Kevin Young had 14 points and Ben McLemore and Travis Releford added 13 apiece as the Jayhawks (26-4, 14-3 Big 12), who took a half-game lead over No. 9 Kansas State in their quest for a ninth straight conference title.
Fueled by Young and Withey, Kansas unleashed a 19-2 run and seized a 45-20 halftime lead. Withey and McLemore combined to score the first 10 points in a 16-3 run to open the second half.
Jordan Tolbert had 16 points for Texas Tech (10-18, 3-14), which lost 60-46 at home to Kansas earlier this season.
NO. 8 LOUISVILLE 67, CINCINNATI 51
In Louisville, Ky., Russ Smith scored 18 points and No. 8 Louisville gave Rick Pitino his 300th victory.
Pitino, who earned his 650th career win earlier this season against South Florida, picked up this milestone against Cincinnati counterpart Mick Cronin, a former Cardinals assistant in 2002 and 2003.
The Cardinals (25-5, 13-4 Big East) picked up their sixth consecutive win and drew within one-half game of first-place Georgetown, which plays at Villanova on Wednesday.
Louisville’s trademark defense ignited this victory, as the Cardinals forced Cincinnati (20-10, 8-9) into a season-high 21 turnovers.
AP POLL: Gonzaga, the small Northwest school known for big NCAA tournament wins, is No. 1 in The Associated Press’ Top 25 for the first time.
Riding the best record in Division I at 29-2, the Bulldogs took advantage of Indiana’s loss to Minnesota last week. The Bulldogs switched places with the Hoosiers, advancing from No. 2 to move comfortably into the No. 1 spot Monday.
“It’s an honor that people would think this highly of all of us in the program,” coach Mark Few said in a prepared statement Monday afternoon. “It’s great for the program, great for the school, great for the city of Spokane and the region and the entire Northwest.
“We still have a lot more to accomplish starting this weekend in Las Vegas and moving forward to the NCAA tournament,” said Few. “We’re looking forward to the rest of the season and making it last as long as we can.”
Gonzaga is the fifth school to hold the top spot this season. Indiana was the preseason No. 1 and on top for nine other weeks. Duke, Louisville and Michigan were the other No. 1s.
Duke stayed at No. 3 with five first-place votes. Kansas and Georgetown both jumped two spots to fourth and fifth. The Hoyas received the other two first-place votes.
