Sapporo, Japan ? Look out, world.

The United States routed Australia 113-73 Sunday, sending an unmistakable message to the FIBA world championships: This isn’t the team that proved an embarrassment in recent international competitions.

“We wanted to make a statement coming into the round of 16,” said forward Chris Bosh, who grabbed a game-high nine rebounds.

On a day that every American scored, Carmelo Anthony led the U.S. with 20 points while Joe Johnson added 18 and Dwyane Wade 15.

Granted, the Australians weren’t much of a test. They went 2-3 in group play and have few weapons beside Milwaukee Bucks center Andrew Bogut, who scored 20 points.

But the Americans made it look almost too easy, turning a tight game into a laugher by outscoring the Australians 32-6 in the second quarter.

Now the U.S. can look forward to its quarterfinal Wednesday night against Germany, another team with a star NBA center and a mostly anonymous supporting cast. Dirk Nowitzki of Dallas is third in tournament scoring, averaging 24.5 points.

Given the way the U.S. is playing, it might be more fair to make them face Bogut and Nowitzki together.

“I think our biggest opponent is ourselves right now,” Johnson said. “We’ve just got to keep our intensity up.”

Asked if the U.S. is unbeatable when its shots were falling, Johnson replied, “No doubt. When our shots are falling and when they’re not falling.”

Germany 78, Nigeria 77

Dirk Nowitzki scored 23 points and made the key defensive play in the closing seconds to lead Germany.

Nigeria pulled within one on free throws by Chamberlain Oguchi and Tunji Awojobi and had a chance to take the lead with seconds remaining. Ime Udoka drove for the basket, but Nowitzki tipped his shot and grabbed the rebound at the final buzzer.

France 68, Angola 62

Aymeric Jeanneau scored 16 points, including six free throws in the final 36 seconds, and France reached the quarterfinals for the first time in 43 years.

Greece 95, China 64

Theodoros Papaloukas had 19 points for Greece, which committed just three turnovers while forcing China (2-4) into 24.

Yao Ming, the 7-foot-5 center who plays for the Houston Rockets, had 10 points and eight rebounds for China.
