Ben Simmons lights up NBA with superb career-best feat

Basketball fans have lit up social media with praise for Ben Simmons after the Aussie delivered a superb career-best against Cleveland.

Simmons put on a first half masterclass against the Cavaliers to set up a huge 141-94 victory for the Sixers.

The Philadelphia ace's blistering start saw him notch a career-high 26 first half points, including the second successful three-pointer of his professional career.

Simmons finished with a career-high 34 points in 26 minutes of action on court, before he was given a well deserved rest on the bench.

His previous record was 32 points.

The Aussie's incredible numbers had fans in awe on social media but unsurprisingly, it was the Aussie's new-found confidence from range that left the biggest impression.

Simmons got the game off to a thunderous start with an uncontested dunk before he lit up the court with his trademark dunks and drives to the basket.

He recorded 14 points to represent a team season-high in the first quarter and then got to a career-best 26 points before the main break.

By the end of the game the All-Star added seven assists, three rebounds, two steals and two blocks to his stat sheet in just 26 minutes.

He was 12 of 14 from the field, including his lone three-point attempt and even a mid-range jumper, and nine of 12 from the free-throw line.

With three minutes 45 seconds remaining in the second quarter, the Australian star took an uncontested catch-and-shoot three-pointer from the left wing and found nothing but the bottom of the net to send the home crowd wild.

The 23-year-old then finished an alley-oop with a two-handed slam on the next possession.

Simmons has now made two shots from beyond the arc in his career, his first coming last month, after having gone none of 17 in his first two seasons in the league.

Philly led by a whopping 41 points at halftime, 77-36 - the most they have scored in any half this season and a franchise record advantage.

Mike Scott and Trey Burke chipped in with 21 points each as the Sixers (16-7) extended their unbeaten streak at home this season to 11.

Elsewhere on Saturday, Luka Doncic scored 28 points in 26 minutes while Kristaps Porzingis had 13 points and the 1,500th rebound of his career to help Dallas Mavericks rout New Orleans Pelicans 130-84.

Doncic also had nine assists and six rebounds but it was bench player Boban Marjanovic that had a night out.

The 7-foot 4-inch Serbian had season highs of 15 points and 16 rebounds.

Dallas led 64-52 at halftime - Doncic contributing 20 points while Marjanovic scored 11 points, nine in the second quarter alone - before a third-quarter blowout.

"(Marjanovic) did a great job," coach Rick Carlisle said.

The Pelicans didn't get within 10 points in the second half as they were outscored 40-14 in the third period.

The 46-point margin was two shy of Dallas' season high against Golden State.

Dallas have won five in a row to improve to 16-6. They are second in the western conference behind only the Los Angeles Lakers.

The 6-17 Pelicans have lost eight straight to sit only above the injury-stricken Warriors.

"A poorly played game, a poorly coached game," coach Alvin Gentry said.
