The win sends the Beavers (47-18) into the best-of-three championship series starting Saturday. They will play the winner of Thursday's Rice-North Carolina game for the title.

Turpen (10-1) turned in the third straight strong performance by an Oregon State starter, not allowing a hit after the fourth inning. Joe Paterson pitched a perfect ninth.

The route to the championship series was much smoother this year. In 2006, the Beavers lost their CWS opener to Miami 11-1, then staved off elimination for four straight games to reach the finals.

Mitch Canham hit a two-run homer, Darwin Barney had two RBI singles and John Wallace added a run-scoring triple for the Beavers, who scored four unearned runs in the third inning.

OSU has won 11 of 13 games since a May swoon when the Beavers lost seven of nine, jeopardizing their hopes of returning to the tournament.

It was a disappointing finish for the Anteaters (47-17-1), who reinstated their baseball program in 2002 and were making their first CWS appearance.

The Anteaters captured the hearts of local fans by rebounding from an opening loss to Arizona State to win extra-inning games against Cal State Fullerton and Arizona State in their final at-bats.

The 13-inning win over Fullerton took 5 hours, 40 minutes, the longest game in CWS history. The 10-inning win over ASU came after the Anteaters rallied from four runs down in the eighth to win in their last at-bat for the third time in four games.

There would be no magic against Oregon State.
