First pitch is scheduled for 3 p.m.

(Follow the game live here)

It’s the first outing of a double-header that will see the winner advance to face No. 3 seed USC on Sunday night. The Trojans are 2-0 in the double-elimination event and sit one win away from reaching the super regionals.

If the OSU-Saint Mary’s winner defeats USC in Sunday’s nightcap, the teams would meet again on Monday in a winner-take-all finale.

After suffering an opening-round upset against Saint Mary’s, the Beavers vowed to fight back and “do something special” … and they backed up the pledge in their first elimination game, defeating TCU 7-2 on Saturday to keep their season alive.

Freshman right-hander Dax Whitney was electric and the Beavers’ offense slugged four home runs in the win. Afterward, Saint Mary’s suffered a 6-4 defeat to USC, setting up today’s losers’ bracket rematch.

Here are details about the first game of Sunday’s double-header:

Probable starters: TBA

This and that: Neither team has announced its starting pitcher, but the Beavers are expected to go with sophomore Ethan Kleinschmit, who was their Sunday starter all season. The 6-foot-3 left-hander has been OSU’s most consistent starter this year, going 7-3 with a 3.84 ERA and 89 strikeouts in 72 2/3 innings. And Kleinschmit is coming off one of his best performances, a one-hit, seven-strikeout gem against Long Beach State in the regular-season finale. … Wilson Weber, Trent Caraway, AJ Singer and Tyce Peterson bashed home runs for OSU in Saturday’s elimination game. It was the fourth time this season the Beavers have hit four or more homers in a game and it pushed their season total to 89, tied for the second-highest single-season total with the 2023 club. The Beavers hit a school-record 118 in 2024. … Caraway has belted a home run in each of the first two games of the regional and in three of his last four games. The sophomore third baseman hit six during the regular season. … Gavin Turley enters the game with 179 RBIs in his career, tied with Michael Conforto for the most in program history. … The Gaels have been carried all season by the strength of their lineup — not their pitching — and the depth of their staff will be tested today. Saint Mary’s likely will start right-hander Lukas Sarantos, who is 3-0 with a 5.40 ERA this season. He’s made 15 appearances, including seven starts. … The Gaels’ staff ERA is 6.17.
