OMAHA, Neb. — With a wave of his cap to the LSU fans, Alex Lange disappeared into the dugout after what very well could have been his last outing as a collegian.

It was one of his best, and most timely.

The Chicago Cubs’ first-round draft pick limited top-seeded Oregon State to two hits over 7 1/3 innings in a performance Friday that carried the Tigers to a 3-1 victory and ended the Beavers’ 23-game winning streak.

It also set up a winner-take-all Bracket 1 final at the College World Series on Saturday, with the winner going to the best-of-three finals beginning Monday.

Lange (10-5) won a CWS elimination game for the second time in his career, and he said his experience pitching so many important games at home in Baton Rouge, Louisiana, prepared him.

“I had a sense of calmness about me this morning when I woke up, and getting to the yard. I was expecting to be amped up and juiced up,” Lange said. “I was calm and relaxed. I think that goes back to pitching in Alex Box Stadium in front of 12,000 people every Friday night. It wasn’t a big shocker or big difference. This is why I came to LSU, to play in these big games. And keeping your team in the ballgame and keeping the season alive is pretty awesome.”

The Tigers (51-18) avenged a 13-1 loss to the Beavers (56-5) on Monday and became the first team to knock them off since Southern California on April 29.

They did all of their scoring against national wins leader Jake Thompson (14-1).
