The Australian men's wheelchair basketball team have tasted their first Tokyo defeat in a heavy 66-38 loss to reigning Paralympic champions USA.
The Rollers stayed with the competition's big guns early, trailing just 17-15 at the end of the first quarter and even briefly levelled in the second stanza.
But the Americans, through Steve Serio and Jacob Williams piled on 10 unanswered points to break away for a 38-26 halftime lead.
That was pushed out to a 24-point margin by three-quarter time with the US in full control.
Williams top scored with 24 points on 10 of 19 shooting, including three 3-pointers, while Bill Latham's 13 points was best in the.faltering Aussie attack
Australia were bitterly disappointed by the scoreline, which came after Saturday's 64-53 win over Germany, who Team USA only managed to overcome by five points.
Despite the loss the Rollers remained top of Group B with three wins from four games thanks to a superior points differential.
The Americans, who lost to Great Britain also have a 3-1 record, while the Brits were shock losers against Germany.
