(BCSNN) - Top‑ranked Arizona just keeps rolling.

Freshman Koa Peat delivered 20 points and seven rebounds, while Anthony Dell’Orso and Jaden Bradley added 17 each as the Wildcats defeated TCU 86-73 on Saturday, extending their undefeated start to 16-0 and improving to 3-0 in Big 12 play.

Arizona never trailed, continuing the program’s best opening stretch since beginning the 2013-14 season 21-0. The win came only hours after No. 2 Michigan’s loss to Wisconsin trimmed the nation’s list of unbeaten teams to five.

TCU’s Tanner Toolson matched Peat with 20 points, but the Horned Frogs (11-5, 1-2) fell to 1-11 all‑time against No. 1 teams and suffered their second loss of the week to a ranked opponent after Tuesday’s overtime defeat at Kansas.

Arizona’s Motiejus Kirvas grabbed 10 rebounds and scored eight points as the Wildcats’ streak of 10 straight wins by at least 19 points came to an end — the longest such run since Duke’s 2003-04 team.

The Wildcats led by as many as 21 in the first half, but TCU trimmed the margin to seven with 6:56 remaining. Dell’Orso responded with a clutch three late in the shot clock, Peat scored inside, and Dell’Orso buried a baseline jumper to push the lead back to 14.

Earlier, with TCU threatening early in the second half, Arizona answered with an 11-2 burst fueled by five straight made shots, including consecutive threes from Ivan Kharchenkov, Bradley, and Brayden Burries. Burries’ triple capped the run and restored a 20‑point cushion.

Arizona now turns its attention to a rivalry matchup, hosting Arizona State on Wednesday.
