CORVALLIS, Ore. — Sixteen teams took off-ramps from the road to Omaha yesterday. But Hawai'i hasn't seen its exit yet.

Behind the stellar pitching of left-hander Ian Harrington, the Rainbows beat Wright State of Dayton, Ohio, 5-3, in an elimination game of the Corvallis Regional at Goss Stadium.

"I'm happy for our kids and happy for our coaches to get that first regional win in a while for the University of Hawai'i," UH coach Mike Trapasso said. "Now, we just have to go to work tomorrow."

The Rainbows kept their dreams of playing the College World Series in Omaha, Neb. They meet Kansas for the second time in the double-elimination regional at 10 a.m., Hawai'i time today. Host Oregon State defeated the Jayhawks, 11-3, yesterday.

The Raiders (32-37) became the first victims of this regional.

"I didn't want this to be the last game I coached them," Wright State coach Rob Cooper said.

Harrington (9-3) won his fifth consecutive decision with his third complete game, allowing three runs and six hits with three strikeouts.

"Ian Harrington controlled the game right out of the gate," Trapasso said. "He gave us what we really needed to have with our pitching depleted after Steven Wright's illness and going to the bullpen early (in Friday's 9-6 loss to Kansas). He gave us a complete game, saved our bullpen."

The Rainbows (44-16) burned 4 2/3 innings of relief on Friday after starter Justin Costi lasted just 3 1/3 innings.

Harrington's two-seam fastball worked best, but his usually reliable changeup abandoned him.

"I left it up a lot and one of them was hit over the fence," said Harrington in reference to Aaron Garcia's two-run home run to left in the ninth inning that cut the Raiders' deficit to 5-3. "I went other routes when that wasn't going well."

Harrington sailed through six innings. He didn't allow a hit until Justin Wilson led off the fifth with a line single to center. But Harrington stranded him.

The Raiders did not have more than one runner reach until the seventh. Consecutive singles by Garcia and Amin Abusaleh put runners at the corners. But third baseman Justin Frash dove into the hole to stop Wilson's grounder to turn a double play that allowed the Raiders' first run.

"Frash made a great play," Harrington said.

Trapasso said he had closer Darrell Fisherbaugh ready from the seventh inning. Hawai'i led 5-0 entering that frame.

"We were fortunate in that we had a good cushion that allowed us to stay with Ian," Trapasso said. "Really, he had only a couple innings where he was leaving the ball up. We had Fisherbaugh ready from the seventh inning on. He was prepared to get hot."

Harrington's 91 pitches was the fewest thrown in UH's seven complete games. That beat his previous low of 96 he used in a complete-game win against Sacramento State in the home finale on April 30.

The Rainbows started building support for Harrington in the third inning against Wright State starter Erich Schanz (6-4), who was charged with all five runs on nine hits and two walks with seven strikeouts in 5 2/3 innings.

Robbie Wilder led off with a walk. Derek DuPree then hit a sinking liner to center for a triple that center fielder John Koplichack tried to shoe-string, but instead the ball got under his glove and rolled behind him, easily scoring Wilder. Frash's sacrifice fly to left made it 2-0.

Asked if he would play the liner the same way Koplichack did, outfielder DuPree said he would.

"But I wouldn't have missed it," said the usually reserved DuPree, drawing laughter at the press conference.

Hawai'i added two more in the fifth. DuPree led off with a single to left-center and took third on Frash's single to right. Frash took second on the throw to third. Luis Avila's sacrifice fly to right scored DuPree and moved Frash to third. Frash scored on Matt Inouye's ground double to left to make it 4-0.

The Rainbows, beaten by four home runs by Kansas on Friday, got their first one of the regional when Wilder drilled a 3-1 fastball over the right field fence to make it 5-0 in the sixth inning.

"The wind wasn't blowing across like yesterday or that ball might not have gone out," said Wilder of his second homer of the season.

Left-hander Mark Rodrigues (4-2) is scheduled to get the start today for the Rainbows against Kansas (43-24). The Jayhawks will start right-hander Ricky Fairchild (6-6).

The winner of today's Kansas-Hawai'i game plays again at 3 p.m. today against undefeated Oregon State. An Oregon State loss would force a playoff tomorrow with the winner advancing to the Super Regional against the winner of the Austin, Texas, regional.

NO. 5 OREGON STATE 11, NO. 22 KANSAS 3

Chris Kunda drove in five runs with his first two home runs of the season to carry the top-seeded Beavers (41-14) into today's championship. Kunda hit a three-run home run in a seven-run second inning when the Beavers sent 10 batters to the plate. He then whacked a two-run home run in the fourth to increase OSU's lead to 9-0 against KU starter Sean Land (5-7).

Land allowed nine runs (eight earned) on seven hits and two walks with two strikeouts in 3 1/3 innings for the Jayhawks. Oregon State's Jonah Nickerson (10-4) allowed three runs on three hits — home runs to Brock Simpson in the fifth that spoiled his shutout and no-hit bid and to Ryne Price, as well as a double to Matt Baty. He walked four and struck out eight.
