The UCLA Bruins played an impressive first half. They started off by scoring the first four points of the game. Arizona came right back and took a 15-12 lead with about 13 minutes to go in the first half.
Aaron Holiday's jumper with 12:43 to go in the half started UCLA on a big 19-6 run which would put the Bruins up by 10 points and make the score 31-21.
But, it was Isaac Hamilton who was the star of the first half with 15 points. He hit a jumper with about three minutes to go in the half which gave UCLA an 11-point lead which was its biggest lead of the game.
The Wildcats was able to cut it to as few as seven before UCLA made it a ten-point lead as the teams went into the locker rooms.
After the break, UCLA maintained their lead for most of the second half.
The Bruins still led by ten with sixteen minutes left. But Arizona guard Allonzo Trier hit a pair of free throws to make it 49-41 UCLA and that was the start of UCLA's collapse.
By the time Trier hit his next two free throws with about eight and half minutes left, the Bruins' lead was down to three points. A minute later, Ryan Anderson put Arizona out in front for the first time in almost 25 minutes.
In the final six and a half minutes, the Wildcats outscored UCLA 20-14 to win by a score of 81-75.
It was a classic collapse by a Steve Alford-coached team. Thomas Welsh and Tony Parker both fouled out and the bench depth just wasn't there.
Isaac Hamilton added nine points in the second half to lead all scorers with 24 points while Allonzo Trier led Arizona with 18.
The loss drops the Bruins to 4-7 in the Pac-12. The Bruins' next game is on Sunday in Tempe against Arizona State.
Go Bruins.
