OMAHA, Neb. — The dominance Oregon State has shown all season was on full display Monday night.

Bryce Fehmel limited LSU to two hits in eight innings, KJ Harrison hit the first College World Series grand slam at TD Ameritrade Park, and Oregon State beat the Tigers 13-1 for its 23rd straight win.

The Beavers (56-4), who matched the school-record win streak they set earlier this season, took control of Bracket 1. They don’t play again until Friday, and need one more win to advance to next week’s best-of-three finals.

“We just talked before the game about this is our time, this is our opportunity,” Oregon State coach Pat Casey said. “This is what we came here for. Let’s not miss that moment. So the guys played great.”

The matchup between the teams with the two longest active win streaks in the country was one of the most anticipated at the CWS in years. It turned out to be a dud. The 12-run margin tied the largest in a CWS game in the seven years it’s been played at TD Ameritrade.

LSU (49-18) had its 17-game win streak end with its most lopsided loss in Omaha since a 20-6 rout by Cal State Fullerton in 1994.

“It wasn’t what we expected or hoped for, obviously,” Tigers coach Paul Mainieri said. “Heck of a way for a 17-game winning streak to end. Right from the start things didn’t go well for us.”
