Miami , United States (AFP) – Toronto reserve Norman Powell scored 12 of his 24 points in the fourth quarter as the defending champion Raptors rallied to beat Brooklyn 104-99 Wednesday in their National Basketball Association (NBA) play-off series.

The Raptors took a commanding 2-0 lead in the best-of-seven Eastern Conference first-round clash being played in the league’s quarantine bubble in Orlando, Florida.

The Boston Celtics also seized a 2-0 lead in their Eastern Conference clash with Philadelphia, shrugging off the absence of injured Gordon Hayward to thrash the 76ers 128-101.

The Raptors, who had converted 22 three pointers in a game one blowout of the Nets, connected on just 25.7 per cent of their three-point attempts – and 43.7 per cent of shots overall – under heavy defensive pressure from a Nets team eager to even the series.

But turnovers proved crucial, with eight Toronto giveaways leading to six Nets points while 17 Brooklyn turnovers resulted in 23 points for the Raptors.

Brooklyn, trailing by three with 15 seconds remaining, had a chance to force overtime but an ill-timed pass on their final possession led to a final, decisive turnover forced by Toronto’s Kyle Lowry that sealed the win for the Raptors.

“We’ve been here before,” said Toronto’s Fred VanVleet, who delivered a double-double of 24 points and 10 assists. “You’ve just got to stick with it, weather the storm.”

Trailing 80-74 through three quarters, the Raptors opened the fourth on a 17-5 scoring run, taking their first lead since the second period on O G Anunoby’s dunk with nine minutes to play.

Staying present

Powell extended the lead to eight points with a driving dunk, and the Raptors held on.

“It’s just about focusing on what we’ve got to do, staying present, staying within yourself, and staying confident in your abilities and taking what the game has given you,” Powell said.

Lowry finished with 21 points and nine rebounds and Pascal Siakam added 19 points for the Raptors, who will try to take a 3-0 lead today.

The Nets’s hopes of battling back could be hindered by the departure from Orlando of Joe Harris, who scored 14 points with 15 rebounds, before leaving the campus for what the team called a “personal matter”.

Quarantine rules mean Harris will miss at least games three and four of the series.

Jayson Tatum was the star for Boston, scoring 33 points in a dominant victory over the 76ers.

Kemba Walker added 22 points and Jaylen Brown added 20 for a Celtics team that announced after their game one win that Hayward would be sidelined for several weeks with a sprained ankle.

Joel Embiid led the 76ers with 34 points and 10 rebounds.

In Western Conference action Donovan Mitchell scored 30 points and handed out eight assists for the Utah Jazz, who cruised to a 124-105 victory over the Denver Nuggets that knotted their series at one game apiece.

It was a sweet reversal for Mitchell, who scored 57 points in a game-one overtime loss to the Nuggets.

The Jazz seized control in the second quarter, using a 2-9 scoring run to open a 61-48 half-time lead.

French centre Rudy Gobert punctuated the half with a put-back dunk, and there were five minutes left to play in the fourth when Denver Coach Mike Malone started looking toward today’s game three, pulling starters Nikola Jokic and Jamal Murray.

Mitchell connected on 10 of 14 shots, including six of seven from three-point range.

Jordan Clarkson added 26 points off the bench, as the Jazz withstood 28-point performances from Jokic and Michael Porter.

After the bitter overtime defeat in game one, Mitchell wasn’t getting ahead of himself.

“At the end of the day, this is one game,” he said. “We did our job. We’ve got to get three more.”

Elsewhere, Luka Doncic had 28 points, eight rebounds and seven assists as the Dallas Mavericks posted a 127-114 win over the Los Angeles Clippers to level their opening round series at 1-1.
