TUCSON, Ariz. -- Arizona heard all week about Gonzaga, how the Bulldogs were a big and talented team that could end the Wildcats' long home winning streak.
The Wildcats took it as a challenge, stood toe-to-toe with the Zags and pulled out a big non-conference win.
T.J. McConnell scored six of his 12 points in overtime, and No. 3 Arizona held on for a 66-63 victory over No. 9 Gonzaga after Byron Wesley air-balled the first of three missed free throws with 3.3 seconds left on Saturday.
"It was a mindset of kind of taking personally: What about Arizona, why not us?" said McConnell, who scored all of Arizona's points in overtime.
Arizona (8-0) rallied from a poor-shooting first half and a couple of deficits in the second half. McConnell, limited in the first half by foul trouble, was assertive in the extra period, leading the Wildcats to their 26th straight home win.
Brandon Ashley had 14 points for Arizona, which made 14 of 24 shots after halftime to win its 35th straight regular-season non-conference game.
"Our defense was very, very good and that's why we won," coach Sean Miller said.
Gonzaga (7-1) shot well inside, but went 4 for 17 from 3-point range and had two key turnovers late in overtime.
Wesley had a chance to tie the game after being fouled on a 3-pointer, but was well short on his first attempt and clanged away the other two.
Kyle Wiltjer led the Bulldogs with 15 points. Kevin Pangos had six assists, but was held to eight points on 3-of-10 shooting.
"We missed shots the last couple possessions and that hurt us," Gonzaga coach Mark Few said. "They were able to make a shot and that's what it came down to."
Arizona rolled Gonzaga in the round of 32 in last season's NCAA tournament, and the rematch was a marquee matchup of deep, talented teams butting heads in one of college basketball's best venues.
Arizona's forte has been defense, holding the Wildcats together when their offense has struggled.
Gonzaga, which won the NIT Season Tip-Off, has gotten to this point behind one of the nation's most efficient offenses.
Neither team did very much early on.
Wiltjer kicked off the game with an air ball on an open jumper, a prelude for what was a physical, don't-give-an-inch first half.
Arizona hit 9 of 27 shots in the first half, pulling even at 27-all after Ashley scored five quick points and found Elliott Pitts for a kick-out 3-pointer.
"We had a dismal performance in the first half on offense," Miller said. "It was our great defense that tied the game."
Gonzaga struggled early on against Arizona's all-over pressure. It found a rhythm for a short stint to go up seven, and then struggled again to finish the first half at 9 of 29 from the field.
The second half was completely different, with the teams trading athletic plays and big shots instead of clanks.
Gonzaga pushed the lead to 60-54 on a putback by Wiltjer, but Arizona fought back, tying it on a jumper by Ashley with 1:25 left.
Wiltjer had a chance to win it at the end of regulation, but his turning 3-pointer from the corner just missed.
Wesley's errant free throws at the end also were quite costly. He missed the final one on purpose so the Bulldogs could get another shot, but Arizona grabbed the rebound and the game.
"I'm going to tell him (Wesley) I have 100 percent trust and confidence in him the next time he's up there," Few said. "He's been a great player for us this year and he's a tough play, and I wouldn't want anyone else on the line than him."
Pangos came into the game with reputation as one of the nation's best point guards, averaging 12.3 points on 58 percent shooting with nearly six assists per game. Arizona all but shut him down by rotating McConnell, Gabe York, Pitts and Rondae Hollis-Jefferson on him. Pangos went 1 for 3 from 3-point range.
