DALLAS -- The celebrations are always fun for top-ranked Baylor. Brittney Griner and the Lady Bears have had plenty of practice.

Now the defending national champions can turn their focus toward trying to win the biggest prize one more time with their 6-foot-8 senior star.

The Lady Bears have another trophy to show for their dominating run through the Big 12, clinching their third straight conference tournament championship with a 75-47 victory over No. 23 Iowa State on Monday night.

"Winning never gets old, especially this one," said Griner, one of five Baylor seniors. "We wanted to celebrate this, everybody did. This is our last go-around with the Big 12. Meant everything to us."

Along with their three tournament titles in row, the Lady Bears (32-1) have won the last three Big 12 regular-season championships as well - going undefeated through the league for the last two.

They have won 49 consecutive regular-season and tournament games in the Big 12, though that streak doesn't include the NCAA regional final loss to then-conference foe Texas A&M two years ago in the American Airlines Center, where they won their latest tournament title.

"We had that epic disappointment along the way. I'm never going to forget that," coach Kim Mulkey said. "Those kinds of things motivate us."

Griner, already a two-time All-American, had 23 of her 31 points by halftime - outscoring Iowa State by 10 points on her own by then in a title game matchup of the Big 12's top two seeds.

It was Iowa State coach Bill Fennelly who said after a 28-point loss at Baylor early in conference play that the Big 12 race was basically to determine who finished second behind Baylor.

The Cyclones wound up the runner-up both in the regular season and the tournament.

"They are different than anyone in the country," Fennelly said. "They've proven that over the last two years."

Odyssey Sims added 20 points for Baylor, including three 3-pointers in the first 4 minutes after halftime.

Anna Prins had 20 points and Nikki Moody 12 for the Cyclones (23-8) in their first Big 12 title game since 2007.

Iowa State got off to a good start with Prins making a 3-pointer on its opening attempt before another long-range shot by Hallie Christofferson for a 6-5 lead. But the Cyclones then went more than 8 minutes without scoring, a span in which they missed six shots and had eight turnovers while Baylor scored 19 points in a row for a double-digit lead that only got bigger.

Baylor had the lead for good at 7-6 on Griner's putback after she grabbed the rebound of her only missed shot out of 12 attempts in the first half.

The Lady Bears were up 41-13 at the break, holding Iowa State to the fewest points ever in a single half of a Big 12 tournament championship game.

Baylor's fifth Big 12 tournament title - all coming in a stretch that began in 2005, the year of its first national title - broke a tie with Oklahoma for the most in the league.

The Lady Bears will surely be the No. 1 overall seed in the NCAA tournament and will play their first games in two weeks on the Waco campus, where they have won a nation-best 55 games in a row. They have won 30 straight overall since losing against Stanford at a tournament in Hawaii a week into the season.

"It's always good to send a statement going into the NCAA tournament," Sims said. "We're just going out there having fun, one game at a time."

Griner finished 14 of 17 shooting and had as many field goals as Iowa State's entire team when she came out of the game for good with 4:12 left.
