CORVALLIS, Ore. — Mikayla Pivec had 20 points and 12 rebounds and the fourth-seeded Oregon State Beavers withstood a major scare from No. 13 Boise State for an 80-75 overtime victory in the first round of the NCAA Tournament on Saturday night.

Aleah Goodman added 20 points for the Beavers (25-7), who advance to face fifth-seeded Gonzaga (29-4) on Monday. The Bulldogs defeated No. 12 Little Rock in the early game, 68-51.

Marta Hermida had 22 points for the Broncos (21-12), vying to become the first No. 13 seed to beat a No. 4 since Marist topped Georgia in 2012.

Destiny Slocom's layup gave the Beavers a 72-68 advantage in overtime and put the home crowd at Gill Coliseum on its feet. Slocom added another layup before Rachel Bowers' jumper for the Broncos cut the deficit to 74-70.

Bowers made free throws to get Boise State within two but then missed a pair with 33 seconds left. The ball went out of bounds under Boise State's basket and possession went to Oregon after a lengthy review.

Pivec converted free throws on the other end but Riley Lupfer made a 3-pointer to cut the Beavers' lead to 76-75. Goodman's free throws kept Oregon State in front and Lupfer missed a 3 that would have tied it.

Taya Corosdale closed it out for the Beavers with free throws for the final margin. She finished with 13 points and 15 rebounds.

Boise State trailed by as many as 14 points in the first half but pulled in front in the third quarter, outscoring the struggling Beavers 19-9.

The Broncos led 47-45 going into the final period of regulation, and Hermida's 3-pointer put Boise State in front 62-58 with 2:25 to go.

Pivec's layup got the Beavers within 64-62 with 47 second left. After the Broncos made free throws to go up 66-62, Pivec scored on a layup and then forced a jump ball with 9.4 second left.

Katie McWilliams was fouled on the inbound and hit both free throws to tie it at 66 with 8.5 seconds left and the game went to overtime.

The Broncos were making their third straight appearance in the NCAA Tournament and sixth overall. They have never won a tournament game.
