Malik Beasley made a technical free throw with 1.1 seconds left in overtime and the host Detroit Pistons escaped with a wild 123-121 victory over the Miami Heat in the NBA Cup opener for both teams on Tuesday night.

Tyler Herro, who scored the final nine regular-season points, all on three-pointers, to force overtime, gave the Heat a two-point lead on a bank shot with 1.8 seconds left in overtime. An alley-oop dunk by Jalen Duren off an inbound Cade Cunningham pass tied the score.

The Heat called a timeout they didn’t have, resulting in the 122-121 technical lead. Beasley then split two free throws after Miami was called for a taking foul.

Beasley and Cunningham finished with 21 points each. Cunningham also had nine assists and seven rebounds, but was responsible for seven of the Pistons’ 19 turnovers. Jaden Ivey had 19 points, Tobias Harris added 18 and Isaiah Stewart finished with 13 points and 10 rebounds.

Herro scored 40 points. His 10 three-pointers tied a Heat record and are an NBA Cup single-game record. Bam Adebayo added 20 points and 12 rebounds.

The Heat played their second straight game without Jimmy Butler, who has a sprained right ankle.

Detroit scored the first 10 points of the game and led 32-21 by the end of the quarter.

The lead grew to 18 when the Pistons scored the first seven points of the second quarter. The pillow did not last long.

The Heat responded with a 23-4 run for a one-point lead. Detroit ended the half on a 10–4 run to take a 57–51 lead at halftime.

Cunningham’s first basket of the game, a 3-pointer, gave Detroit a 64-59 lead early in the second half. The Pistons ended the third on an 8-2 run and led 91-82.

Herro hit consecutive three-pointers to cut the Pistons’ lead to eight midway through the quarter.

When Stewart dunked with two minutes left, Detroit’s lead was still nine.

After an offensive mistake by Ivey, Herro erupted with his late onslaught of three-pointers on consecutive possessions, tying the score at 111-all. After a Pistons turnover, Herro missed a shot up the middle on Miami’s final possession.
