TUCSON, Arizona (Ticker) -- For nearly 18 minutes, UCLA hung with top-ranked Arizona. For the next five minutes, everything fell apart - and it got worse.
Freshman Andre Iguodala led a balanced attack with a season-high 18 points as the Wildcats manhandled their Pac-10 Conference rival, 106-70, for their 14th victory in 15 games.
"Andre Iguodala did a really good job off the bench," Arizona coach Lute Olson said. "He is getting better and better every day. His shot looks really good and he is getting his shot off a lot quicker. He is making plays and it was great to see him do the job that he did for us tonight."
"Coach O drills it in our head to practice hard and we have been," Iguodala said. "And it paid off tonight. It flowed well. This may have been our best game of the whole season because everybody played a lot and scored and after the game everybody was happy."
Arizona led just 35-32 after a layup by UCLA's Dijon Thompson with 2:21 left in the first half. But the Wildcats closed the half on a 10-2 run, then opened the second half on a 16-0 burst to take a 61-34 advantage on a jumper by Salim Stoudamire with 16:26 remaining.
"We had a great second half," Olson said. "We came out in the second half with great intensity and enthusiasm. We made a lot of things happen as a result of playing good defense. We scored a lot of points off of their turnovers. We had about 32 or 33 points off the breaks."
UCLA committed 19 turnovers - 10 more than Arizona.
Stoudamire and Jason Gardner scored 14 points apiece and Rick Anderson and freshman Hassan Adams 12 each for the Wildcats (19-2, 11-1), who led by as many as 39 points en route to maintaining their one-game edge over California atop the conference standings.
Andre Patterson scored 12 points and Jason Kapono 11 for UCLA, which has been outscored by a combined 71 points in its two games against Arizona this season. On January 18, the Wildcats handed the Bruins their worst defeat ever at Pauley Pavilion, 87-52.
"We know Arizona counts on vital spurts, especially here at home," Kapono said. "It's the spurt of death. We have been the victims of it four years in a row. Arizona definitely feeds off the crowd and they are well-coached."
UCLA (5-15, 2-9) has lost nine straight conference contests and 10 of its last 11 games overall.
"I think I'm out of the running for national and Pac-10 Coach of the Year," embattled Bruins coach Steve Lavin joked.
The Bruins, who lost at Arizona for the sixth straight time, are in danger of failing to qualify for the eight-team conference tournament. They are in ninth place, one game behind Washington.
"Our goal now is to keep improving and make it to the conference tournament and then it's a three-game single elimination," Lavin said. "We talked about it right after the game that we can still make the conference tournament, and with it being in Staples Center (in Los Angeles), we could still win it and get into the NCAA Tournament."
Arizona shot 49 percent (36-of-73) and limited UCLA to 43 percent (25-of-58). The Wildcats sank 12-of-23 3-pointers while the Bruins connected on just 3-of-12.
"I think Lavin is a good coach," Gardner said. "I don't know what the problem is - I'm not in their locker room. They've got a few games left before the end of the season, so maybe they'll get it going. I think they will."
