The Red Raiders (16-10, 6-9 Big 12) needed victories in its final two games to finish the season with a .500 conference record and enhance its NCAA Tournament chances. They fell to 0-4 at home against ranked opponents, and remained seventh in the Big 12.
Langford scored six points in a 10-2 spurt as Kansas (23-6, 13-2) took the lead for good with 11 minutes left in the first half, 16-8. The Jayhawks took a 39-28 advantage at the break.
Langford, a Texas native, scored six points in a 10-2 spurt as Kansas (23-6, 13-2) took the lead for good at 16-8 with 11 minutes left in the first half. The Jayhawks took a 39-28 advantage into halftime after shooting 61 percent (17-of-28) in the first 20 minutes.
"Our offensive execution was really the key to the game," said Kansas Coach Roy Williams. "We were unselfish, we moved the ball. In the first half, that was really important that we moved the ball well."
"In the second half, we were kind of in there and (Kirk) Hinrich made a big basket, a three-pointer from deep in the corner," said Texas Tech Coach Bob Knight. "The kind of shot that kind of sticks a pin in your balloon."
A jumper by Andre Emmett with five minutes remaining pulled Texas Tech to within 59-53, but Aaron Miles sank a short jumper and added a steal and a layup for a 10-point advantage with 4:24 to go.
Meanwhile, Texas Tech, which looked like a strong candidate for a second straight NCAA Tournament berth after completing its non-conference schedule with a 10-1 mark and wins at Minnesota and San Diego State, has struggled throughout its Big 12 schedule. Seven of its nine conference losses have been by nine points or fewer, including Saturday's 76-71 home loss to Texas.
