The Red Raiders (20-4, 8-3 Big 12) extended their winning streak to five consecutive games and are the first Big 12 standings team.

The Red Raiders also kept pace with 13-time defending champion Kansas in the Big 12 standings.
Texas Tech has secured victories in 20 of its first 24 games for the third time in program history.
Texas Tech begins a stretch of three of its next four on the road and takes on Kansas State on Saturday. Tipoff is slated for 7 p.m. CT from Bramledge Coliseum.
