Luka Doncic produced a stunning moment of magic to help the Dallas Mavericks outlast the Los Angeles Clippers 135-133 in overtime in Game 4 of their Western Conference first-round series.

With the Mavericks trailing 133-132 and staring at a 3-1 deficit in the NBA playoffs, Doncic called game as the reigning Rookie of the Year nailed a buzzer-beating three in OT on Sunday.

A game-time decision due to a left ankle injury, Doncic put fitness issues aside to see the Mavericks dramatically level the series at 2-2 in Orlando, Florida.

Doncic became the youngest player in NBA playoffs history to post a 40-point triple-double as he finished with 43 points, 17 rebounds and 13 assists.

It was the 21-year-old's second successive triple-double ahead of Game 5 against the Clippers at Walt Disney World Resort.

Kawhi Leonard's 32 points were not enough for the Clippers, while Lou Williams led the team's scorers with 36.

Defending champions the Toronto Raptors flexed their muscles in a 150-122 victory over the Brooklyn Nets as they recorded a sweep in the Eastern Conference first round.

Toronto's bench contributed 100 points, the most in any game since official starters began being tracked in 1970-71 – Norman Powell (29) and Serge Ibaka (27) leading the way.

The Raptors will face the Boston Celtics in the second round after the latter swept the Philadelphia 76ers 4-0 via a 110-106 success.

Mitchell makes history

Donovan Mitchell became the first player in NBA history to have two games with 50-plus points and five-plus assists in a single postseason as the Utah Jazz trumped the Denver Nuggets 129-127. Mitchell scored 18 of his 51 points in the fourth quarter to help the Jazz take a 3-1 lead in the Western Conference matchup.

Nuggets star Jamal Murray also put up 50 points in the losing effort. Murray and Mitchell are the first pair of players to register 50-plus points each in a non-overtime game since Wilt Chamberlain (63) and Elgin Baylor (51) in 1962, per STATS.

It was a huge night for the Raptors. Not only did they become the first team in postseason history to score 500-plus points in a series sweep (505), Toronto also became the first playoff franchise to have 150-plus points to cap a series whitewash.

Kemba Walker's 32 points and a double-double of 28 points and 15 rebounds from Jayson Tatum fuelled the Boston Celtics. Joel Embiid was a shining light for the 76ers with 30 points and 10 rebounds.

Sixers' swift exit, George struggles

It was a day to forget for the 76ers. It marked the first sweep at the hands of the Celtics in 15 playoff series meetings. Philadelphia have also failed to progress beyond the second round in three consecutive seasons.

The Jazz won but Joe Ingles was scoreless. Usually a threat from beyond the arc, Ingles missed all three of his three-point attempts. The Australian was also 0 for four from the field in 35 minutes.

Paul George's struggles continued against the Mavericks. He was just three of 14 from the floor and one of seven from beyond the arc for nine points in 45 minutes.

Doncic's Euro step

The Slovenian star was at his brilliant best, including this move to the rim.
