Va., on Wednesday.The Cougars (17-3, 9-0 Big 12) extended their winning streak to 13 games despite blowing most of their 20-point halftime cushion.

Sencire Harris added a steal and a layup at the 13:39 mark, and his free throw with 8:46 left narrowed the margin to 47-42, the smallest of the second half.The Mountaineers closed to within five points with less than eight minutes to play, but Cryer assisted on a Tugler dunk before completing a three-point play aided by a goaltending call to stunt momentum.

Houston turned 13 offensive rebounds into 16 second-chance points in the game.Joseph Yesufu paced West Virginia with nine points off the bench while Amani Hansberry, Javon Small and Okani scored eight points each.
