A first inning run for Oregon State was just the opening salvo, as the Beavers would tack on five in the second and another in the third to take a 7-0 lead after just three innings of play.
Reed recorded just eight outs and gave up just as many hits before leaving the game in the third.
"I left a couple pitches over the plate and they really punished me for it," Reed said. "It goes to show how well Tommy threw Friday, because I thought they came out and really swung the bats."
Five of the Beavers' first seven runs came off the bat of Michael Conforto. The left fielder knocked in a lead-off batter Tyler Smith in the first and added a grand slam in the second to push Oregon State to a seemingly insurmountable lead.
"Conforto is as advertised. We threw him the kitchen sink today and he hit everything," said Oregon head coach George Horton. Conforto finished 3-for-6 with 6 RBI.
The Oregon bullpen held the Beavers down until the eighth inning when Jimmie Sherfy entered and allowed four to score. Three runs were credited to Sherfy, who had four all season entering the game.
Oregon State scored their final run off of Jordan Spencer in the ninth.
"We got whipped," Horton said. "There's no question about it. We got out-pitched, out-defended, out-hit. I didn't like the personality that we tried to respond to that. Our reaction to the adversity was not spot on."
Despite the one-sided outcome, Oregon wasn't without their opportunities. Oregon loaded the bases the twice, but came up with just two runs for the game.
The first came in the second when J.J. Altobelli drove a ball to the warning track in center field for what appeared to be a three-run double. Instead, Oregon State center fielder laid out for an incredible inning-ending out.
"It was carrying up there for a while, so I thought he had chance. That was a big momentum changer. I think it's a 6-3 ball game at that point and you never know what can happen," Altobelli said.
Oregon placed two on in the fifth with one out, and brought the conference RBI leader Ryon Healy to the plate. But the slugger grounded into an inning-ending double-play.
Noticeably agitated, the first baseman tossed his bat into the air and slammed his helmet into the turf repeatedly.
"That kind of emotions crept out of me right there. I was embarrassed by that and that's definitely not the way the Ducks play the game," he said.
The win gave Oregon State (43-9, 23-4) complete control of their Pac-12 crown run with just three league games remaining. Oregon (42-12, 21-6) will have to fight off UCLA for second place.
"If things things go the way in the Pac-12 conference, like they probably will, it's a hard thing to say, but they're the best team in the conference. Sometimes you need to call it as you see it," Horton said.
The loss puts the Ducks' quest for a potential national seed in the College World Series in jeopardy.
"There's no disrespect to losing to one of the top-five teams in your ballpark," Horton said. "Our body of work speaks for itself. Our RPI is there," Horton said.
"We're going to get back to work. Nobody's going to think we don't have a chance to win a national championship, I can guarantee you that."
