Miami's two stars have never looked better together.

Adebayo scored 37 points with 14 rebounds and Antetokounmpo also scored 37 as the Heat beat the Cleveland Cavaliers 133-121 in an NBA Cup game Friday night in Miami.

They are the first Heat duo to each score at least 35 in the same game since LeBron James and Dwyane Wade.

Bam takes over

Adebayo made 13 of 19 shots and 9 of 10 free throws. He did not commit a turnover.

His biggest stretch came with Antetokounmpo on the bench. Adebayo scored 14 points in the first seven minutes of the fourth quarter as Miami turned a 92-91 lead into a 115-103 cushion.

"Those minutes with Giannis on the bench were very inspiring," Heat coach Erik Spoelstra said.

Antetokounmpo was nearly perfect early. He made 14 of his first 17 shots and finished 15 of 20 with nine rebounds.

Mitchell runs the show

Davion Mitchell had 22 points and 17 assists with one turnover. The assists tied his career high and fell two short of Tim Hardaway's franchise record from 1996.

Rookie Ryan Conwell scored 20 off the bench.

Miami did it without starters Klay Thompson (ankle) and Pelle Larsson (illness).

Cleveland comes up short

Donovan Mitchell scored 25 points for the Cavaliers. Tyrese Proctor added 22 and James Harden had 20.

Cleveland played without Evan Mobley, who missed his first game of the season with a sprained left big toe.

What's next

The Heat have won three straight to reach 6-6. They are 2-0 in NBA Cup play and alone atop East Group B.

Cleveland fell to 6-7. Miami hosts Detroit at 7 p.m. Central on Saturday. The Cavaliers host Dallas the same night.
