BATON ROUGE, La. (AP) -- LSU ace Kevin Gausman allowed one run and no extra-base hits through eight innings, and the Tigers defeated Oregon State 7-1 on Saturday night in the winner's bracket of the NCAA tournament's Baton Rouge regional.
Gausman (11-1) threw a season-high 129 pitches -- 62 through the first three innings. He yielded seven hits and struck out three.
The victory means LSU (45-16) can advance to a super regional with a victory Sunday night over the winner of the afternoon's elimination game between Oregon State (39-19) and Louisiana-Monroe (32-29).
Austin Nola went 2 for 4 with an RBI single in LSU's two-run second and an RBI triple in the eighth. Ty Ross and Grant Dozar each had two hits and an RBI for LSU.
Beavers starter Dan Child (6-4) lasted 5 1/3 innings, allowing five runs on seven hits. Ryan Dunn drove in the Beavers' lone run in the third inning.
