OKLAHOMA CITY (AP) — Stanford’s NiJaree Canady outlasted Washington’s Ruby Meylan in a battle of Pac-12 freshman pitchers to push the Cardinal into the national semifinals.

Canady threw a one-hitter, and No. 9 seed Stanford beat No. 7 Washington 1-0 on Sunday in a Women’s College World Series elimination game.

Canady, the National Fastpitch Coaches Association’s Freshman of the Year, struck out nine and didn’t allow a walk. She credited her coach for helping her stay relaxed.

“Coach (Jessica) Allister always talks about slowing the game down, especially in this atmosphere, just trying to slow the game down,” Canady said. “I try to take a lot of deep breaths and just throw each pitch the best I can.”

Meylan gave up four hits, struck out five and walked one. No earned runs were scored in the game.

“It’s an old fashioned pitchers’ duel that we don’t see much of, but it was going to be whoever bent first,” Allister said.

Kylie Chung’s RBI single in the sixth scored Taylor Gindlesperger for the game’s only run. It was unearned because it came after a throwing error with two outs.

“I feel like our at-bats got better throughout the game,” Chung said. “I feel like we all had confidence, if we just kept sticking with it, that something was going to fall.”

Chung, a sophomore left fielder, was only starting for the 15th time this season.

“I couldn’t be more proud of Kylie and just her stick-to-itiveness,” Allister said. “It’s easy to think, I’m never really going to hit, but she continued to prepare, continued to prepare, and to see her get paid off now, it’s fun.”

Washington (44-15) had an opportunity in the sixth after two errors by Stanford put runners on first and third with two outs, but a pop-up to center ended the threat.

It will be Stanford’s program’s third trip to the semifinals and first since 2004. The Cardinal got there by scoring three runs in three games.

Stanford (47-14) will play two-time defending champion Oklahoma (58-1) on Monday. It is a double-elimination bracket and Oklahoma is unbeaten while Stanford has a loss, so the Cardinal will need to win twice on Monday while Oklahoma will need to win just once to advance to the best-of-three championship series.

Oklahoma is on a 50-game win streak and leads the nation in scoring, batting average, earned run average and fielding percentage. The Sooners defeated Stanford 2-0 on Thursday.

Stanford had a chance to score in the third against Washington on Sunday. Gindlesperger singled up the middle with Ellee Eck on second, but Washington centerfielder Brooklyn Carter threw Eck out at home to end the inning.

Washington nearly didn’t make it this far. The Huskies scored seven runs in the seventh to beat McNeese State 7-6 in the decisive regional game, then beat a strong Louisiana-Lafayette squad to qualify for the World Series.

Meylan said Washington fans have a lot to look forward to.

“The future is really, really bright,” she said. “We have some amazing, amazing girls, and I know we have a really good class coming in.”

Tennessee 3, Oklahoma State 1

OKLAHOMA CITY (AP) — Tennessee moved past a lopsided loss and focused on the opportunity at hand.

Ashley Rogers threw a complete game, and the fourth-seeded Lady Vols defeated No. 6 Oklahoma State 3-1 on Sunday to qualify for the Women’s College World Series semifinals.

Tennessee’s ace gave up one run on four hits and struck out four. She returned to the circle after not playing in a 9-0 loss to Oklahoma on Saturday that put the Lady Vols on the brink of elimination.

“We don’t think that was us on the field yesterday,” Rogers said. “Just knowing who we are as a team and just playing Tennessee softball and just flushing it, turning the page — it’s a new day, it’s a new game.”

Rogers threw 136 pitches.

“I feel like I’m pretty conditioned to throw that,” she said. “I’ve probably thrown over 100 pitches most of my games. Trusting my preparation, trusting the defense, continue to fight and fight every single pitch.”

Tennessee (51-9) advanced to play No. 3 Florida State (57-9) on Monday. It is the Lady Vols’ best World Series showing since finishing as runner-up to Oklahoma in 2013.

It is a double-elimination bracket, and Florida State is unbeaten while Tennessee has a loss, so the Lady Vols will need to win twice on Monday while Florida State will need to win just once to advance to the best-of-three championship series.

Rogers’ effort allowed the Lady Vols to save Payton Gottshall for Monday. Gottshall has a 16-1 record with a 1.57 earned run average.

Oklahoma State (47-16) made its fourth straight World Series appearance but hasn’t reached the championship series. The Cowgirls reached the semifinals last year.

“We’re just going to keep kicking the shins of our opponents, and we’ll eventually break this door down, and we’ll look back to teams like this,” Oklahoma State coach Kenny Gajewski said.

No. 1 Oklahoma (57-1) will play No. 9 Stanford (47-14) in the other semifinal. Stanford will need to win twice, while the two-time defending champion Sooners will need one victory to move on.

Kiki Milloy got the Lady Vols going against Oklahoma State starter Kelly Maxwell when she walked, stole second and scored on a double by Zaida Puni. Rylie West’s RBI single made it 2-0, and Maxwell was replaced.

Oklahoma State threatened in the fourth but failed to score. Tallen Edwards doubled, but Tennessee second baseman Destiny Rodriguez threw Micaela Wark out at home to end the inning.

In the fifth, Puni got on with an error, then scored on a throwing error to make it 3-0.

Morgan Wynne cranked a solo shot just inside the left foul pole in the sixth to get Oklahoma State on the board, but that’s all the Cowgirls could produce.

Maxwell took the loss for the Cowgirls. Lexi Kilfoyl did not allow a hit in 3 2/3 innings of relief.

Oklahoma State lost 11 of 13 before the NCAA Tournament but went undefeated through regionals and super regionals, allowing just three runs in five games to qualify for the World Series.

“It was mainly people on the outside who doubted us, and I think we stayed calm and the coaches helped us stay calm within each other,” Kilfoyl said. “We needed to look at the past and see what we’ve done and kind of take that and look at all the good stuff and use that to our advantage.”
