LAWRENCE, Kan. — Curtis Stinson scored all seven of Iowa State’s points in overtime, including the game-winner in the lane with 5.1 seconds left, to lead the Cyclones to a 63-61 upset of No. 2 Kansas on Saturday, their seventh straight Big 12 victory after opening the conference season 0-5.

The winning streak has completely turned around the season for the Cyclones, not only salvaging what appeared to be a lost year but moving them into contention for an NCAA bid.

Kansas’ Keith Langford tied it 56-all with a 4-footer over Jared Homan with 6 seconds left in regulation as the Jayhawks erased a nine-point deficit over the final 2 minutes.

Stinson, who had 29 points, hit the short jumper for the winning basket over Langford right after he had missed two free throws at the other end. Langford missed a desperation 3-point attempt at the buzzer.

The Cyclones (15-8, 7-5) have beaten four ranked teams in the streak and have won three road games. Before the streak, the Cyclones had not won a conference road game in almost 4 years.

Iowa State used its aggressive zone defense to hold Kansas (20-3, 10-2) to its lowest point total of the year and hand the Jayhawks their first conference loss at home in 32 games.

The Jayhawks, who lost by one point in double overtime on Monday night at Texas Tech, shot only 35 percent against Iowa State. J. R. Giddens was 3-for-16 from the field, including 1-for-11 beyond the 3-point arc.

Kansas, which had won 20 straight overall on its home court, took a 59-56 lead in overtime before Stinson, with two free throws and a short jumper, made it 60-59.

Then Wayne Simien’s two free throws made it 61-60 before Stinson made one of two from the line and tied it 61-all.

Stinson, the sophomore guard who leads the Cyclones in scoring, did not enter the game until 15:35 remained in the first half.

Simien led the Jayhawks with 17 points and 11 rebounds.

Homan, who fouled out in overtime, had 14 points for Iowa State.

Rahshon Clark’s basket with 3:27 left in regulation gave the Cyclones their biggest lead, 53-44. Then at the 1:37 mark, Michael Lee hit a 12-footer and ignited an 8-1 run.

Iowa State was the last Big 12 team to win in Allen Fieldhouse, a 79-77 victory on Feb. 5, 2001.
