Joel Embiid starred as the Philadelphia 76ers extended their winning streak to six games by topping Eastern Conference hopefuls the Chicago Bulls 114-105 in the NBA on Saturday.

Embiid – last season's MVP runner-up – posted 30 points, 15 rebounds, three assists and two blocks to fuel the in-form 76ers on the road in Chicago.

He also made four of five three-pointers as the 76ers finished 50 per cent from beyond the arc, while Furkan Korkmaz (25 points) matched a career high with seven made threes.

It was a memorable night for 76ers head coach Doc Rivers, who celebrated his 1,000th career victory – the 10th NBA coach to achieve the feat.

Eastern Conference leaders the 76ers (8-2) have won eight of their first 10 games for the first time since a 10-0 start in 2000-01.

Doncic on the buzzer

Luka Doncic hit a buzzer-beating three-pointer as the Dallas Mavericks topped the Boston Celtics 107-104. Doncic finished with 33 points.

The Denver Nuggets edged the lowly Houston Rockets 95-94 behind reigning MVP Nikola Jokic. Along with 28 points and 14 rebounds, Jokic also made the crucial block on Jae'Sean Tate's drive to the basket as time expired.

Kyle Lowry put up a triple-double of 20 points, 12 rebounds and 10 assists – the 19th of his career – to key the high-flying Miami Heat's 118-115 victory at home to the Utah Jazz. Donovan Mitchell's 37 points were not enough for the Jazz.

Westbrook headlines Lakers' woes

Without LeBron James (abdominal strain) and Anthony Davis (two points) only managing seven minutes, Russell Westbrook struggled in the 105-90 loss away to the Portland Trail Blazers. Westbrook made just one of 13 shots for eight points, while he turned the ball over on six occasions.
