With their Olympics opener scheduled for Sunday against the host Chinese, Kobe Bryant, LeBron James and the rest of the team arrived amid near pandemonium after fans waited hours for a glimpse of their basketball heroes. Later, the players held a team meeting before deciding to head to the Olympic village to take in the sights.

"It's a little overwhelming that it's really here - the reality that we're here," said Colangelo, the managing director of USA Basketball. 

The Los Angeles Lakers guard waved and smiled, looking pleased and vaguely amused by the display. Players left Beijing's airport by a side door and boarded a bus in a secure VIP area before driving into the city.

"I try to see American players every time they come to China, but this time is the most special because of the Olympics," said Manny Chen, a spikey-haired college student dressed in a USA jersey with Bryant's name it.

"Unsatisfactory performance in  87-76 win against Australia"

They couldn't shoot and occasionally didn't defend. Definitely a performance the Americans should be relieved came before they got to Beijing.

Undefeated, but no longer unchallenged, the U.S. Olympic basketball team wrapped up its exhibition schedule with its toughest test, pulling away to beat Australia 87-76 Tuesday night.

The United States led by only four points nearly halfway through the third quarter and was up by seven midway through the fourth against an Australian team that was resting its best player, Milwaukee Bucks center Andrew Bogut.

The U.S. players still feel like gold medal favorites, but they hardly looked like gold medal locks during this shaky outing.

"Nothing alarming for us. It's alarming when you lose," Dwyane Wade said.

"We're still growing. We're still going to get better as each game goes on, but I think tonight we learned something."

The Americans relied on an aggressive defensive effort to overcome a horrendous night from 3-point range and the free throw line, the same areas that proved costly in their semifinal loss to Greece in the world championships two years ago.

Wade scored 22 points and LeBron James had 16 for the Americans, who finished 3-of-18 from behind the arc and 20-of-33 (61 percent) at the foul line.

The U.S. team won two blowouts in Macau but found things much more difficult here, starting with an 89-68 victory over Russia on Sunday.

"The last two games the ball has been sticking a little bit, so we have to get back to looking like the first game where everybody was touching the ball and we were playing like we should," point guard Jason Kidd said. "We're too talented of a team to take tough shots because there's always going to be someone open."

Patrick Mills and Chris Anstey, who had a first-half altercation with Wade, each scored 13 points for Australia.

"In the third quarter they knocked down some big shots and I think that got them back in the ball game," Kobe Bryant said. "And for us, we have to understand that that's going to happen from time to time and it's important to keep our poise, keep our composure and buckle down."

The U.S. team seemed in control after allowing one basket in the final 5 1/2 minutes of the first half to open a 44-29 lead. But the Americans left that defensive intensity in the locker room, allowing a number of open 3-pointers and uncontested drives to the basket.

"We came out lazy," Wade said.

The Australians outscored the Americans 13-2 to open the third quarter, pulling to 46-42 on David Barlow's layup with 6:52 remaining in the period.

"We just broke down. We gambled a couple of times and allowed them to make the extra pass," James said. "We can't have those types of mental breakdowns because these teams can really shoot the ball."

Michael Redd and Wade had layups to open the scoring in the fourth, pushing the U.S. lead to 69-55. Australia scored nine of the next 11 points to pull within seven with still half the period left, making the upset seem possible. The crowd even got behind the Australians, loudly booing a call that overruled what seemed to be a potential three-point play for them on an offensive rebound.

The Americans got their running game going again, and Wade had some easy baskets as they pulled away for their closest victory. The win over Russia was the previous closest game for the Americans, who came in averaging 110.8 points and shooting 64.2 percent from the field.

Bryant scored 13 points and Carmelo Anthony had 12 points and 10 rebounds for the United States, which faces host China on Sunday in its Olympic opener.

Bogut, the No. 1 pick in the 2005 draft, wanted more time to rest a sore right ankle that has been bothering him, but said he expects to be ready by the opener against Croatia on Sunday.

The Australians threw a scare into defending gold medalist Argentina in an earlier friendly, building a 19-point lead in the third quarter before losing 95-90.

They started well in this game, with Mills fearlessly driving to the basket and helping Australia lead by four a few times in the first quarter before the Americans rallied to grab a 22-19 lead. U.S. coach Mike Krzyzewski started the second quarter with a lineup of James, Bryant, Wade, Anthony and Deron Williams. Australia wasn't scared of that unit, with Wade and Anstey jawing after Anstey fouled Wade away the ball and the players got tangled when the U.S. guard got up.

"What they've done, and where you see them, can intimidate a lot of people," Anstey said. "I think to come into a game intimidated you've given up before you start, and we didn't feel like we did that tonight."

Australia cut it to 26-25 on David Andersen's basket with 5:36 remaining in the half, then the small unit's pressure defense set in and made it hard for the Australians to even take shots.

The Americans forced eight turnovers in the period led by James, who was all over the court coming up with steals and blocks. He scored eight straight points to make it 37-25, then swatted a shot into the seats about a minute later.

Australia finally ended its drought when Mills went all the way for a layup with 1:51 to go, but the Americans came back with a steal by James leading to his own bucket and were up 15 at the break.
