FORT WORTH, Texas (AP) — Jayden Pierre’s 3-pointer put TCU ahead with 48 seconds left and the Horned Frogs scored the final 12 points to upset No. 5 Iowa State 62-55 on Tuesday night.

Tanner Toolson had 17 points and nine rebounds off the bench for TCU (15-9, 5-6 Big 12), which earned its first victory over a top-five team since beating No. 3 Houston in January 2024. Micah Robinson also scored 17.

Pierre’s pull-up 3 gave the Horned Frogs a 57-55 lead, and Xavier Edmonds stole the ball from Iowa State point guard Tamin Lipsey near midcourt on the ensuing possession. That started a fast break, which Robinson finished with a dunk to make it 59-55 with 28 seconds remaining.

Lipsey then missed the front end of a 1-and-1 before Toolson sank three free throws to seal it.

Joshua Jefferson had 12 points, nine assists and eight rebounds for the Cyclones (21-3, 8-3), who had won five straight. Lipsey also finished with 12 points, but Iowa State went scoreless over the final 2 1/2 minutes.

TCU scored 19 points off 17 Iowa State turnovers.

The Cyclones appeared in control after their 10-0 run erased an eight-point TCU advantage with just under five minutes remaining. But after taking a 55-50 lead on Nate Heise’s layup with 2:38 to play, Iowa State didn’t score again.

Iowa State forced 15 turnovers, including five during a six-minute stretch when the Horned Frogs were held without a field goal. Robinson’s dunk with 2:14 remaining snapped the 7:15 dry spell and cut the Cyclones' lead to 55-52. Pierre’s hook shot pulled TCU within one with 1:35 left.

Iowa State led by nine in the first half, but TCU went on a 10-0 run to grab a brief lead behind five points each from Robinson and Toolson. Jefferson’s layup as time expired stopped the spurt and gave the Cyclones a 30-29 lead at halftime.
