Philadelphia and Cleveland score important NBA wins

Joel Embiid top-scored with 42 points as the Philadelphia 76ers pulled away late for a 147-143 victory over the Indiana Pacers in an entertaining NBA game virtually devoid of defence.

Embiid made 11 of 16 field goals and all 19 free-throw attempts, while James Harden had 14 points, nine rebounds and 20 assists for the Sixers in Monday's game.

Tyrese Haliburton led the Pacers with 40 points and 16 assists in just their second home game since February 16.

Neither team led by more than six points through the first three quarters as they put up offensive numbers more closely resembling those of an All-Star Game. The Sixers finally took control with a late 10-0 run.

Philadelphia shot 62.5 per cent from the field and three-point range in the first half and finished the game at 58.5 per cent overall.

Donovan Mitchell scored 40 points and Lamar Stevens came off the bench to fuel Cleveland's fourth-quarter comeback with his hustle, leading the Cavaliers to a 118-114 win over the Boston Celtics, who lost their second overtime game in less than 24 hours.

Evan Mobley added 25 points and 16 rebounds for the Cavs, who improved to 7-0 in OT while avenging a loss in Boston five days ago.

Cleveland trailed by 14 entering the fourth quarter before Stevens, who only averages 12 minutes per game, entered and turned the match around.

Jaylen Brown scored 32 and Malcolm Brogdon 24 for the Celtics, who didn't arrive at their hotel in Cleveland until 2.30am after losing to the New York Knicks in double overtime on Sunday.

Damian Lillard had 31 points, 13 rebounds and 12 assists, securing his second triple-double of the season and third of his career before the end of the third quarter, as the Portland Trail Blazers beat the Detroit Pistons 110-104.

Lillard scored 16 points in the first quarter to give the Trail Blazers a 31-18 lead, and they had little trouble keeping a comfortable margin against a banged-up and slumping team for most of the night.

"He came out and set the tone for us," coach Chauncey Billups said. "He usually does."

In other matches, Miami edged Atlanta 130-128, Denver downed Toronto 118-113 and Sacramento beat New Orleans 123-108.
