NBA champion Patty Mills has steered the Boomers to a come-from-behind win over Team USA – their first ever win over the basketball superpower – at Marvel Stadium on Saturday.

Putting the controversy over complaints about misleading advertising on the backburner, the home side turned it on to triumph 98-94 in front of the the biggest crowd in Australian basketball history.

An attendance of 52,079 was announced two days after 51,218 watched Team USA take out a 102-86 victory under the closed roof.

On Saturday the Americans followed a similar script to the first game, rallying out of a tough contest to build a 10-point lead midway through the third quarter.

But Australia closed the term on a 20-8 run – Mills recording eight points and two assists in the push – to hold a two-point lead heading into the final 10 minutes of the game.

The margin jumped out to six points early in the fourth as Joe Ingles and Aron Baynes went to work but Boston Celtics duo Kemba Walker and Jaylen Brown returned fire, briefly sending Team USA ahead.

Mills drew a charge on Myles Turner, Ingles hit his first triple of the game and then Mills banked in a three of his own to force legendary coach Gregg Popovich into a timeout, the Americans down four points with three minutes remaining.

Mills caught fire again to score 10 Australian points in a row late in the fourth quarter, finishing with an astonishing 30 points.

The 31-year-old's effort left his NBA coach at the San Antonio Spurs stunned by the result – but not surprised.

"Like I said last game, Patty's a pain in the arse," Popovich told reporters after the defeat, the team's first loss with a full NBA squad since 2006.

NBA champion Andrew Bogut finished with 16 points on 7-8 shooting, nine rebounds and four assists for the Boomers, while Ingles had 15 points and seven assists.

"This is huge for us," said Bogut, who was distraught after missing out on a bronze medal at the Rio Olympics three years ago.

"It's a friendly so we want to keep it in context, but we did make history tonight as the first senior men's Australian team to beat an American team.

"This is a special group of guys that really like playing for their national team and are proud to put on that jersey and we've got a group who feel like we can beat anybody in the world."

The victory concluded mixed preparations for the Basketball World Cup on a high note after coach Andrej Lemanis saw Philadelphia 76ers teammates Ben Simmons and Jonah Bolden withdraw from selection.

Bolden left the team over a reported dispute about playing time, while his exit came after young prospect Xavier Cooks was forced out when he tore his meniscus at training.

Game two on Saturday also marked a positive turnaround for Nick Kay, the NBL forward who struggled against Team USA on Thursday.

He finished with seven points as the Boomers outscored the Americans by 18 points while he was on the court.

Next up: Basketball World Cup

While Team USA will travel to Sydney to face Canada, Lemanis and the Boomers will look towards China for the World Cup beginning on August 31.

Australia have never won a medal at the Olympics or a World Cup, coming closest at the Rio 2016 Olympics where they were edged out by Spain for the bronze medal.

The Boomers will face Lithuania, Senegal and Canada in a tight first round, with the top two teams progressing to a second group stage.
