Gabe Kalscheur buried a step-back three with 3.5 seconds left to lift the No. 25 Iowa State men’s basketball team to a 69-67 victory over No. 17 TCU in Fort Worth on Saturday.

The Cyclones led nearly the entire game but let a 9-point lead slip away in the final three minutes to allow TCU to grab a 67-66 lead in the final minute before Kalcheur’s heroics.

Kalscheur led four Cyclones in double-figures with 15 points in the contest. The Cyclones improved to 3-0 in Big 12 play, something they haven’t done since the 1999-2000 season.

Iowa State is now 12-2 overall and will host Texas Tech next on Tuesday.
