The United States fell to 0-2 in their exhibitions ahead of the Tokyo Olympics, losing to Australia 91-83 in Las Vegas.
The United States has now lost four of its past five games dating back to the 2019 World Cup.
"I thought we got better tonight," said Team USA coach Gregg Popovich, continuing his stance of emphasizing process over results. "After a short time together, there's a lot of things that have to be covered."
Damian Lillard had 22 points in the game for the United States.
"We walked into this game expecting to win," said Joe Ingles of the Utah Jazz, who had 17 points for Australia. "No disrespect to them, they're a hell of a team, obviously the guys they've got on their roster and Pop standing up there is always nice to see, but we came in here expecting to win the game and that's what we did."
