With the win, the No. 2 Cowgirls finish 6-0-2 in conference play and head to the postseason with a 17-0-2 overall record. OSU becomes only the second Big 12 team, along with the 1996 Nebraska squad, to complete the regular season undefeated, and the Cowgirls are the first team since Texas A&M in 2002 to finish Big 12 play without a loss.

"It was tough," said OSU coach Colin Carmichael. "To go through the season undefeated you have to show a certain level of consistency, and I think that's been the biggest factor for our team. We play better some nights, but our level of play hasn't dropped significantly — we've always put on a pretty good show....

"It feels amazing. Fifteen years ago, when Karen (Hancock) and I were doing this, you couldn't have imagined this. A lot of hard work from our staff and our former players, it's been building up to this. And to win four championships is just an amazing accomplishment for our kids."

The conference championship marks the fifth in program history for OSU. The Cowgirls also won the Big 12 regular season title in 2008 and have claimed the league's postseason tournament title three times (2003, '09, '10).

Thursday's record-setting win didn't come easy. Texas Tech (10-7-2, 3-4-1) outshot the Cowgirls by a 17-15 margin, but OSU got a pair of timely goals and recorded yet another shutout. That shutout also tied a record as it marked OSU's 14th of the season, a total the Cowgirls also reached in 2009.

OSU nearly gave up a goal early on as just 1:29 into the match Taylor Lytle blasted a shot that bounced off the far post.

The game remained scoreless until the 40th minute. OSU won a corner kick, and Taylor Mathews sent the ball towards the box. The ball deflected off the foot of a Red Raider defender and into the net to give the Cowgirls a 1-0 lead and Mathews her sixth goal of the season.

The Cowgirls nearly added another goal just before intermission, but a shot by Kristen Kelley was saved off the line by a Tech defender to keep the score at 1-0.

OSU added its second goal in the 64th minute on a highlight-reel score by Kyndall Treadwell, who collected a loose ball and ripped a 20-yard shot to the top shelf to put the Cowgirls up by two.

That was more than enough for the Cowgirls as goalie AD Franch and company kept the Red Raiders off the scoreboard. Franch finished with a season-high seven saves to notch her eighth shutout of the season.

The win sent eight Cowgirl seniors out in style in their final regular season home game as that group won its 70th career game.

Said Treadwell of the undefeated season and another Big 12 championship, "It's awesome. "It's a goal we set, and it's a big accomplishment for us."

Carmichael added that this record-setting senior class will leave an indelible mark on the OSU program.

"You can't really describe what they've done for this program," Carmichael said. "They're the fourth-winningest class in the NCAA out of 330-something teams. That gives you an idea of the level that they're playing at. I can't speak highly enough of them as players and people. They're great ambassadors for our program and the university."
 

OSU's best opportunity for the equalizer came on a pair of shots off a corner kick in the 29th minute. After Mercado's header was saved, Katie Richardson had a chance for a putback but was also denied as an OU defender saved the ball off the line.

The Cowgirls also missed out on scores late in the half when shots by Taylor Mathews and Elizabeth DeLozier sailed over the crossbar.

OSU converted what appeared to be its first goal with 4:32 remaining until intermission, but the Cowgirls were whistled for offside to erase DeLozier's score off a corner kick.

The Sooners would take the 1-0 lead into halftime, despite OSU outshooting its rival by a 10-4 margin and owning a 6-1 advantage in corner kicks.

OSU's opportunities finally resulted in the equalizer with just over 20 minutes remaining in the match.

After OU defender Kathryn Watson failed to clear the ball, goalie Kelsey Devonshire was left out of position. Kyndall Treadwell was there for the Cowgirls and converted the open net opportunity from 15-yards out for her fourth goal of the season and second of the tourney.

Franch would come up big once again for the Cowgirls in the 79th minute to keep OU from regaining the lead as she made a diving save on a shot by Dria Hampton.

A shot from six-yards out by Treadwell that sailed wide in the 87th minute provided OSU's final best chance at a second goal in regulation.

With five minutes remaining in the first overtime, it looked as if OSU would notch the game winner. Lopez sent a cross on the ground just in front of the goal line with a pair of Cowgirls in the area, but neither Mathews nor Katie Richardson was able to get a foot on the ball.

OU had the best scoring chance in the second overtime, with Franch making yet another diving save on a shot by Mooney to keep the Sooners off the board.

"AD is basically our savior," Lopez said. "Everybody doesn't realize how big of a role goalkeepers play in winning games. She really made some great saves, and those pump us up and give us confidence. She was really big in helping us get this win."
 

The win was the eighth in a row for the Cowgirls, the tourney's No. 5-seed, as coach Colin Carmichael's squad improved to 15-7 on the season and clinched a berth in the NCAA Women's Soccer Championship. OSU will be making its fourth-straight NCAA appearance.

OSU's victory also marked its first ever against Texas A&M (14-6-2). The Cowgirls entered the contest 0-14-2 all time against the Aggies.

"It's so exciting to win and beat A&M because I've obviously never beaten them," said OSU senior captain Bridget Miller. "It's just an awesome feeling. We were motivated even more because we knew the only chance we had to get into the NCAA Tournament was to win (the Big 12 tournament). We all had that on our minds all week, and I think that helped us."

Freshman Carson Michalowski scored the game's lone goal in the 53rd minute to lift the Cowgirls to the win. Off a corner kick from Colleen Dougherty, Michalowski raced in and delivered a header into the back of the net to put OSU up 1-0. The goal was the third of the season for Michalowski, while Dougherty notched her fifth assist.

"It's always going to be a great game with Texas A&M; they're a great program and a great team," Carmichael said. "We knew it was going to be very difficult, and I thought over 90 minutes we just edged it. (TAMU) certainly had their chances late.

"It was a great game that could have gone either way, and I'm just really proud of our kids for battling and pulling out the win."

OSU was the aggressive, attacking team in the opening half, but the first half ended scoreless, with the Cowgirls outshooting TAMU by a 6-3 margin.

Kyndall Treadwell had a pair of strong shots early for the Cowgirls, but her first was saved by TAMU goalie Kristin Arnold and her second carried just wide of the near post.

OSU continued its scoring chances 12 minutes into the match, but a shot from just outside the box by Annika Niemeier sailed over the crossbar.

Minutes later, it was TAMU looking at a prime scoring opportunity. But Michalowski came up big as she was able to knock the ball away from Whitney Hooper as Hooper tried to make a move from just outside the 18-yard box.

OSU continued its attacking ways, and again created another chance for Treadwell, this on off a cross by Niemeier with just over 21 minutes remaining in the half. But Treadwell's header was wide, and the Cowgirls remained scoreless.

The Aggies came out the aggressor early in the second half and created their best scoring opportunity just over six minutes in as Nora Skelton broke free and blasted a shot from just outside the six-yard box. But AD Franch made a diving save to keep the shutout intact.

But the shutout did not last long, with Dougherty and Michalowski connecting for the game-winning goal.

In the 68th minute, TAMU had several furious rallies in front of the goal, but the Cowgirl defense was able to keep the Aggies off the scoreboard to preserve their lead.

That stellar defensive play continued with TAMU pressing to score late. The Aggies had nine shots in the second half, with Franch recording six saves after intermission. Franch finished with seven saves, one shy of her career high.

"It starts with AD (Franch), and you have (Melinda) Mercado and Michalowski right in front of her. Those girls have been phenomenal," Carmichael said. "And the wide backs with Whitney (Wernimont), Allyson (Leggett) and Colleen (Dougherty) did a great job. It's a team effort when you defend against a good team, and we're thrilled that AD, Mercado and Michalowski are in the heart of that defense because they're really tough to beat."

OSU had six players named to the Big 12 Championship All-Tournament team: Franch, Niemeier, Mercado, Kasey Langdon and Siera Strawser. Mercado was named the tourney's defensive MVP.
 

With the win, the eighth-ranked Cowgirls finish Big 12 play with a 7-1-2 mark and complete the regular season 16-1-2 overall.

"It feels great for everybody associated with the program," said OSU head coach Colin Carmichael. "It's a testament to the kids who have been here in the past and helped us build the program and the ability and the hard work of the current bunch of players.

"To win the Big 12 regular season shows consistency, and that we really got to a level where we can compete with anybody."

OSU will be the No. 1 seed at next week's Big 12 Soccer Championship in San Antonio and will open play Wednesday against Texas Tech. Friday's win against OU also marked the Cowgirls' fourth straight against the Sooners, and their 16 wins are the second most in school history.

"I can't put it into words," OSU senior defender Jessica Jarrell said of winning the league title. "It's beyond exciting. We've worked so hard for four years to get to this point. To be a senior leader on the first OSU team to ever win a championship is amazing.

"My first year, I watched teams like Texas and Texas A&M and Colorado play beautiful soccer, and we weren't to that level yet. I didn't know if we'd ever get to that level, but we really made it. We're here!"

It wasn't easy for the Cowgirls on Friday as OU (3-15-1, 2-7-1) played Carmichael's squad even through the first 45 minutes of the match.

OU was the first to get on the scoreboard. In the ninth minute, Jordan White took a pass from Ashley Farrand and found the back of the net from 15 yards out to put the Sooners up 1-0.

The Cowgirls collected the equalizer in the 25^th minute as Kyndall Treadwell blasted a shot from 25 yards out to the far upper post to knot the score. The unassisted goal was Treadwell's eighth of the season and first since Sept. 26 against Texas Tech.

OSU took the lead with just 7:39 remaining before intermission. After OU's Claire West took OSU's Siera Strawser down in the box, the Cowgirls were awarded a penalty kick. And for the third time this season, Annika Niemeier stepped up and blasted the shot into the back of the net to put the Cowgirls on top.

But this time, OU would answer following a penalty. Off a free kick by Sage Coralli in the 42^nd minute, Kelsey Kraft sent a shot past Cowgirl goalie Erin Stigler to make the score 2-2.

OSU needed just over five minutes into the second half to regain the lead. Big 12 assist leader Kasey Langdon recorded her 13^th assist of the season as she sent a pass to Siera Strawser, who made a move around a defender and delivered her 10^th goal of the season.

The Cowgirls doubled up their lead in the 59^th minute when, after a mad scramble for the loose ball in the box, Melinda Mercado gained possession and recorded a goal from point-blank range to put OSU up, 4-2. The goal was Mercado's second of the season.

"OU did a great job in the first half of taking us out of our rhythm and fighting hard and making it tough for us," Carmichael said. "The second half, we did a much better job of getting the ball on the ground and moving them around. We were able to get a few more openings in the second half and took advantage of it."
 

Missouri jumped on top first, scoring just nine minutes into the contest. Elyse Nikonchuck took a shot from 20 yards out that rolled into the right corner of the net. Amber Swinehart assisted on the goal.

OSU had a great opportunity of its own with 12 minutes remaining in the period. Lisa Fulton started the play with a free kick, followed by a shot from Adriane Radtke that was blocked just in front of the keeper and a putback by Jolene Schweitzer that sailed over the crossbar.

Oklahoma State came out on a mission in the second half and scored nine minutes later. Katie Lacey took a shot that was blocked, and it became a free for all in front of the net. Marcela Nova followed with a second shot that was blocked, and Jere Boykin finished off the set with a shot that snuck in the right corner of the goal.

The Cowgirls took five shots on goal in the first 20 minutes of the second half, including a bullet by Carla Dolomont from 25 yards out resulting in a leaping save by Missouri's Megan Duncan.

Missouri then regained the lead at the 69:33 mark when Karen Bauer made a penalty kick after being taken down in the box, but it would not be enough for the Tigers.

The Cowgirls tied the game in the 80th minute when Boykin and Jolene Schweitzer teamed up for an exciting play. Boykin dribbled down the center of the field, passing to Schweitzer from about 30 yards out. Schweitzer then drew Missouri's goalkeeper out of the net and passed back to Boykin, who buried the shot from eight yards.

Neither team was able to break the standstill through the first overtime and much of the second. With just over one minute remaining, Boykin was taken down outside the penalty box and the Cowgirls were awarded a free kick from 20 yards out. Nikki Wojtowicz made good on the opportunity with a beautiful shot that found the back of the net and gave the Cowgirls the 3-2 win.

Three Cowgirls were named to the all-tournament team: forward Jere Boykin, midfielder Cassie Lewis and goalkeeper Kathrin Lehmann. Additionally, Lewis was named the offensive MVP and Lehmann the defensive MVP.

"I couldn't be prouder this group of kids," stated head coach Karen Hancock. "They showed a great deal of heart, character and determination in wining this championship. I love this group. They are awesome."
