Boise, Idaho ? Five years ago, Oklahoma coach Sherri Coale could offer recruits little beyond a down-and-out program and a sparkling vision that was more sunshine than substance.

Stacey Dales and LaNeishea Caufield bought into it, and now they’re all going together to the Final Four.

Caufield scored 25 points and Dales had 20 points and nine assists as top-seeded Oklahoma rolled past No. 3 Colorado 94-60 Monday night in the West Regional final, sending the Sooners to San Antonio.

“These guys bought into a vision. They bought what I was selling,” said Coale, who went 5-22 in her first season as coach in 1996-97. “And we’re not finished. We’ve got a lot more work to do.”

Caufield shot 5-for-5 from three-point range in the second half and scored 14 points during a 32-6 burst that guaranteed Oklahoma (31-3) of becoming the first Big 12 team ever to reach the Final Four.

Jamie Talbert and Rosalind Ross each scored 12 for Oklahoma, which lost in the NCAA tournament’s third round the past two years. Coale has won three straight Big 12 titles but now has the Final Four she always believed she’d get.

“I’m speechless,” said Coale, in her sixth season. “I have thought about this for six years, and I know what I was going to say. Now, I have no idea.”

As the clock went under 1 minute, Oklahoma fans chanted, “Final Four, Final Four.” Players put on their championship T-shirts and hats as Colorado’s Virginie Delepine shot free throws at the other end of the floor.

“I’m thrilled to be going to the Final Four,” Dales said. “I’m savoring tonight.”

Oklahoma will play Duke in Friday’s national semifinals. The Blue Devils advanced by winning the East Regional, 77-68 over South Carolina.

Eisha Bohman led Colorado (24-10) with 18 points, but the Buffaloes committed 29 turnovers, 15 above their season average.

“The defensive pressure and their physical strength really affected us,” Colorado coach Ceal Barry said. “It’s been a long time since we’ve had 29 turnovers, and that was the difference.”

Dales was named regional most valuable player and was joined on the all-tournament team by Caufield and teammate Caton Hill.

The Buffaloes trailed 37-33 at halftime and used their superior size to hang with Oklahoma early in the second half. Colorado was within 46-42 on Tera Bjorkland’s three-point play with 15:35 to go.

But that’s when Caufield took aim from the right side and the Sooners simply flattened the Buffaloes, who couldn’t hold back the flood gates despite a series of timeouts by Barry.

“We just started to get lost in the game,” Caufield said.

The Sooners will join the Oklahoma men’s team in the Final Four.

It was another huge night for Oklahoma’s small and spunky coach. Coale, who stands 5-foot-5, won two state titles in seven years at Norman High School before taking over the Sooners.

After her early struggles, Coale built Oklahoma into a national contender.

“It’s a sign of a lot of hard work and a lot of hours in the gym,” Dales said. “Just to be associated with this program and these people is better than winning this game.”
