OKLAHOMA CITY >> A few weeks ago, it looked like the door was wide open for a team other than Oklahoma to win the Women’s College World Series.

While this season’s WCWS, which begins Thursday in Oklahoma City, features several teams capable of winning the title, the Sooners are looking more and more like the favorites they were thought to be for much of the season.

Last year, the Sooners became just the second program to win three consecutive WCWS titles.

Now, they’ll try to become the first to win four consecutive.

“It would be easy to say, ‘We’ve had enough. This is hard work and we’ve had enough,’” Oklahoma coach Patty Gasso said. “But they’re elite athletes. Whether they want to or not, they grind, they work hard. Their best is always on the biggest platform.”

The Sooners enter the event on a nine-game winning streak including sweeping through both regional and super regionals.

They’ll open the WCWS against Duke, the only team in the field who is making its first appearance.

Duke softball, which is in just its eighth year of existence, opened the season with a 3-0 loss to the Sooners.

“We just want to be the grittiest and toughest team in the field,” Blue Devils coach Marissa Young said.

UCLA is in the WCWS for an NCAA-record 32nd time, back in the field after missing last year’s world series for the first time since 2014.

The Bruins struggled early in the season but turned a corner and enter the WCWS on a 13-game winning streak.

“I believe we’re battle-tested,” UCLA coach Kelly Inouye-Perez said. “There was a lot of emotion and frustration because that what sports does.”

The Bruins open the tournament against No. 14 Alabama, the lowest-seeded team of eight in the field.

However, Alabama is third among WCWS teams in pitching with a 1.89 team ERA.

“We preach the defense and the pitching stays constant,” Alabama coach Patrick Murphy said. “If we can scratch a run, we’re going to win. They’ve basically done that all year.”

Texas is the No. 1 overall seed after winning the Big 12 — the first team other than Oklahoma to win the league’s regular-season crown since 2011 — though the Longhorns fell to the Sooners 5-1 in the Big 12 Tournament championship game on May 11 in the same park where the WCWS is held.

The Longhorns went down to the wire in the super regional, battling back from a loss to Texas A&M in the opener to beat the Aggies in back-to-back games to advance to the WCWS for the second time in three seasons.

“I think that’s exactly what we needed going into this week,” Texas sophomore Reese Atwood said. “It’s definitely going to be hard. That series prepared us. It was a fight every single inning.”

Texas will take on Stanford in the first round.

The teams split two games this season.

Atwood and Stanford pitcher NiJaree Canady were two of the three finalists for USA Softball Collegiate Player of the year, with Canady winning the award.

Canady burst onto the scene as a freshman in last year’s WCWS, with four strong outings.

Canady’s changeup has elevated her game this season.

“When you have the capability to throw with this speed and movement that NiJaree does, batters are going to begin to cheat and try to get going a little bit sooner,” Stanford coach Jessica Allister said.

The final game of the day features a pair of former college teammates going head-to-head as head coaches, with Oklahoma State’s Kenny Gajewski and Florida’s Tim Walton facing off.

The two were teammates on Oklahoma’s 1994 national championship baseball team. Gajewski was an assistant under Walton at Florida from 2013-15.

“I miss being around him a lot, to be very honest,” Gajewski said. “But it’s really cool to be able to showcase his team and our team on this stage, and to be able to do that is just an incredible thing.”

The Cowgirls are in the WCWS for the fifth consecutive season, the longest streak outside of Oklahoma (eight).

The Gators are led by SEC Player of the Year Jocelyn Erickson, an Oklahoma transfer.

“She’s been a phenomenal addition,” Walton said.
