The Red Raiders (25-7) missed their final 10 shots from the floor and 13 of their last 14, going the final 7:26 without a field goal. Texas Tech shot just 19.4 percent from the floor after halftime, leaving the door open for seventh-seeded Baylor (19-14).

The Red Raiders led by 13 points at halftime and by 15 just over two minutes into the second half. Baylor rallied and made it a three-point game on Robert Wright’s driving layup with 26.5 seconds left.

A pair of free throws by Texas Tech’s Kevin Overton with 21 seconds remaining pushed the margin back to five. But the Bears answered with a 3-pointer from Nunn to make it 74-72.

Elijah Hawkins hit a pair of free throws to push it back to a four-point game before Wright’s lay-up again trimmed the lead to two. Christian Anderson then left the door open for Baylor when he missed two free throws with 5.8 seconds, but VJ Edgecombe’s running 3-pointer at the buzzer clanged off the rim and away.

Darrion Williams added 14 points, all in the first half, and Hawkins and Kerwin Walton had 12 points apiece for the Red Raiders.
