Omaha, Neb. ? Oregon State became the first team in a decade to repeat as College World Series champion, completing a dominant run through the tournament with a 9-3 victory over North Carolina on Sunday night.

The Beavers (49-18) won all five of their CWS games, including a sweep of the Tar Heels in the best-of-three finals, and trailed for only one of 45 innings they played in Omaha.

North Carolina was runner-up for the second straight year after the first CWS finals rematch since Arizona State and USC met in 1973. Oregon State is the first back-to-back champion since LSU in 1996-97 and the fifth overall.

Darwin Barney’s two-run homer gave the Beavers the lead in the second inning of the decisive game. Jordan Lennerton hit his second homer in two nights, a two-run shot in the eighth.

The Tar Heels (57-16) didn’t get much going against Oregon State’s steady pitching and solid defense, and were shut down whenever they appeared on the verge of a big inning.

Mark Grbavac and Joe Paterson combined to retire the last seven North Carolina batters. Paterson got a called third strike against pinch-hitter Kyle Shelton to end the game and send the Beavers sprinting out of their dugout for the celebratory pile.

“It’s crazy. It’s just crazy,” Oregon State coach Pat Casey said. “I just felt like we were going to win. There is something in that dugout.”

The Beavers, who were nearly left out of the 64-team national tournament field after struggling in the Pacific-10 Conference, finished the season with 10 straight wins and became the first to win four CWS games by six runs or more.

“When we got here, we were excited to get in that dugout and in that locker room,” Barney said. “We feel very comfortable in there. This is home, baby. This is Omaha.”

The Beavers knocked out North Carolina starter Luke Putkonen (8-2) in the second inning after Barney lined a pitch over the left-field wall. Another run scored on third baseman Chad Flack’s throwing error.

Tar Heels coach Mike Fox made a surprise move by bringing in closer Andrew Carignan, whose appearance in the second inning was his earliest in two years.

Not even Carignan, who allowed no runs and only one hit in 61â3 CWS innings before Sunday, could stop the Beavers. Singles by Santschi in the third and John Wallace in the fifth stretched the lead to 5-2.

Dustin Ackley hit his second homer of the CWS and 10th of the season to pull North Carolina to 5-3, but Scott Santschi’s third RBI single and Chris Hopkins’ infield hit made it 7-3 in the seventh.
