The Oregon State Beavers are going to the finals of the conference tournament for the first time since 1988.
The Beavers (16-12) survived a late rally from its heated rival, the Oregon Ducks (20-6), in the semifinals of the Pac-12 Tournament, 75-64, behind 16 points from Ethan Thompson, who made a career-high-tying five three-pointers. Heading into Friday, Thompson had shot 26% from three for the season.
Oregon State led by as many as 19 points, but Oregon ended up going a 15-3 run to cut it to five points. Then, Jarod Lucas hit the shot of the night.
After pulling off back-to-back upsets in Las Vegas, the Beavers, who were chosen to finish last in the conference in the preseason media poll, are one win away from making the NCAA Tournament for the first time since 2016 and only the second time since 1990.
They will play the winner of second-seeded USC and third-seeded Colorado.
Oregon State defeated the Ducks just five days after Oregon celebrated a second consecutive Pac-12 regular-season championship in the locker room of Gill Coliseum.
Oregon State held the Pac-12's most prolific three-point shooting team to just 24% from beyond the three-point line.
Meanwhile, the Oregon Ducks will await to learn its at-large seeding in the NCAA Tournament to be announced Sunday afternoon. Friday's defeat was the first time Oregon lost a Pac-12 Tournament game since March 9, 2018, that's 1,099 days.
The Pac-12 Tournament Final is set to tipoff Saturday, March 13th at 7:30 p.m. PT on ESPN.
