LOS ANGELES -- The matchup between Oregon State's Josh Osich and UCLA's Trevor Bauer was expected to be a pitcher's duel as the No. 3 Beavers and No. 24 Bruins met at Jackie Robinson Stadium.

Osich took it one step further.

The left-hander threw the fourth no-hitter in Oregon State baseball history as the Beavers defeated the Bruins 2-0 in front of 1,221 fans Saturday afternoon.

The complete-game no-hitter is the Beavers' first since 1947, when Fred Gallagher no-hit Montana. It is the first by a Pac-10 pitcher against a conference opponent since Stanford's Jason Middlebrook no-hit UCLA in 1994.

And it came in a game that sent the Beavers to a 2-0 series victory against the Bruins. Oregon State goes for the sweep on Sunday.

"Everything went the right way," Osich said. "It was an unbelievable game to be a part of. Parker (Berberet) did a great job behind the plate and the defense behind me was outstanding. They picked me up when they needed to and overall it was just a great game."

"I'm very proud of Josh," Oregon State head coach Pat Casey said. "He was spot on, and his defense played incredibly well. This was an all around great game and it was something special to be a part of."

Osich ended the game with 13 strikeouts, a career-best, and threw 121 pitches in the process. His only blemish came in the fourth when he issued a 3-2, two-out walk to Dean Espy, the third batter in UCLA's lineup. But Osich got the next batter to fly out to center.

The complete-game effort was the first of his career and he improved to 6-1 this season.

The Beavers managed just four hits of their own against Bauer, who went the full nine innings but dropped to 8-2 on the year. He struck out 15 and walked two, and was touched for just two runs in the sixth inning.

That's all Osich needed.

Ryan Barnes drew a one-out walk in the sixth, then moved to third when Jared Norris singled to right with two outs.

That brought up Kavin Keyes, who fouled off a couple 0-2 pitches before hitting a shot to the right-center gap that scored Barnes and Norris and gave Osich the lead.

The no-hitter is the Beavers' first since Mike Stutes, Josh Keller, Mark Grbavac and Jorge Reyes combined to no-hit Hawaii-Hilo in 2007. Cleve Benson, Eric Selberg and Jack Humphrey combined to no-hit Portland in 1967.

The win put the Beavers at 32-8 on the year and 12-2 in Pac-10 play. UCLA fell to 22-16 overall and 10-7 in the Pac-10.
