Kansas State was limited to 16 first-half points, which was the third-lowest halftime point total against the Jayhawks this season (TCU - 9; Texas - 15). It was also the fewest scored by K-State this season in the first 20 minutes.
KU scored 24 points in the first half, which was the second-fewest scored by the Jayhawks this season.

Senior Jeff Withey collected a team-high 17 points on the night for his 27th double-figure scoring effort of the season and the 45th of his career. He has scored double-digits in 16 of his last 18 games.
Withey was named a member of the All-Big 12 Tournament team and the Most Outstanding Player, becoming the first player at KU to receive the honor since Marcus Morris in 2011.
Freshman Perry Ellis also earned a spot on the all-league tournament team, giving KU two selections for the first time since the 2011 event. Ellis also became the first freshman on the team since Texas' Tristan Thompson in 2011. He is the first KU freshman since Mario Chalmers and Julian Wright in 2006.
Ellis finished the tournament with a team-best 43 points and also shot 18-for-23 (78.2%), which is a new KU tournament record, topping Wayne Simien's 65.6% effort in 2005.
Ellis' three-point field goal at the 6:14 mark of the second half marked the second made trey of his career. He is now 2-for-3 on the season.
For the second-straight game, Ellis has posted a double-digit scoring effort, the first back-to-back double-figure games of his career. Ellis scored a career-high 23 points against Iowa State in Friday's semifinal and followed up with 12 in the final against Kansas State.
Withey also added nine rebounds, giving the KU senior 31 games this season with five or more boards.
