TUCSON, Arizona (Ticker) -- Arizona's opener showed it was worthy of the No. 1 ranking.
Freshman Hassan Adams scored 22 points and Rick Anderson added 14 and the top-ranked Wildcats poured it on for a 107-68 rout of No. 23 Western Kentucky in the season opener for both schools.
Arizona (1-0) placed seven players in double figures and never trailed after spotting Western Kentucky the game's first basket. The Wildcats responded with an 18-2 run and built a 14-point cushion on Adams' dunk with 13:31 left in the first half.
"With our intensity on defense, we're going to have a lot of big runs like that this season," Arizona coach Lute Olson said.
Anderson, who did all his scoring in the first half, nailed two 3-pointers and Luke Walton added one in an 18-0 run that opened a 51-19 lead with 1:40 remaining. Adams had a basket to cap the burst.
Walton, Jason Gardner and Will Bynum each had 12 points and Channing Frye netted 10 for Arizona, which improved to 17-3 in openers under Olson.
"We just have to have destroy teams, top 10 or whatever," Adams said. "That's our goals this season - just destroy teams, win the Pac-10 and go all the way to New Orleans (and the Final Four)."
The Wildcats used full-court pressure and waves of substitutions to turn up the heat on Western Kentucky, which committed 28 turnovers. Nine Wildcats played at least 17 minutes.
"We put a lot of pressure on them and what it does, it not only wears them down physically, it wears them down mentally," Olson said. "Mentally seeing new guys coming at them all the time wore them down."
"Arizona is another solar system from us as far as athleticism and overall talent," Hilltoppers coach Dennis Felton said. "We're not in the same area code as Arizona, but I don't know if you can find five more teams in the whole country who can be."
Western Kentucky was led by David Boyden, who scored 26 points. The Hilltoppers played without All-American center Chris Marcus, who is sidelined with foot problems.
Arizona shot 55 percent in the first half and was even better in the second, clicking at 57 percent (20-of-35). Anderson had six straight points in the early 18-2 run and made 6-of-8 shots in the first half.
"It was just adrenaline," Anderson said. "I had it, man, so I had to just keep shooting. We saw that tentativeness in their eyes and we just have to keep the pressure on. And we did that perfectly."
The Wildcats' scoring was so balanced that Gardner, the Preseason Pac-10 Player of the Year, did not score his first basket until just under four minutes left in the first half. Even walk-on Jason Ranne made two free throws late in the game.
The balance has resulted in intense competition for playing time. And Adams realizes his big effort guarantees nothing.
"I just have to keep working hard just to get my minutes," Adams said. "It's competitive just to get minutes on this team. Luke, Jason, Ricky, we all go at each other so hard in practice that it makes it easier in games.
Frye contributed nine rebounds and Dennis Latimore and freshman Andre Iguodala each added six as the Wildcats held a 42-25 edge on the glass. Iguodala was the seventh Arizona player in double figures with 10 points.
Todor Pandov scored 12 points for Western Kentucky, which shot just 36 percent (9-of-25) in the first half. The Hilltopppers also made just 9-of-20 foul shots.
