BATON ROUGE, La. (AP) — Jared Poche struck out seven and did not allow a run until the eighth inning, Kade Scivicque broke up a scoreless tie with a home run in the seventh, and LSU clinched its 17th College World Series appearance with a 6-3 victory over Louisiana-Lafayette on Sunday night.

Shortstop Alex Bregman, LSU’s top pro prospect, ended an 0-for-15 slump with a two-out, two-run single in the eighth, and Conner Hale added a two-run triple as the Tigers (53-10) swept their best-of-three super regional with the Ragin’ Cajuns (42-23) to remain unbeaten in the NCAA Tournament.

Poche (9-1) allowed five hits and walked one.

Louisiana-Lafayette starter Gunner Leger (6-5) appeared to be in complete control through 7 1/3 innings, having thrown only 70 pitches before Scivicque crushed his homer over the left-field bleachers.

Bregman’s first hit of the NCAA Tournament gave the Tigers a 3-0 lead, and Hale’s triple to right off of reliever Dylan Moore made it 5-0.

The Cajuns, playing as the home team in LSU’s Alex Box Stadium for Game 2 of the series, scored their first run of the game on a fielder’s choice with one out in the bottom of the eighth.

LSU added another run on Mark Laird’s run-scoring single to right center to make it 6-1 in the ninth.

Louisiana-Lafayette, which had used a five-run, ninth-inning rally to pull out its NCAA regional opener nine days earlier, plated two more runs in the ninth before LSU reliever Parker Bugg induced Blake Trahan’s game-ending pop-up to first. That sent LSU players streaming onto the field in celebration as they received what has become a fairly familiar send-off to Omaha from jubilant fans packing the stadium.
