Kevin Durant and Bradley Beal each scored 17 points as the Americans took control from the outset, after shock losses to Nigeria and Australia in Las Vegas.

The Americans shot at 51 per cent, scored 33 first-quarter points to get off and running and beat Argentina for the 10th consecutive time since a loss at the 2004 Athens Olympics.

Damian Lillard scored 13 points and Bam Adebayo finished with 12 points, five assists and five rebounds for the US.

"Just really locked in," Adebayo said.

Luis Scola, set to play in the Olympics for a fifth time, scored 16 points in 19 minutes for Argentina. Nicolas Laprovittola scored 13, Facundo Campazzo had 12 and Gabriel Deck added 10.

The US played with only eight members of the Olympic team. Jayson Tatum was held out with right knee soreness and will be day-to-day going forward, USA Basketball said.

The Americans also will be without Khris Middleton, Jrue Holiday and Devin Booker until at least this weekend because of the NBA Finals.

The back-to-back losses to start the US team's stay in Las Vegas raised the possibility that the Americans might lose three in a row with NBA players for the first time.

If those thoughts truly existed, they didn't last for long.

It was 15-4 before the game was even 3 1/2 minutes old, the lead was as much as 17 later in the opening quarter - the biggest leads for the Americans in the first two games were 10 against Nigeria and 11 against Australia - and the outcome was never really in doubt.

The Americans held a 58-42 lead at the half when Durant beat the buzzer with an 18-footer, a shot that Draymond Green was celebrating before the ball even swished through the net.

"We're not going to make shots all the time," Durant said in a televised halftime interview. "But if we continue to guard the way we are, it'll start to turn for us on offense.

"When we keep the ball in front and we get stops and rebounds, then we pretty much can play with a clean slate on the offensive side of the ball."
