The USA reaffirmed their status as Olympic favourites with a 78-60 win over world champions Serbia and Montenegro in Belgrade.
Allan Iverson scored nine points for the USA
After losing to Italy and beating Germany by just three points in the last week, the victory was welcome.
The visitors trailed 9-4 early on in front of a passionate 16,245 home crowd, but recovered to lead 42-26 at half-time.
Captain Tim Duncan led the US with 16 points, while LeBron James scored 11.
"I am pleased with tonight's performance but we can still improve in every aspect of our game," said US coach Larry Brown.
"We need to play tighter defense and improve our execution in offense.
"This is a young team still learning. We know they will be a much better team in Athens."
Serbia and Montenegro coach Zeljko Obradovic said: "Our crowd had high hopes after their performances in Germany but we knew it would be a different ball game tonight.
"They were always individually very strong and now they have started to blend together and will improve with every game."
