KANSAS CITY, Mo.-- Ben McLemore scored 24 points as No. 7 Kansas easily defeated Texas Tech, 91-63, in the quarterfinals of the Big 12 Tournament on Thursday at Sprint Center.
The top-seeded Jayhawks will face Iowa State in the semifinals Friday evening. Iowa State defeated Oklahoma, 73-66, in the first game of the day.
Kansas (27-5, 15-4) opened the second half on a 14-4 run to erase any thoughts of a comeback by Texas Tech (11-20, 4-16). That was added to a 7-0 run to close the half for the Jayhawks.
Once the Jayhawks opened a 20-point lead, coach Bill Self started resting his starters in preparation for three possible games in three days.
McLemore was joined in double figures by seldom-used Rio Adams with 11 points, but six other players scored at least six points. The Jayhawks had a 39-25 in bench points.
Tech was led by Dejan Kravic with 20 points. Dusty Hannahs added 15 points.
Kansas dominated inside throughout the game. The Jayhawks had a 34-22 edge in points in the paint. The Jayhawks' inside advantage was largely because of a difference in field goal percentage. The Jayhawks shot 66 percent, compared to just below 40 percent for the Red Raiders.
Kansas started quickly, outscoring the Red Raiders 8-0 and 15-2 before Tech got moving. McLemore had 12 of the Jayhawks' points at the start. But Kravic kept Texas Tech in the game with 11 points in the first half, including nine straight Red Raiders' points at one point.
The Red Raiders got as close as two points at 27-25 before Kansas scored the last seven points of the half.
