Team USA

Kevin Durant's  bid to join Carmelo Anthony  as the only other basketball  player to win three straight Olympic gold medals is still alive after another stunning display against Australia.

Durant had a game-high 23 points and nine rebounds as the U.S. defeated Australia 97-78.

The USA's all-time top-scorer was everywhere, stopping dunks, hitting threes, single-handedly putting down an early Australian uprising and now the States play for their 16th gold medal in Tokyo.

The USA's Sydney McLaughlin has set a new world record with a phenomenal run in the women's 400m hurdles final. The new Olympic champion broke her own world-best mark of 51.90, storming past compatriot Dalilah Muhammad down the home straight to win the Olympic gold medal in 51.46 seconds.

Muhammad - the Rio 2016 Olympic champion - took silver, going under 52 seconds in a time that also broke the former world record (51.58). Femke Bol of the Netherlands finished third in a new European record of 52.03.

Three-time Olympic medallist James and nine of the players from the successful 2016 campaign in Rio were included on the list announced by USA Basketball on Monday.

Should the Los Angeles Lakers star make the final 12-man roster, he will join Carmelo Anthony as the second player to represent Team USA at four separate Games.

Kevin Durant and Klay Thompson won gold in Brazil four years ago and have made the cut despite being yet to play a minute in the NBA this season due to respective Achilles and knee injuries.

USA coach Michelle French admitted that her players have consistently talked about how incredibly the fan’s support has been.

“When you’re coming in for a game you never know if anyone will be out there cheering for you.

“The supporters always motivate the players when they start chanting their names.

“We tend to feed off the energy of the crowd so it’s been an absolutely fantastic experience so far playing in front of the local people and we look forward to the next game,” French said.

As if Olympic sensation Simone Biles didn't already have plenty of reasons to smile -- like maybe her four gold medals and one bronze -- she's got another reason now.

Actor Zac Efron -- fulfilling teenage crush goals everywhere -- popped over to Rio to find Biles and plant a surprise smacker on her.

"He kissed me on the cheek, just letting y'all know," Biles shared in a tweet.

As the opening ceremonies aired Friday night on NBC, Ashton Kutcher and Mila Kuniscouldn't help but show a little team spirit on social media.

While posing arm-and-arm, the Hollywood couple showed who they will be rooting for in the next two weeks.
