KANSAS CITY, Mo. (AP) - Kansas wasn't about to share this title with Kansas State.

Jeff Withey had 17 points and nine rebounds, Perry Ellis and Naadir Tharpe added 12 points each, and the seventh-ranked Jayhawks pounded the No. 11 Wildcats 70-54 on Saturday night to win their ninth Big 12 tournament championship.

The top-seeded Jayhawks (29-5), who shared the regular-season title with their in-state rival, took a 24-16 lead at halftime and then slowly stretched it in the second half.

The Wildcats (27-7) struggled to match Withey and Ellis in the paint, losing for the third time this season to the Jayhawks and for the 47th time in their last 50 meetings.

Rodney McGruder scored 18 points despite a poor first half, and Angel Rodriguez had 10 for Kansas State, which still has not won a conference tournament in more than 30 years.
