TUCSON, Ariz. (AP)Â - Oumar Ballo scored 16 points, Azuolas Tubelis had a double-double and No. 11 Arizona withstood a late rally to end No. 5 UCLA's 14-game winning streak with a 58-52 victory on Saturday.
Arizona has won three straight meetings against UCLA dating back to last season and three in a row when UCLA is ranked in the Top 5.
Head coach Tommy Lloyd is 10-3 against Top 25 opponents and 3-0 against Top 5 opponent, the only coach in the last 25 years to win his first three games against Top 5 teams. The win was also the 50th of Lloyd's career, the fastest a Pac-12 coach has ever reached 50 wins and the eighth fastest in NCAA history.
The 58 points are the fewest the Wildcats have scored under Lloyd and it's the first time Arizona has won a game while scoring less than 60 since Feb. 21, 2015 when they scored 57 against UCLA.
The Wildcats (17-3, 5-3 Pac-12) appeared to be cruising to their biggest win of the season, taking a 56-44 lead on Ballo's alley-oop dunk with 2:07 left.
The Bruins (17-3, 8-1) fought back, creating four straight turnovers to pull within 56-52. UCLA then blocked consecutive shots - one after a review waved off goaltending - but couldn't convert on two shots of its own.
Arizona's Pelle Larsson hit two free throws with 0.9 seconds to close it out. Tubelis triggered an 11-3 run to give Arizona a 10-point lead early in the second half, finishing with 14 points and 10 rebounds.
UCLA matched its longest winning streak since 2007-08 on Thursday by pulling away late to beat Arizona State 74-62. The Bruins had a lot more trouble with Arizona, particularly at the offensive end.
UCLA shot 31% and went 4 of 20 from 3-point range to lose as a top-5 team at McKale Center for the second straight season. Tyger Campbell led the Bruins with 13 points and Jaime Jaquez Jr. added 12 with 11 rebounds.
On Saturday, the Bruins and Wildcats went toe to toe in the paint and perimeter, bodies bouncing off the floor in a physical, defensive afternoon. The Bruins banged on Ballo and Tubelis in the post on every touch, creating numerous close-range misses - and plenty of fouls.
UCLA backup big man Kenneth Nwuba had four fouls in the first half and Ballo made 8 of 10 free throws to score 12 first-half points.
Arizona hit 7 of 23 shots and was the better-shooting team, taking a 26-23 halftime lead.
HONOR
 Arizona formally inducted Ernie McCray (1957-60) into the Ring of Honor in the McKale Center. McCray still holds the UA single-game scoring mark (46) and ranks in the top 10 in program history for career scoring and rebounding.
BIG PICTURE
UCLA: Pushed the Wildcats around early and created havoc with their defensive pressure late. In between, the Bruins didn't hit enough shots to leave the desert with a win.
Arizona: Weathered UCLA's bumping and banging in the first half, then withstood a furious rally to earn the type of win that should move it back into the top 10.
UP NEXT
UCLA: At rival USC on Thursday.
Arizona: Plays at Washington State on Thursday.
POSTGAME MEDIA

UCLA Head Coach Mick Cronin
On UCLA's defense in the game:
"I still think our defense was really bad. I don't think we played the way we play at UCLA. Usually we try to play with heart and intestinal fortitude. I don't think we played by the way. So I think we're offensive sensitive all day. So I'm not impressed with our defense at all today. I couldn't care less what the final score. I didn't think we played hard to the win this game."
On David Singleton's struggles:
"...when you struggle offensively, something on the other team's defense causes it. Even if it's open shots, they have you sped up just enough, rattled just enough. So I think you have to give the other team credit."
Â
On the late defensive effort that forced Arizona into turnovers:
"It shows you what you're capable of when you play with your heart and intestinal fortitude. You start playing with your mind -Â what you're getting if you only put it in your mind. Your mind is on your miss shots. Instead of your mind needs to be on your effort. You can control your effort. Every day when you wake up. You can control every play. Gotta make things happen. We can't get out. You can't get on a break - Look, it's hard to score. It's late. It mean it's a grind. The grind is here. Ask (Arizona), it's hard to score on us.You have to get in transition. We had two guys that got deflections in the first half - how are you going to get in transition..."
