The win is the Hawks' first of the series, keeping things alive at 2-1 with Game 4 remaining in Atlanta, while Kyle Lowry may be missing for the Heat after leaving Friday's game with a hamstring complaint.
Momentum switched hands throughout the contest, with Atlanta putting up 39 points in the second quarter to lead 61-54 at half-time, before the Heat came out on fire in the third, winning the frame 31-16 to take an eight-point lead into the last.
Miami extended their lead to 94-80 with 9:06 to play in the fourth quarter, when Bogdan Bogdanovic and Onyeka Okongwu began to drag the home side back into the game.
Bogdanovic hit a trio of three-pointers in less than three minutes, while Okongwu had seven points down the stretch and was the Hawks' primary defensive presence on the interior, more than holding his own against Bam Adebayo and Jimmy Butler.
But after a P.J. Tucker three-ball put the Heat up 110-109 with 54 seconds to play, only one man was going to have the final say for the Hawks.
When Butler missed a jump shot with 12 seconds left, the Hawks opted not to call a time-out, letting Young make his way up the court quickly, weaving his way into the lane for one of his trusty floaters, getting the friendly home-rim roll.
He finished with 24 points on six-of-14 shooting, also dishing nine assists. Bogdanovic had 18 points, eight rebounds and six assists, and De'Andre Hunter scored 17, including some important buckets when the Hawks were sputtering.
Butler's desperation three on the buzzer fell short, but he played well, scoring 20 (eight-of-20 shooting) with 10 rebounds and eight assists, while Tyler Herro led the Heat in scoring with 24 off the bench and Max Strus had 20, hitting five-of-10 from three-point range.
Paul, Ayton carry Phoenix
The duo of Chris Paul and Deandre Ayton led the top-seeded Phoenix Suns to a crucial Game 3 114-111 win against the New Orleans Pelicans to take a 2-1 lead in the series.
With Devin Booker absent for at least this game and the next, Paul had to take on a greater offensive burden than usual, but he did it in style, racking up 14 assists and scoring 28 points on 10-of-18 shooting.
He needed someone to get hot with him, and Ayton rose to the occasion, scoring 28 points on 13-of-20 shooting and grabbing 17 rebounds, with three steals and a block. The performance demonstrated the ability to be an offensive focal point that was envisioned when he was selected number one overall in the 2018 NBA Draft.
It was far from smooth sailing for the Suns, as the Pelicans kept it close throughout, and even poked their head in front at 93-92 with less than six minutes to play.
But the Suns as has been the story of the Suns' season, they have been the best clutch team in the NBA, and once again showed why. Paul's surgical precision on the offensive end, and a sea of swarming length and physicality on the defensive end, was too much for a young Pelicans team that played three rookies in the fourth quarter (Herb Jones, Trey Murphy III and Jose Alvarado).
Brandon Ingram had 34 points on 11-of-19 shooting in a strong performance for New Orleans, and C.J. McCollum also contributed 30 points (11-of-23 shooting), but no other Pelican could score more than a dozen.
Bucks cruise without Middleton
The Milwaukee Bucks were shot out of a cannon and never allowed the Chicago Bulls a foothold into the game, winning 111-81 to take a 2-1 series lead.
With extended minutes due to Khris Middleton's knee injury, Grayson Allen set the tone to close the first quarter, scoring three consecutive three-pointers in just 62 seconds on his way to a game-high tally of 22 points.
With 1:15 to play in the first half, the Bucks opened up their lead to 60-37 as they dominated both ends of the floor.
Giannis Antetokounmpo only needed to play 29 minutes before getting an early rest, scoring 18 points (seven-of-12 shooting) with seven rebounds and nine assists, and the Bucks were plus 36 during his time on the floor.
After only playing six minutes in the Game 2 loss, Bobby Portis made his case for his playoff value with 18 points and 16 rebounds, hitting four of his eight three-point attempts.
