EUGENE — Sabrina Ionescu scored 28 points and Ruthy Hebard had 15 points and 15 rebounds to lead No. 10 Oregon to a 92-74 victory over Oklahoma at the PK80 Invitational on Saturday.
Ionescu had 18 points in the second half and finished one off her career high for the Ducks (5-1) to go with seven rebounds and six assists. Maite Cazorla added 11 points.
Oregon had a 25-18 edge in bench points as Satou Sabally had 13 and Justine Hall 10.
Vionise Pierre-Louis led the Sooners (3-2) with 32 points and 13 rebounds, but Oklahoma was hampered by a 1-for-21 effort from 3-point range. Maddie Manning added 17 points and Ana Llanusa 12.
Each team grabbed 41 rebounds, with the Sooners holding a 21-13 edge on the offensive glass behind Pierre-Louis' seven.
The Ducks opened a 48-34 halftime lead thanks in part to Hall's three 3-pointers. Oregon was 7 of 14 beyond the arc in the first half while Oklahoma missed all 12 of its attempts.
Oklahoma went 25 of 34 at the free throw line, but it wasn't enough to overcome the hot-shooting Ducks, who finished 38 of 72 (52.8 percent) to the Sooners' 24 of 69 (34.8 percent).
Pierre-Louis made half of Oklahoma's field goals as the rest of the Sooners shot just 12 of 48 (25 percent).
Oregon topped 81 points for the fifth time in six games as sophomores Hebard and Ionescu continue their torrid start to the season. The Ducks came in second in the nation in assists (110) and had 20 more against the Sooners.
Oklahoma came in scoring 92.2 points per game and finished with a season-low 74. Senior Gabbi Ortiz was held to less than half her season average (15.8) with seven points after going 1-for-9 from 3-point range.
