CORVALLIS, Ore. (AP) — Zach Reichle hit a key 3-pointer down the stretch and Oregon State overcame a 10-point deficit in the second half to beat No. 14 Oregon 63-53 on Saturday night.

It was the third consecutive win for Oregon State in the 353rd edition of the Civil War, which is the most contested rivalry in college basketball.

Ethan Thompson, whose dunk with three seconds left punctuated the victory before a sellout crowd at Gill Coliseum, led the Beavers with 15 points. Kylor Kelley added 14 points, seven rebounds and two blocks, and leading scorer Tres Tinkle had 13 points.

Payton Pritchard led the Ducks (18-6, 7-4) with 16 points, but the Pac-12’s leading scorer was only 7 of 21 from the field.

Reichle’s fast-break dunk put the Beavers on top 50-48 at the 2:52 mark.

Tinkle hit both ends of the bonus to give Oregon State a four-point advantage, and Pritchard’s layup over the outstretched hand of 7-footer Kelley cut the lead to 52-50 with 2:06 left.

Reichle’s 3-pointer gave the Beavers a 55-50 lead at the 1:17 mark.

An 8-0 Oregon run early in the second half culminated by Pritchard’s basket in the lane gave the Ducks their biggest lead at 40-30.

Back came the Beavers.

Reichle’s 3-pointer ended the Ducks’ run, and Tinkle’s six straight points cut the lead to 42-40.

Kelley’s alley-oop dunk on an assist from Tinkle tied the game at 42-all with 11:10 remaining.

Thompson’s fadeaway jumper in the lane gave the Beavers their first lead since late in the first half at 44-42 and extended a 10-0 run.

Pritchard’s layup tied the game at 44-all with 6:06 remaining and was Oregon’s first field goal in more than eight minutes.

Oregon closed the first half on a 7-0 run and led 32-28 at the break. The first half was close the entire way with Oregon State holding the largest lead of five points.
