CORVALLIS — Kyle Nobach drilled a three-run home in the sixth inning Friday, and Bryce Fehmel shut down the UCLA offense as second-ranked Oregon State topped the Bruins, 4-1, in a Pac-12 Conference baseball game at Goss Stadium.

The game was scoreless until the bottom of the sixth inning when the Beavers loaded the bases with one out on walks to Adley Rutschman and Trevor Larnach before Michael Gretler was hit by a pitch.

Tyler Malone then grounded out to the pitcher to score Rutschman before Nobach launched his homer to left field.

Nobach and Zak Taylor had two hits apiece for the Beavers (44-9, 20-8 Pac-12), who were held to five hits. Oregon State pulled within one-half game of Stanford (43-10, 21-8) for the conference lead.

That was more than enough support for Fehmel, who allowed three singles, struck out five and walked two in 6 1/3 innings. He allowed the Bruins' only run in the seventh inning.

Brandon Eisert got the final out of the top of the seventh inning and Kevin Abel pitched the final two innings for his first save of the season for the Beavers and had four strikeouts.

UCLA (35-19. 18-11) pitcher Zach Pettway allowed three hits and three runs after holding Oregon State scoreless for the first five innings.
