Miami’s Bam Adebayo has produced one of NBA’s all-time most remarkable performances, pouring in 83 points for the second-highest tally in a game in league history.

Adebayo went 20-43 from the field and a whopping 36-43 from the free-throw line in Miami’s rout of Washington, with his points total behind only the legendary Wilt Chamberlain’s 100-point game from 1962.

The Heat centre passed Kobe Bryant’s total of 81 from 2006 - which had been the previous No.2 ranked scoring performance - with a string of late free throws.

Miami torched a Wizards outfit featuring former Perth Wildcats centre Alex Sarr 150-129.

“I wish I could re-live it twice,” Adebayo said after the game.

“I thank God, my family and my teammates... they kept feeding me the ball.”

Adebayo, a two-time Olympic gold medal winner, had a previous career-high points tally of 41 before more than doubling that on Tuesday night (US time).

He had 31 in the first quarter to help set up his history-making effort.

Adebayo’s night also broke new NBA records for most free throws attempted and made, while his whopping 22 three-point attempts - making seven of them - marked the third-most in league history.
