EUGENE, Ore. (AP) — Satou Sabally scored 21 points, Sabrina Ionescu had 15 points and 11 assists and No. 7 Oregon beat No. 18 Oregon State 75-63 on Sunday night.

The Ducks (18-3, 7-1 Pac-12) broke the game open with a 28-11 second quarter and led by as many as 27 points to snap a 14-game losing streak against the Beavers (14-5, 5-3). Maite Cazorla had 16 points and Mallory McGwire 14 for Oregon.

Kat Tudor scored 17 points and Marie Gulich 16 for Oregon State after they had combined for 62 points in the Beavers' 85-79 overtime win Friday.

The Ducks set the tone with defense, holding OSU to 25 percent shooting (6 of 24) in the first half. The Beavers had no points in the paint by the break, and the nation's best 3-point shooting team was only 1 of 7 as Oregon built a 40-18 lead.

Ruthy Hebard's 10 rebounds led the Ducks to a 41-30 edge on the boards. They also outscored the Beavers 32-14 in the paint.

BIG PICTURE

Oregon, the fourth No. 1 seed in first NCAA ratings released Thursday, leads the Pac-12 by a game over UCLA and Stanford. However, the Ducks will continue to tinker with their rotation without injured 3-point specialist Lexi Bando, the NCAA's active career leader beyond the arc at 45.5 percent.

Oregon State has work to do with three conference losses and six of its last 10 games on the road if it hopes to claim a fourth consecutive Pac-12 regular-season championship.
