AMES — Milan Momcilovic scored 18 points and No. 5 Iowa State shook off a slow start to defeat No. 9 Kansas 74-56 on Saturday, snapping the Jayhawks’ eight-game winning streak.

The Cyclones (22-3, 9-3 Big 12), coming off Tuesday’s 62-55 loss at TCU, began a five-game stretch in which they play four ranked teams by taking control of this game in the first half despite struggling to make shots in the opening minutes.

Iowa State led 37-27 at halftime, then went on a 20-7 run in the opening 5 1/2 minutes of the second half, a stretch in which the Cyclones made six consecutive 3-pointers.

Their defense held Kansas (19-6, 9-3) to 31.6% shooting from the field in the second half, including 1 of 8 in 3-pointers. The Jayhawks shot 37.3% for the game while committing 13 turnovers, 10 in the first half.

Tamin Lipsey, Joshua Jefferson, Blake Buchanan and Jamarion Bateman each had 11 points for Iowa State.

Melvin Council Jr. led the Jayhawks with 15 points, and Flory Bidunga had 11.

No. 6 Iowa St. 70, No. 2 Houston 67

AMES — Nate Heise hit a go-ahead 3-pointer and Tamin Lipsey came up with an offensive rebound in the final seconds to cap No. 6 Iowa State’s rally in a 70-67 victory over Big 12 leader and second-ranked Houston on Monday night.

Heise was 3 for 3 from 3-point range hours after sister Taylor Heise scored to help the U.S. Women’s Olympic hockey team beat Sweden 5-0 to reach the gold-medal game in Milan.

The Cyclones (23-3, 10-3) closed with a 17-4 run to take down a second top-10 team in three days. Iowa State topped No. 8 Kansas 74-56 on Saturday.

The Cougars (23-3, 11-2) had their six-game winning streak snapped and their conference lead was cut to a half-game over No. 4 Arizona heading into their matchup Saturday in Houston. Iowa State is third, a game behind Houston.

Heise hit the 3-pointer from the left corner with 1:17 to play to give the Cyclones a 69-67 lead. Houston had two chances to tie or take the lead, but was called for a shot-clock violation with 43 seconds to play, then Chris Cenac Jr., missed a shot with four seconds left.

Blake Buchanan was fouled after rebounding Cenac’s miss, but missed the front end of a one-and-one. Lipsey, though, got the offensive rebound, tapping the ball back to Joshua Jefferson, who was fouled with a second left. Jefferson made his first free throw for the final margin.

Jefferson led Iowa State with 12 points. Heise had 11 and Buchanan had 10.

Kingston Flemings led Houston with 22 points.

Emanuel Sharp had 16 points, all in the first half. Milos Uzan had 11 points.
