Antonio Hudson scored 20 points and grabbed nine rebounds as the Tigers (7-1) captured their first win over a No. 1-ranked team since 1978. LSU's last triumph over the nation's best team was a 95-94 overtime win over Kentucky.
"I couldn't hear myself talk it's so loud out there," LSU head coach John Brady said. "What a great place to play basketball."
Jaime Lloreda notched a double-double pouring on 19 points and 13 rebounds while shooting 6-of-10 from the floor and 7-of-10 from the charity stripe.
"That is the game I was wanting every since I signed with LSU," Lloreda said.
Ronald Dupree was the only other Tiger in double figures with 12 points and nine rebounds.
It marked three consecutive loss for Arizona in the capital city. The Wildcats lost a 92-82 decision in 1990. Ten years later, Olsen's No. 4-ranked club was blasted 86-60 in their last visit to the assembly center.
"We can play with any team in the country," Hudson said. "The media said they are the best team in the country and we just beat them."
The Tigers held a 32-26 halftime lead and led by as many as 15 points in the second half before the Wildcats (5-1) made a furious run in the game's waning moments.
"They had opportunities not to try and finish the game," Brady said. "But like any great team, which they are, and like any No. 1-ranked team, which they deserve to be, they played hard until the finish."
Olsen felt his team did not play with the same fire it did in the last six minutes of the contest.
"We were a different team the last five to six minutes than we were in the first 34 or 35. That's hard to explain, said Olsen. "We have to play with that sense of urgency all the time."
Arizona, a team which averages 92 points a game this season, was reduced to a season-low 26 points in the first half. A 34-point first half effort in a 73-70 win over Texas was the previous low.
"We didn't hit s—t, plain and simple," Rick Anderson said. "When you don't hit anything, you can't win. It was kind of a weird night."
Anderson had a few more colorful metaphors for the LSU crowd, especially when he exited the game following his fifth foul with 6:53 remaining in the game.
The Tigers led 61-53 with 3:04 remaining in regulation when Arizona began to rally. Hassan Adams converted a layup and picked up the foul, finishing the three-point play. Channing Frye tacked on a free throw cutting LSU's lead to three points with 2:11 left.
"I kept telling our team my team they were going to make a run at us at some point and they did," Brady said. "But the toughness in the defensive effort of our team tonight was really good."
LSU's Ronald Dupree answered Adams three-point play, with a deuce and a free throw on the other end, raising the Tigers' lead back to six, 64-58.
The Wildcats' Salim Stoudamire hit a running jump shot with 1:56 left in the game making it a 64-60 contest. Hudson scored his 20th point of the game on a jumper with 1:22 remaining, giving LSU a six point lead.
The Tigers would not score again.
In a strange chain of events, LSU was forced to call its last timeout with 8:55 left in the second half and it came back to haunt the Tigers near the end.
In an effort to save a loose ball, Dupree leaped out of bounds, made the grab and - doing his best Chris Webber impression - quickly spun and called a 20-second timeout. An indirect technic
