a phenomenel game, they hit huge shots all game long, answered everything they did. I told Jody before the game last night I was impressed with the way they played. Not only did they play like they had nothing to lose. They executed."
