FORT WORTH -- Oregon State's string of winning nine straight elimination games in NCAA baseball tournament play trumped Texas A&M's run of avoiding elimination in six consecutive regional contests.

The 2006 and '07 national champions dumped six runs on the Aggies in the first inning Sunday and went on to win 13-5, earning another shot at TCU in the Fort Worth Regional.

A&M finished the season, one in which they were the preseason No. 1 in one polls, at 37-24.

"Just take it one pitch at a time, one inning," Oregon State coach Pat Casey said. "We really focused on being tough, trying to not let somebody take something away from you, the passion, desire to not being eliminated."

The Aggies had done a good job of being tough and playing with passion over the past few years and continued that through the first two days at Lupton Stadium. It may have been too much to ask for one more time, especially after having to climb out of another deep hole.

A&M led only one inning out of 29 in the tournament -- the final one on Saturday against Wright State.

"My disappointment is not in our guys, it's for our guys. They gave it everything," A&M coach Rob Childress said. "The only reason you have disappointment is because of expectations and nobody's expectations for this program are higher than the people within it, and that's the coaches and players."

The Beavers held all the cards after the opening frame, getting their leadoff hitter on board on a third-strike passed ball.

Adalberto Santos followed with a single up the middle, Koa Kahalehoe showed bunt, then swung away and slapped a shot toward A&M shortstop Adam Smith, who was covering second and was only able to knock the ball down.

Smith then saved one run, momentarily, by getting a glove on Ortiz's infield hit up the middle that did plate Michael Miller.

Jarred Norris followed with a double that went off the left-field fence, scoring Santos and Kahalehoe.

A&M then traded an out for a run on Steven Romero's grounder to third. Clayton Ehlert (5-2) got John Wallace to fly out, but the bottom two hitters in OSU's lineup -- Joey Wong and John Tommasini -- both doubled to drive in the fifth and sixth runs of the inning.

"Disappointing game to say the least," Childress said. "[They had] bases loaded after a strikeout and two infield hits and then they got big hits, and we're playing catch-up from the word go."

The deficit grew insurmountable from there. Ehlert was unable to make it out of the second inning after Ryan Ortiz supplemented Oregon State's small-ball and timely hitting with a towering homer to left.

Ortiz's homer was the seventh hit in 13 plate appearances for the Beavers up to that point. They didn't get a hit until the sixth inning of their 13-1 loss to TCU on Saturday.

"Well, last night we were sitting here talking about how we couldn't hit," Casey said.

Kahalehoe was 5 for 5 on Sunday after going 3 for 4 on Friday against the Aggies. He came in hitting .215 and was moved up to the No. 3 hole "on a hunch," Casey said. Ortiz, in his customary cleanup spot, went 4 for 6.

Oregon State added a run in the third and made it a double digit-lead at 11-0 with three more in the fifth.

By that time, Childress was on his fifth pitcher.

Meanwhile, Beaver junior right-hander Jorge Reyes was rolling along, showing the form that made him Most Outstanding Player in the 2007 College World Series.

"The guys had been talking about going all-out and our backs are against the wall," Reyes said. "I told myself, 'Go as hard as you can as long as you can,' and it worked out."

Reyes (6-2) threw a complete game, giving up 10 hits and three earned runs.

One of the hits was a long home run by Joe Patterson in the sixth. It was his second of the tournament and 12th of the season.

A&M got to Reyes for two runs in the eighth on singles by Luke Anders and Patterson and a two-run double by Caleb Shofner, who finished the tourney 7 for 12 with two homers and six RBIs.

Oregon State made two errors in the ninth, and Anders followed with an RBI ground out before Kyle Colligan got an RBI single in his final at-bat as an Aggie.
