Sliwinski scored the go-ahead goal off of a deflection in the box to put second-seeded Baylor (16-1-4) up 2-1 with a little more than 10 minutes to play. BU would hold off a final flurry from the third-seeded Red Raiders (15-5-1) to claim the victory.
"The fact that we are in the Big 12 Championship final has not totally hit me yet," Baylor head coach Marci Jobson said. "I am just really proud of our effort tonight. We weathered some big storms and held our ground."
Baylor midfielder Hanna Gilmore notched her fourth goal of the season to give BU a 1-0 lead in the fourth minute. That goal was the earliest score by BU all season and the earliest goal Texas Tech has given up all season.
Tiffini Smith tied it up for the Red Raiders with a long header from outside the penalty box fifteen minutes later. That goal was Smith's first on the year and sixth of her career. It also put a stop to the Bears' 311-minute streak without allowing a goal and was only the 10th goal given up by the BU defense all year.
Baylor advances to the championship match for the first time in Conference history this Sunday at 1:10 p.m. CT where it will face No. 8 TCU. That game will be broadcast live on FSN.
