LAS VEGAS -- Team USA stabilized itself by putting together its most complete game of its Olympic preparation schedule, beating Argentina 108-80 on Tuesday night.

After back-to-back losses that saw the Americans struggle with offensive execution and defensive stamina, they showed more traction on both fronts 12 days before their Olympic opener in Tokyo.

"I thought we sustained our [stamina] pretty well," Team USA coach Gregg Popovich said. "Against Australia we competed well, rebounded, played defense, ran the floor and had good pace for a half and then it dissipated for a half. Tonight, we maintained that pretty much throughout the game. Hopefully that's a sign we're getting better."

Kevin Durant, the unquestioned engine of the national team's offense, had shown some rust after taking some time off following the Brooklyn Nets' seven-game series loss last month in the Eastern Conference semifinals. Like many of his Team USA teammates, he looked a little flat in the first two exhibitions, which both ended in unexpected defeat. He was just 10-of-26 shooting in those defeats to Nigeria and Australia.

Durant came out with a purpose Tuesday, swishing a 3-pointer on the game's first possession. He scored eight points in the first quarter and ended with 17 points on 6-of-9 shooting.

It was a similar story for Bradley Beal, who shot just 38% and averaged just seven points in the first two games while trying to regain rhythm. Beal made his first four shots, two of them 3-pointers, and ended with 17 points for easily his best game of the exhibitions.

"A sense of urgency is what we're kind of preaching," Beal said. "Today we got better, but there's still a lot more we can improve on. We're moving in the right direction."

Despite it being the second game of a back-to-back and a comfortable win, Popovich played Beal 30 of the game's 40 minutes in an attempt to help him round into form.

Popovich cited conditioning as a reason the Americans faded down the stretch in the two losses. After a heavy schedule for most of the players over the previous 12 months, players taking time to rest was expected after their seasons ended, but it seems to have contributed to the slow start.

Tuesday's game also featured a strong performance from Zach LaVine, a late addition to Team USA who has been building a case for more playing time this week. LaVine was in Popovich's starting lineup for the Jayson Tatum, who sat out to rest a sore knee, and made a statement with 15 points, five rebounds and three assists.

"Somebody's got to take Tatum's place," Popovich said. "So you choose one, simple as that."

LaVine, who has had more time off as the Chicago Bulls missed the playoffs, is one of the players who appears to be in better rhythm. He had a spectacular highlight dunk in the fourth quarter, rising over a defender and slamming it despite a foul.

It must be said the Argentinians, who came in ranked No. 4 in the world after taking the silver at the 2019 World Cup, were the weakest team the Americans have yet faced. They are 0-3 in the games at Mandalay Bay this week and are an older team. Former NBA player Luis Scola, who is 41, led them with 16 points.

A better test for Team USA's development will come Friday in a rematch with the Aussies. It will come after two days off to allow for some practice and film work.

"The last thing we want to do is overwork people to the point where we get injuries, but the first priority is we have to get back in shape," Popovich. "We're going to continue to work hard like we need to. ... Without the condition we can't get this done."
