NBA playoffs: Spectacular Luka Doncic buzzer-beater lifts Mavericks over Clippers

Luka Doncic's three-pointer at the buzzer in overtime has lifted Dallas Mavericks to a 135-133 comeback victory over Los Angeles Clippers in the NBA bubble near Orlando.

Slovenian Doncic shook off the effects of a sprained left ankle and recorded his second consecutive triple-double with 43 points, 17 rebounds and 13 assists. He carried the Mavericks to the win, despite playing without star centre Kristaps Porzingis (knee).

Trey Burke added 25 points and Tim Hardaway Jnr scored 19 of his 21 in the second half for the Mavericks, who tied the Western Conference first-round series at 2-2. Seth Curry chipped in 15 points.

Lou Williams had 36 points and Kawhi Leonard finished with 32 points for the Clippers, who blew a 21-point first half lead. Ivica Zubac contributed 15 points, while Paul George managed just nine points on 3-of-14 shooting. He scored two points in the second half.

In the second Western Conference clash of the day, Donovan Mitchell scored 51 points and dished out seven assists to help Utah Jazz outlast Denver Nuggets for a 129-127 win to claim a 3-1 lead in their first-round series.

Mitchell posted his second 50-point game in the series, becoming just the third NBA player to score 50 points twice in the same playoff series, joining Michael Jordan and Allen Iverson.

Mike Conley scored 26 points and Jordan Clarkson added 24 off the bench for the Jazz. Rudy Gobert chipped in 17 points and 11 rebounds.

Jamal Murray exploded for 50 points, 11 rebounds and seven assists to lead Denver. Nikola Jokic added 29 points, seven rebounds and six assists in the loss.

In the Eastern Conference, Norman Powell scored a career playoff-high 29 points, as Toronto Raptors completed a four-game sweep of undermanned Brooklyn Nets in their first-round series with a 150-122 victory.

Serge Ibaka added a playoff career-best 27 points off the bench and grabbed 15 rebounds for the Raptors, who swept a best-of-seven playoff series for the first time in their 25-year franchise history.

Toronto played most of the game without guard Kyle Lowry, who had two points and three assists in nine minutes. With about three minutes to play in the first quarter, Lowry left the court after twisting his ankle and did not return.

The Raptors, who set a franchise record for points in a playoff game, will play Boston Celtics in the Eastern Conference semi-finals, after the Celtics completed a four-game sweep of the Philadelphia 76ers.

The Celtics rode Kemba Walker's game-high 32 points, and a 14-point run bridging the third and fourth quarters to a 110-106 victory.
