Trae Young scored 32 points, including a last-second, go-ahead floater, to give the Atlanta Hawks a 129-127 win over the Sixers, ending their six-game winning streak.

With 3.5 seconds remaining, Young took the inbound pass from Kevin Huerter and dribbled past Jimmy Butler before lifting the short, soft jumper from near the free-throw line. The shot dropped through the net with 0.1 seconds remaining.

Young’s game-winner left 76ers center Joel Embiid stunned. After most of his teammates had showered and dressed, Embiid still sat at his locker in his uniform, staring at the final stats.

Atlanta has won two of three from the 76ers, including a split of two games in Philly.

Butler said the 76ers still came in too confident, thanks to the winning streak.

“I think it’s the fact that we think that we’re a good team so we can just come in and do whatever we’re going to do and think that we’re still gonna win,” Butler said. “… I’m telling you, I think that’s what it was.”

The 76ers still have a solid hold on third place in the Eastern Conference, three games ahead of Indiana and four games ahead of Boston. Their six-game winning streak included a win over Boston on Wednesday night.

Butler missed a long attempt after the final buzzer sounded.

Taurean Prince had 23 points for Atlanta.

Embiid had 27 points and 12 rebounds, and Butler had 25 points.

After snapping Utah’s five-game winning streak by beating the Jazz 117-114 on Thursday night, the Hawks dropped another streaking playoff-bound team.

Young’s long 3-pointer with 1:15 remaining gave Atlanta a 125-123 lead.

“Those two buckets effectively won the game,” said 76ers coach Brett Brown, who said Young “was unique tonight.”

Butler, who tied the game with a layup, sank two free throws to give Philly a 127-125 lead. Prince answered with a tying layup.

The Hawks were left with 3.5 seconds after the 76ers’ 24-second violation, with Butler’s miss waved off as coming too late.

Atlanta’s John Collins had a short description of the decisive play. “Give the ball to Trae, and he takes off,” Collins said.

Atlanta led 74-68 at halftime and stretched the lead to 12 points, at 97-85, on Alex Len’s three-point play. The 76ers closed the gap with 10 straight points and pulled even at 100-all on JJ Redick’s 3-pointer to end the third period.
