MANHATTAN, Kan. (AP) -- Michael Beasley had 33 points and 15 rebounds to lead Kansas State to an impressive 82-57 win over Iowa State and setting up a mammoth showdown with No. 2 Kansas on Wednesday.
Beasley, who ranks fourth nationally in scoring and first in rebounding, topped 30 points for the seventh time this season, tying him with Bob Boozer and Norris Coleman for the most 30-point games in a single season in school history.
Jacob Pullen added 13 points, Bill Walker had 10 points and nine rebounds and Darren Kent came off the bench to score 11 points for the Wildcats (14-4, 4-0 Big 12), who won their fifth straight and moved to 4-0 in conference play for the first time since 1988.
The Wildcats' victory sets the stage for the arrival of the Jayhawks, who beat Nebraska earlier in the day to move to 20-0 overall and 5-0 in the Big 12.
Kansas State hasn't beaten Kansas in Manhattan since 1983, and the Wildcats are 0-19 against the Jayhawks in Bramlage Coliseum.
And after Baylor's loss to Oklahoma on Saturday, Kansas State and Kansas are now the only two remaining unbeaten teams in Big 12 play.
After struggling through a sloppy first half against the Cyclones, Kansas State exploded in the second half as Beasley scored 16 points in the first nine minutes after the break.
Beasley's baseline jumper started a 23-11 run that was capped when Fred Brown stole the ball and raced down the court for a dunk, lifting the sellout crowd to its feet and giving the Wildcats 74-41 advantage.
At one point Beasley had seven straight points during that stretch, scoring on back-to-back putbacks and then converting another layup while being fouled by Jiri Hubalek.
Wesley Johnson had 20 points to lead the Cyclones (12-8, 2-3), who had their second straight lopsided defeat, after losing 83-59 at Kansas on Wednesday.
Craig Brackins added 10 points for Iowa State, which struggled throughout the game to handle Kansas State's pressure defense and find good shots.
The Cyclones finished just 33 percent from the field, and went scoreless for nearly four minutes while Kansas State put the game away in the second half.
Kansas State looked out of sync offensively for much of the first half, but then got it going just before halftime. The Wildcats started hitting shots from all over the court, and Clent Stewart even banked in a baseline 3-pointer with 1:40 left. Beasley, who had 17 points and six boards before intermission, sank another 3-pointer seconds before halftime to give the Wildcats a 46-30 lead.
