AMES — It's been quite a while since Iowa State basketball experienced the bitter taste of defeat at home.

Kansas State (10-11, 4-6 Big 12), which entered Saturday's matchup in Ames winless in true road games this season, stunned the third-ranked Cyclones, 80-61.

The loss ends Iowa State's 29-game winning streak at Hilton Coliseum.

Kansas State is the first under-.500 team to beat a team ranked in the top-5 of the AP poll by 15 or more points in the poll's history, according to ESPN's Jeff Borzello.

Tamin Lipsey paced the Cyclones (17-4, 7-3 Big 12) with 20 points. Curtis Jones had 14 points but shot just 1-of-10 in the second half. Joshua Jefferson had 13 points.

"It wasn't an effort that we're proud of at all," Iowa State coach T.J. Otzelberger said. "Definitely different than our standard, what we expect and what we've demonstrated through the first 20 games so that one was different. Extremely disappointing because the areas that we really focus to demand on, especially rebounding, the rebounding thing was the difference in the game. There was a point in the game where it was 15-0 in second-chance points."

Kansas State dominated on the glass, outrebounding the Cyclones 39-29. The Wildcats had 21 second-chance points, while Iowa State only had six.

The Cyclones shot 19-of-52 overall (36.5%) and 8-of-18 (44.4%) from deep. They shot 27.3% in the second half, including a 22.2% mark from long range. They also committed 18 turnovers in the loss.

Frustration was mounting, momentum was going Kansas State's way and Iowa State coach T.J. Otzelberger was tagged with his first technical foul of the season. A few moments later, Kansas State's Brendan Hausen drilled a deep 3-pointer to cap off a 20-4 second-half run to give the Wildcats a 58-39 lead with 13:45 remaining.

Hausen raised both of his arms in celebration and Hilton Coliseum was no louder than a library.

Iowa State managed to regroup and string together a 13-0 run and cut the deficit down to six after an and-1 by Gilbert made it 58-52 with 10:06 left in the game.

"There's a point in the game where you're definitely trying to get your team's attention to play better, which we were certainly trying to do with halftime, dead balls, time outs, you name it," Otzelberger said of his technical foul. "We put ourselves in position when it was 58-52 to give ourself a chance and then we let them score two baskets right away and separate again and so I was frustrated with a lot of things in that moment, mostly the fact that we weren't as good as we needed to be defensively, but I was frustrated with some other things as well."

The Cyclones and the Hilton Coliseum crowd appeared to have a second wind, but that would be the closest Iowa State would get to catching Kansas State.

Hausen knocked down another 3-pointer to spark an 8-0 run for the Wildcats. Once Kansas State extended its lead back to double figures, it never dipped below that.

Every Kansas State starter scored in double figures. Dug McDaniel led the way with 20 points and five assists. Coleman Hawkins added 17 points, seven boards and four steals. Hausen finished with 15 points and three steals. Max Jones had 12 points, while David N'Guessan chipped in 10 points.

"I fully believe in this team and some people doubt us, and now, we're starting to win," Hawkins said. "I don't know if it's validation, you know what I'm saying? It's just, now we're winning."

Kansas State held a narrow 37-35 halftime lead. The Cyclones opened the game on a 13-4 run, but then started to have turnover issues.

At one point, Iowa State coughed up the ball seven times in a 5:32-long stretch, as Kansas State started to dig its heels and come back from a tough start. The Wildcats were also strong on the offensive glass and had numerous second-chance opportunities.

Iowa State started to tighten up its possessions towards the end of the first half, but it did most of its damage by drawing fouls and getting to the free-throw line to stay within reach of Kansas State before getting outscored 43-26 in the final 20 minutes of action.

The Cyclones are back on the road Monday night for a rematch with Kansas. Iowa State defeated Kansas in their earlier meeting on Jan. 15, 74-57 , at Hilton Coliseum. Tip-off is scheduled for 8 p.m. CT.

"I think every loss has a significant impact," Jones said. "Obviously, it hurts, especially at home, that stings for sure. We don't want to feel like this again, so we just use it as hunger and motivation to continue to keep getting better and win games."
