OKLAHOMA CITY — On a night filled with career-highs for Lyndsey Grein in the circle, it was the actions Oregon’s ace took when she wasn’t pitching that may have been the biggest difference in her latest masterpiece performance, which kept the Ducks alive at the Women’s College World Series.

With Rylee McCoy committing two early errors in her first game back at first base since taking a line drive to the face in the Eugene Regional final against Stanford, it was Grein who consoled the All-American freshman, who was later moved to designated player.

After getting out of a two-on, two-out jam in the top of the tenth, it was Grein who spoke up in Oregon’s huddle even after she threw 94 strikes out of 144 pitches over 9 1/3 innings — all career-highs for the junior right-hander.

Grein held Ole Miss 2 for 13 with runners in scoring position and though she surrendered the game-tying two-run single in the seventh, the All-American buckled down and finished the gutsiest performance of her career. She silenced the Rebels throughout extra innings long enough for the Ducks to finally break through once more in a 6-5 win in 10 innings decided on a walk-off walk by Kedre Luschar after Friday night turned to Saturday morning at Devon Park.

“I knew my teammates had my back regardless,” Grein said. “I knew before we got here we were going to pull it off. We didn’t know what it would look like, but the Ducks were going to leave with a win today.

“I told my teammates as long as there’s innings and we have outs to spare, I will stay here until 8:30 the next — or today, and however long it was going to take for us to win. But today wasn’t the day that Version 7 ends their season.”

Grein left with with Oregon leading 2-1 with two outs and a runner on third in the fifth, then Ole Miss tied it on a single by Persy Llamas off Staci Chambers. Grein later reentered with two on and one out in the sixth, one of multiple jams she got out of unscathed, and did not leave the circle again.

Grein’s performance actually improved after reentering, despite the high leverage situations she was in.

She notched four of her seven strikeouts after returning to the circle and threw 46 strikes on 64 pitches compared to 48 out of her first 80. She threw first pitch strikes to 14 of the final 21 Ole Miss batters she faced compared to 10 of the first 21.

“I think they did a good job pitch calling because they went back down and mixed in some different off speeds in some of those counts, whether they led with it or finished with it, just to keep us off balance,” Ole Miss coach Jame Trachsel said. “Good pitcher, had good command today, up and down and mixed speeds and could throw it on different counts. Could throw it for a strike or expand the zone. It was a tough puzzle to crack.”

It was the most pitches thrown by an Oregon pitcher since Jordan Dail’s 145 against Utah on May 3, 2019, when UO literally had no other pitchers on its roster.

While not extremely outrageous volume in college softball, Oregon coach Melyssa Lombardi avoids overworking her pitchers and looks to avoid topping 120 pitches in a game.

Made aware Grein was one shy of the high pitch count mark of her tenure, Lombardi smiled.

“Lyndsey is just a straight-up competitor on the mound,” Lombardi said. “There’s no way she’s coming out of that game. There’s no way. She’s going to finish it.

“At Oregon, we talk about it all starts in the weight room. And the reason why Lyndsey was able to finish that game is because it all starts in the weight room. What she’s done with (strength coach Kaelin Jackson) has given her the strength, the endurance she needs to start a game like that and come out and reenter it and finish it and get better as the game went on. She got better as the game went on.”

It was performances like Grein’s that Oregon has so sorely been missing from the circle since All-American Brooke Yanez, who missed the 2022 season due to injury and transferred to UCLA in 2023.

Getting out of one jam after another — two on, no outs; two on, one out; runner on second, one out; bases loaded, one out; first and second, one out; first and second, two outs — against top competition on the sport’s biggest stage is what will make Grein’s outing live in lore no matter how Oregon’s season ends.

“It was just a no-way mentality,” Grein said. “I think one of the things that motivates me is when I glance up and look at my teammates, and that gets me really motivated, just to do it for them. ”

Grein allowed five runs, four earned, on eight hits and three walks, but those figures will be lost to history compared to the ultimate result as Oregon (54-9) advances to play the loser of Texas and Oklahoma in an elimination game on Sunday (4 p.m., ESPN2).

“I put her up against any hitter in this country and she’s going to win, and I just know it,” Luschar said. “I trust her, I believe in her, and she’s so awesome to play behind.”
