SEATTLE — Oregon freshmen combined to score 31 of the Ducks’ 33 points in a 70-63 comeback win over Arizona at the Pac-12 Tournament on Thursday night.

Oregon’s Sabrina Ionescu, the conference freshman of the year, tied the game at 46 with a 3-pointer early in the fourth quarter. The Wildcats (14-16) took a 50-48 lead when the Ducks (19-12) used an 8-0 run to take the lead for good, with freshman Mallory McGwire scoring on back-to-back trips.

“I didn’t want to lose this game,” said Ionescu, who led the Ducks with 22 points and five assists. “I was like I’ve got to do something to pump up the team, and I think that’s where that tie-up came in. From that moment, we just continued to build, and that’s what it usually takes — just one play to hype everyone up and help everyone believe.”

McGwire finished with 14 points, and fellow freshman Ruthy Hebard had 21 points and 12 rebounds as the Ducks snapped an eight-game losing streak in the Pac-12 Tournament.

Oregon, which is trying to shore up its NCAA Tournament résumé, gets a big chance Friday night against Washington and NCAA all-time leading scorer Kelsey Plum.
