LAS VEGAS -- Catarina Ferreira finished with 16 points and 12 rebounds, and the Oregon State women's basketball team wrapped up its first season in the West Coast Conference with a tournament championship, ending two-time defending champion Portland's 13-game win streak with a 59-46 victory on Tuesday.
The fourth-seeded Beavers (19-15) earned the automatic berth in the NCAA tournament a day after eliminating top-seeded Gonzaga 63-61 in the semifinals. Oregon State has gone 19-13 in 13 previous trips to the NCAA tournament with a Final Four appearance in 2016.
Ferreira made 5 of 12 shots with a 3-pointer and 5 of 9 free throws for Oregon State. AJ Marotte scored 11 on 3-for-12 shooting.
Maisie Burnham totaled 16 points, 5 rebounds, 4 assists and 4 steals to pace the second-seeded Pilots (29-4). She was 3-for-12 from the floor and 9-for-10 at the foul line. Alexis Mark had 11 points and 5 rebounds.
Burnham had 6 points to guide Portland to a 13-9 lead after one quarter. Oregon State outscored the Pilots by 14 in the second quarter for a 27-17 lead at the intermission.
Sela Heide grabbed an offensive rebound and scored to give the Beavers their largest lead at 39-25 with five minutes left in the third quarter. Burnham scored Portland's final five points at the foul line and the Pilots trailed 42-32.
Portland whittled away at the deficit and Emme Shearer's 3-pointer pulled the Pilots within 47-41 midway through the final quarter. Ferreira answered with a second-chance layup to spark a 6-0 run, and Oregon State cruised from there.
The Pilots have six overall appearances in the NCAA tournament -- losing in the first round each time.
The Beavers won three straight Pac-12 tournaments from 2015 to 2017.
