Aussie Ben Simmons scores 19 points in Philadelphia's win against Atlanta.

Ben Simmons has played another big role as the Philadelphia 76ers beat the Atlanta Hawks 119-109, claiming their fourth win in their past five NBA games.

Following his career-high 24 points against the Houston Rockets, the young Australian scored 19 points and grabbed 13 rebounds while also dishing out nine assists as the improving 76ers levelled their season record at 4-4 with their first home win.

Centre Joel Embiid continued his emerging combination with Simmons, adding 21 points, 12 rebounds and six assists.

Simmons, the No. 1 overall pick in the 2016 draft, has lived up to his top billing in his rookie year. He has scored in double figures in every game and again flirted with a triple-double. He sealed the win with a thunderous slam in the final minute.

Simmons keeps saying he can play better - but the 21-year-old Australian has already joined Oscar Robertson as the only players in NBA history with 100 points, 50 rebounds and 40 assists in his first six games.

The Sixers came out fired up like a team coming off big wins on the road at Dallas and Houston and hit their first six 3s of the game.

They led 25-8 and had everything going right as they went for their first win at home this season.

In coach Brett Brown's five seasons, the Sixers had not been at .500 since they were 5-5 on November 15, 2013.

They started that season 3-0 and lost the opener - and many more after that - in each successive season.

Simmons put an exclamation point on the win with a thunderous slam in the final minute that had the fans standing and chanting "Trust the Process!"

Dennis Schroder scored 25 points and Taurean Prince had 17 for the woeful Hawks.

Meanwhile,  Perth Wildcats centre Matt Knight has been ruled out of Friday night's NBL clash with the Sydney Kings after copping another hit to the head.

Knight almost retired at the end of last season because of concussion issues, and he has been struck in the head three times already this season.

The 32-year-old's latest knock came at team training on Monday when he copped an accidental elbow and the Wildcats say they will rest Knight against the Kings as a precaution.
