OMAHA, Neb. — Oregon State reversed roles with Arizona State for six innings.

That was long enough for the Beavers, who built an 11-run lead and held off the power-laden Sun Devils 12-6 in Monday night's matchup of Pac-10 Conference rivals in the College World Series.

It was 12-1 and OSU outhit the Sun Devils 17-3 through six innings. But ASU almost made things interesting by batting around in the seventh inning, scoring four runs on three walks and three singles against four different OSU pitchers.

But that wasn't near enough in a game that took 3:34 to complete.

Mike Lissman drove in four runs by rapping three hits and homering for the second straight game. Chris Hopkins, Joey Wong and Jason Ogata added three hits each, and Jordan Lennerton homered in support of Beaver starter Mike Stutes (11-4).

"We needed a quality start from Mike against a quality club, and we got it," OSU coach Pat Casey said.

The Beavers (46-18) are the lone unbeatens in their four-team bracket and are idle until Wednesday when they face the winner of today's elimination game between ASU (49-14) and UC Irvine (45-16-1).

In a game that started 90 minutes later than scheduled because of the 13-inning elimination game won 5-4 by UC Irvine over Cal State Fullerton, the Beavers jumped to a 2-0 lead in the first inning. The rally featured singles by Hopkins, Darwin Barney, Lissman and Jason Ogata against Brian Flores (11-1), who was replaced by Josh Satow after the first inning.

"I was extremely happy we got it going early," Casey said.

The Sun Devils quickly struck back against Stutes, sandwiching two singles around a hit batter to make it 2-1 in the top of the second.

OSU made it 6-1 in the lower second with a two-out rally. Retherford singled, stole second and scored on Wong's double. Barney coaxed a walk and Lissman lined a 2-2 pitch for a three-run homer, his 10th of the season.

Lennerton's eighth homer made it 7-1 in the third, more than enough support for Stutes, the losing pitcher in Game 1 of an ASU series sweep last month in Corvallis. The Sun Devils beat Stutes 4-3, then followed with 3-0 and 8-0 victories in that series.

But it was no contest on this night as the Sun Devils managed only three hits, all singles, against Stutes, who struck out four and walked five in six-plus innings. Several balls that were hit hard were right at Beavers, and a budding rally in the second was limited to one run by a fine play at shortstop by Barney.

The Beavers added single runs in the fourth, helped by a throwing error on what should have been an inning-ending double play, and in the fifth on a double by Lonnie Lechelt and a single by Wong for a 9-1 lead. A run-scoring triple by Lechelt and two unearned runs in the sixth made it 12-1.

Stutes was pulled in the seventh after two walks and a single loaded the bases with none out.

"I guess I just ran out of gas," Stutes said, "so it was a good time to pull me."

Blake Keitzman relieved, and all three runners inherited by the freshman from Roseburg scored on singles by Raoul Torrez and Eric Sogard.

Mark Grbavak came on and issued a walk on four pitches before Joe Paterson became the fourth pitcher of the inning. Paterson, who pitched 22/3 innings in Saturday's 3-2 win over Fullerton, got out of the inning with a sacrifice fly and infield popup as the lead was trimmed to seven.

All told, the Beavers outhit ASU 18-7 as every OSU player except catcher Mitch Canham had at least one hit and six players had at least two.

The loss was the first for ASU since May 25 against rival Arizona.

"It's pretty clear we got punched in the mouth tonight," ASU coach Pat Murphy said. "I don't want to take anything away from Oregon State, but it's the worst we've played all year for six innings.

"We were just kind of shell-shocked. That hasn't happened to us, and we hadn't lost in a long time. That punch in the mouth was coming. But we're three games from playing in the championship series."

The Beavers are one victory from that status.
