Trae Young remains as poised as ever in hostile environments in his first postseason.

Young scored 48 points, Clint Capela converted a go-ahead putback with 29.8 seconds left and the Atlanta Hawks beat the Milwaukee Bucks 116-113 on Wednesday night to open the Eastern Conference finals.

Game 2 is Friday night in Milwaukee.

Giannis Antetokounmpo had 34 points, 12 rebounds and nine assists for the Bucks. Jrue Holiday added 33 points and 10 assists.

Milwaukee’s Khris Middleton missed a potential tying 3-pointer in the closing seconds. Although Middleton scored 15 points, he shot 6 of 23 and missed all nine of his 3-point attempts.

“I’ve just got to be better,” Middleton said. “It’s as simple as that.”

Never before had the Hawks won an Eastern Conference finals game since moving to Atlanta in 1968. The Hawks reached the East finals in 2015, but were swept by Cleveland.

The Hawks did win a title in 1958 and reached the league finals in 1957, 1960 and 1961 when they were in St. Louis.
