CORVALLIS, Ore. -- With under eight seconds to play and down by two, the Oregon women's basketball team had two chances to tie or take the lead against rival Oregon State, but could not put one down before the final buzzer.

As a result, the Beavers won an improbable Civil War victory in a game they trailed by 20 points with as many minutes to play by the final count of 61-59 at Gill Coliseum.

The win for OSU (9-16, 2-12 Pac-10) was just its second in Pac-10 play, while UO's recent losing skid reached seven games and sent the Ducks (12-13, 3-11) under .500 overall for the first time this season.

Oregon State erased a 20-point halftime deficit in less than 15 minutes, battling all the way back to take the lead at 50-49 with 5:23 to play.

Amanda Johnson's deep three-pointer from the left wing grabbed the lead back for Oregon, and Jasmin Holliday's free throws made it 54-50 at the 3:51 mark.

But OSU again surged ahead by a point, 57-56, with two minutes left on a three-point play from El Sara Greer. It was a see-saw battle from there as another Johnson 3-ball pushed Oregon back on top by two.

Greer responded with a bucket in the paint and drew a foul, but couldn't convert the free throw, leaving the score knotted at 59-all with 1:14 to play.

That miss at the line – one of 13 on the night from the stripe for the Beavs - didn't matter in the end as free throws by Alexis Bostick with 57 seconds on the clock were the only made shots by either team for the rest of the game.

The Ducks missed their final four attempts from the floor after Johnson's clutch three, including the junior forward's game-winning attempt with six second to play and Deanna Weaver's put-back attempt off the offensive rebound with two ticks to play.

Johnson finished with team-highs of 18 points and nine boards, while going 4-of-8 from beyond the arc. Recent starting G/F Tatianna Thomas finished with 11 points and point guard Ariel Thomas dished out a game-high six assists.

Greer led all players with 21 points and 13 rebounds, and fellow post Earlysia Marchbanks had 17 points and a game-high six steals for Oregon State.

Oregon was 20 of 66 (30.3%) from the field, including 11 of 33 from beyond the arc, while OSU shot 22 of 60 (36.7%) overall.

The Beavers were 4 of 22 from three-point range and 13 of 26 from the line, but they attempted 16 more free throws than the visitors as the Ducks piled up 23 fouls compared to eight for OSU.

The Ducks shot just over 35 percent in the opening half, but that didn't stop them from building a 20-point lead going into the break at 36-16. UO made 8 of 21 three-pointers and capitalized on 13 OSU turnovers.

Johnson led all scorers with 10 points, and Tatianna Thomas chipped in nine in only 11 minutes due to three first-half fouls.

Despite trailing 12-7 midway through the half, Oregon's tempo appeared to become an issue for the home side as UO's run and gun game proved too much for the Beavers to cope with and led to a 29-4 run to end the half.

At one point during the spurt, the Ducks ran off 24 straight points, including eight by Johnson on a pair of straightaway three-pointers to go with a baseline jumper.

The Beavers responded in the second-half, starting with a 13-0 run of their own over the first 6:46 as the Ducks went ice cold from the field, missing their first eight attempts. Victoria Kenyon broke the string with a pair of free throws to make it 38-29.

Another 14-6 run by OSU brought them within one at 44-43 with 9:34 left, and it essentially became a brand new game.

NOTES: The Ducks had won three straight vs. Oregon State, including an 81-72 victory on Jan. 23 at Matthew Knight Arena … Johnson needs one steal to tie Vanessa Seldon (1990-92) for eighth at Oregon … Nia Jackson missed her fourth straight game after suffering an injury Feb. 3 at Washington … Entering the contest, Oregon had lost 9 of its last 10 games while Oregon State had dropped 11 out of 12.
