SAN JOSE, Calif. -- Koa Peat scored 20 points and fellow freshman Ivan Kharchenkov added 18 as top-seeded Arizona beat No. 2 Purdue 79-64 in the West Region finals on Saturday night, earning their first trip to the Final Four since 2001.

The Wildcats (36-2) won their 13th straight game by erasing a seven-point halftime deficit and ending a five-game skid in Elite Eight games. They had lost in the regional finals in 2003, 2005, 2011, 2014 and 2015.

Peat was 9 of 18 from the field, breaking Mike Bibby's school record for most points in the Elite Eight by an Arizona freshman. Kharchenkov was 7 of 11 from the field and added eight rebounds, while Jaden Bradley and Brayden Burries each scored 14.

Purdue (30-9) got 14 points and 10 rebounds from Oscar Cluff and 13 points and seven assists from Braden Smith, who scored 11 in the first half but was just 4 of 15 from the field for the game. The Boilermakers made 7 of 14 3-pointers in the first half but were just 1 of 8 after halftime.

The Boilermakers led 38-31 at halftime, outscoring Arizona 26-12 after being down seven early. The Wildcats scored seven straight to tie at 42, then took a 44-43 lead on two Jaden Bradley free throws with 14:34 remaining.

The Boilermakers went more than four and a half minutes without a field goal and Arizona extended to a 51-45 edge on an Anthony Dell'Orso 3-pointer with 12:09 to go. The Wildcats got the margin to 10 with 8:46 remaining, and Peat's dunk made it 68-55 with 5:35 to go.

Purdue took a 10-9 lead with 15:44 left in the first half on a Smith 3, significant because it was the first time in the tournament that Arizona trailed. The Wildcats responded with a 10-2 run to build a 19-12 lead, and during that run, Trey Kaufman-Renn picked up his second foul.

A 3 by Gicarri Harris gave the Boilermakers back the lead, and later back-to-back 3s by Smith and CJ Cox put them up 33-27 with 2:33 left before halftime.
