LEXINGTON, Ky. -- Only briefly did UCLA appear vulnerable against top-ranked Kentucky. The Wildcats have been one of the hardest teams to beat at home, but they didn't have an answer for UCLA.
The 11th-ranked Bruins made timely baskets and rebounds, a consistent combination that grabbed momentum and eventually the game from the Wildcats.
Isaac Hamilton scored 19 points, and UCLA beat Kentucky 97-92 on Saturday. The Bruins' victory marked their second upset of the top-ranked Wildcats in as many years. TJ Leaf added 17 points and 13 rebounds as the Bruins shot 53 percent from the field.
More impressively, the Bruins won in their first-ever visit to storied Rupp Arena, where the Wildcats had won 42 straight coming in and 89 percent overall.
"I don't think there was anything about them today that was a feeling-out process," said UCLA coach Steve Alford, whose team regained the lead for good late in the first half. "We talk about, 'Don't go in and jab around the ring to see if you belong. You're 8-0. You're playing well. Trust that you belong.' That was the key thing that guys did from the tip."
The Bruins (9-0), who entered as the nation's third-ranked scoring team, matched their season scoring average to win this showdown of college basketball's winningest schools. Kentucky (7-1) cut a 14-point, second-half deficit to 95-92 on Derek Willis' 3-pointer with 8.3 seconds remaining, but Bryce Alford's two free throws with 7.4 left sealed the victory.
Besides hitting 35 of 66 from the field, UCLA outrebounded Kentucky 41-38 and limited the Wildcats to 41 percent shooting. It was the most points scored against a Kentucky team coached by John Calipari, who credited the Bruins for controlling the tempo against his talented freshmen.
"This is a lesson for us," said Calipari, whose team had posted three consecutive 100-point efforts coming in. "We didn't have the energy. I had to call a timeout a minute into the game. I mean, just wasn't the same team. There are great lessons out of this. I wish we would have come back and won. ... But sometimes you need to get hit on the chin, especially at home."
THE BIG PICTURE
UCLA: The key point for the Bruins came seconds before halftime, when Ball's 3-pointer provided a 49-45 lead to cap a 58 percent shooting half. "I had the shot and I took it," said the freshman, who finished just 2-of-8 from long range and 5-of-12 overall. "Coach Alford says to never hesitate. I wasn't hitting the whole game, but in the big moments, I'm going to come through. I put it up and it went in. It was a good shot and a good way to go into halftime."
The Bruins followed with a 9-2 run to open the second half for a 58-47 lead and kept their poise throughout with another team-wide effort that included 18 assists, six off their season average.
Kentucky: The Wildcats overcame a 3-of-9 start to reach 50 percent from the field in the first half before a 1-of-8 spell to close the opening 20 minutes. They never got it going in the second half despite making 5 of 13 from long range. What bothered them most were the defensive breakdowns that allowed UCLA to get good looks.
"We weren't focused like we usually are," Monk said. "We have to be focused and ready to play day in and day out. If not, we'll get beat just like this."
BEATING NO. 1s
This was UCLA's 12th victory over a No. 1 team, one behind all-time leader North Carolina.
The Bruins' second straight win over Kentucky figures to move them into the Top 10. Kentucky should tumble a few spots, though not many.
MAYBE NEXT TIME
Kentucky didn't hold a morning shootaround because of the midday start, and Calipari wondered if he should have after looking at the stat sheet.
"I just felt maybe they were mature enough to do this," he said. "I'm learning about this team."
