Ames, IA (SportsNetwork.com) - Georges Niang poured in 23 points and grabbed eight rebounds, leading 15th-ranked Iowa State to an 83-66 victory over TCU on Saturday at Hilton Coliseum.

Monte Morris contributed 16 points and six assists for the Cyclones (16-4, 6-2 Big 12), who were coming off a three-point win on Monday against Texas and extended their home winning streak to 19 consecutive games.

Bryce Dejean-Jones also scored 16 points and Dustin Hogue added 12 in the victory. Each of the Cyclones' first seven conference games had been decided by single digits, but Iowa State used a couple of second-half runs to make it a laugher after leading by only two at halftime. Niang scored 17 points after the intermission.

Trey Zeigler scored 14 points for TCU (14-7, 1-7), which has lost four in a row. The Horned Frogs were 13-0 before conference play began in January.

Kyan Anderson, TCU's leading scorer at 13.9 points per game, made just 3-of-13 shots and finished with eight points.

"We had an opportunity there to start the second half," said TCU coach Trent Johnson. "I thought we did a good job of executing in the half-court, and we didn't finish. We didn't finish some plays around the rim. We didn't finish some open jump shots, and versus a team like this, that puts you in a bad spot, especially on the road."

Iowa State ran off nine straight points to turn a two-point deficit into a 16-9 lead seven minutes into the contest, but TCU answered with eight in a row to move back in front. It stayed close through the end of the half, as the Cyclones led by as many as five at 33-28 before a Zeigler layup and Brandon Parrish three pulled the Horned Frogs even in the final minute.

Morris, though, put Iowa State back on top with a layup just before the halftime buzzer and the Cyclones started the second half with a 10-2 run. Niang and Hogue each scored four during the early burst, giving Iowa State a 45-35 advantage.

Five quick points cut the TCU deficit in half and the Horned Frogs were still down five at 52-47 before Iowa State put it away with a 14-4 run. Niang, Morris and Dejean-Jones each scored four during the spurt, with two free throws by Dejean-Jones giving the Cyclones a 66-51 cushion with 6:41 remaining.

The Horned Frogs never threatened again and suffered their fifth straight loss to the Cyclones.

Iowa State shot a blistering 63 percent in the second half and finished at 56.4 percent for the contest, while also dominating the boards with a 44-30 advantage.

"I thought we played much smarter in the second half," said Iowa State coach Fred Hoiberg. "We were playing stupid in the first half, trying to squeeze passes into small spaces and our spacing on the break was brutal. The second half was much better all across the board."

The Cyclones will head to Kansas on Monday to battle the Jayhawks, who lead the Big 12 with a 7-1 mark. Kansas' lone conference loss came at Iowa State on Jan. 17.
