The Pac-12 Conference will remain at a dozen teams as the league's presidents and chancellors voted to reaffirm their decision to stand pat.
"After careful review we have determined that it is in the best interests of our member institutions, student-athletes and fans to remain a 12-team conference," Pac-12 Conference commissioner Larry Scott said.
Texas, Oklahoma, Oklahoma State and Texas Tech were among those considering a potential move from the Big 12.
After expanding from the Pac-10 with new members Utah and Colorado last year, members of the new Pac-12 won't give them the chance.
The league already negotiated a landmark 12-year television contract with Fox and ESPN worth about $3 billion. And it appears plenty happy at a dozen.
"While we have great respect for all of the institutions that have contacted us, and certain expansion proposals were financially attractive, we have a strong conference structure and culture of equality that we are committed to preserve," Scott said. "With new landmark TV agreements and plans to launch our innovative television networks, we are going to focus solely on these great assets, our strong heritage and the bright future in front of us."
Sally Watson captured the individual title and Stanford shot a final round 292 on Tuesday to finish second at the Cougar Cup hosted by Washington State.
Watson rebounded from an opening round 79 with rounds of 71 and 70 to win the tournament. She birdied four of the last 12 holes, sinking a 40-foot putt on her final hole to clinch the victory. Her 220 tied the second-lowest total in tournament history.
The Cardinal's 54-hole hole total of 902 trailed first place Washington by 12 strokes. The Huskies set a Cougar Cup record with an 890.
Marissa Mar and freshman Mariko Tumangan, playing her first tournament, tied for eighth individually, each with a 226.
Sydney Burlison, Kristina Wong, and Danielle Frasier finished tied for 14th at 228.
