It was just the third shot DeLozier has taken all season, and the junior from Houston has scored just twice in her career. Kristen Kelley headed in a goal in the 63rd minute and Megan Marchesano scored her seventh goal of the season with 16 1/2 minutes left to add insurance for the defending champion Cowgirls.
"I looked up, had some open space, so I decided to rip it," DeLozier said. "And there it went."
Oklahoma State (16-3-1, 8-2-0 and ranked 11th nationally) will play No. 3-seed Nebraska in a semifinal match Friday at 8 p.m. The Cornhuskers used three first-half goals to defeat sixth-seeded Missouri, 4-1.
Friday's other semifinal, which starts at 5:30 p.m., will match top-seeded Texas A&M against fourth-seed Oklahoma. The Aggies needed penalty kicks after a scoreless game to defeat eight-seeded Colorado, and Oklahoma won 1-0 over fifth-seed Texas.
Seventh-seeded Texas Tech (11-8-1, 4-5-1) lost its regular-season meeting with OSU, 2-0, on Sept. 26 in Stillwater. That was the second of seven-straight victories the Cowgirls compiled to open Big 12 play. But they came into the tournament losing two of their last three.
"I was happy today," OSU coach Colin Carmichael said. "I think Tech did everything they could to kind of disrupt the game and be aggressive and close us down. They created some scary moments for us."
Tech lost its last two games heading into the tournament, and the Raiders have not defeated a team that advanced to the conference tournament since Oct. 1 when they beat Colorado.
They got little going against OSU, and they had to count on Big 12 Rookie of the Year Jessica Fuston to generate much of it. After forcing OSU goalkeeper Adrianna Franch to get low to block a 10-yard shot five minutes into the second half, Fuston helped Tech avoid the shutout by heading one past Franch and into the corner of the goal with 4 ½ minutes left in the game. It was her 11th of the season.
"We played eons better than we did in Stillwater," Tech coach Tom Stone said. "We had players playing all over the place to get a team on the field tonight, and I thought the girls played their absolute hearts out. We have nothing to be ashamed about. That's a top-10 team in the country."
DeLozier, however, was an unlikely scorer, and she wound it up from just as an unlikely spot on the field. She was about 35 yards out, and her kick bounced before it found the left side of the goal.
"It was cool," DeLozier said. "I'm not really one to look to for scoring purposes. I think helping the morale got us playing and getting the ball down a little better."
Kelley's goal, her third this year, came when she circled around her defender to get eight yards in front of the goal and in position to head in a long, high pass from Catherine Parish. Marchesano scored from almost as close as Kelley when she received a centering pass from Krista Lopez.
