CORVALLIS — Oregon State’s hopes kept dying at the outfield wall.

Beau Philip nearly gave the Beavers a lead in the fifth inning before his fly ball was caught by Creighton right fielder Will Robertson as he ran into the wall for the third out.

Joe Casey almost tied the game in the sixth inning with a fly ball to left that Parker Upton caught to end the inning as he leaped at the wall.

Adley Rutschman’s final at-bat for the Beavers to lead off the eighth fell about one foot short of a perfect ending when Will Hanafan went to the warning track in center field before catching the ball.

The Bluejays (39-12) did not need to rely on the long ball after Isaac Collins put them ahead with a solo home run in the third inning to kick off a 4-1 victory over Oregon State in an elimination game at the NCAA’s Corvallis Regional on Saturday afternoon in front of 3,402 at Goss Stadium. Creighton found a few openings in OSU’s defense for nine hits and took advantage of three errors to move around the bases.

“We stung a couple balls to the track and they had a few bloops that fell in and got them going, but you can’t complain too much about that,” OSU senior first baseman Zak Taylor said.

Oregon State lost on consecutive days to become the first of the tournament’s 16 host schools to be eliminated in the regional round while assuring that the College World Series will crown a new champion this year. The Beavers finished the season 36-20-1.

“Our goal every year is a national championship, nothing else,” Taylor said. “We expected to win three games and play a Super Regional next week, but that’s not how it goes all the time.”

Cincinnati earned the fourth seed in the regional by winning four straight games at the American Athletic Conference tournament to get over .500 at 30-29 before it beat the Beavers 7-6 on Friday night. Creighton lost 6-0 to Michigan on Friday before bouncing back to eliminate Oregon State.

Oregon State finished off its late-season slide by losing for the 10th time in 15 games after rising to No. 4 in the country in April.

“It was a matter of us not playing good baseball, that’s the bottom line,” said interim coach Pat Bailey.

After Collins homered to open the third inning off starter Grant Gambrell, Oregon State committed two errors that helped two more runs score in the inning.

Jake Holton hit a one-out single and Robertson was hit by a pitch before Rutschman made a wild pickoff attempt that sent Holton to third base. Jack Strunc singled to center to score Holton before Kyler McMahan bobbled the ball twice for an error that allowed Robertson to score on the play and put the Bluejays ahead 3-0.

Oregon State got a run off Creighton starter Evan Johnson in the bottom of the fourth after Philip walked with one out. Taylor hit a double and George Mendazona walked to load the bases before Andy Armstrong hit a sacrifice fly.

Alex McGarry hit a two-out single in the fifth and Rutschman was intentionally walked before Philip’s fly ball was tracked down by Robertson.

Taylor walked to open the sixth before Casey hit a fly ball that Upton caught to end the inning.

Creighton added another unearned run in the seventh after Robertson hit a soft liner to left for a double before Strunc hit a pop fly that dropped for a single as Robertson reached third. OSU reliever Dylan Pearce made a pickoff attempt that Mendazona could not handle at third base for an error that allowed Robertson to score.

Rutschman, the projected No. 1 pick in Monday’s Major League Baseball draft, received a standing ovation before his final at-bat in the eighth inning when he flied out to deep center field.

Casey walked with one out in the ninth before Jake Dukart hit a grounder to Collins at second base for what appeared to be a game-ending double play, but Collins bobbled the ball as Oregon State got runners on first and second base. One day after homering, Tyler Malone stepped to the plate as the potential tying run, but he hit the first pitch to Collins and he started a double play that kept the Bluejays alive to play Sunday.
