Jeff Hornacek sank six free throws in the final minute to help Iowa State hold off Kansas (19-3 overall, 4-1 in the Big Eight) and upset the fourth-ranked Jayhawks, 77-74, last night.

With Iowa State missing eight straight free throws -- seven of them one-and-ones -- Kansas whittled a 10-point deficit to one before Hornacek hit his shots to give the Cyclones (13-6, 4-2) their 13th straight victory at home.

Hornacek sank two free throws with 59 seconds left and two more 32 seconds later to give Iowa State a 75-70 lead. A jumper by Kansas' Cedric Hunter cut the lead to 75-72 with 23 seconds to go, but Hornacek made two more free throws two seconds later.

Ron Kellogg scored Kansas' final basket with 13 second remaining and Iowa State ran out the clock.

Kansas had kept it close behind Danny Manning's 26 points and Iowa State's poor free throw shooting.
