The Hornets avoided a larger first-half deficit as they converted 21-of-28 free throws.

Nicolas Batum scored 24 points and Kemba Walker finished with 19 points for Charlotte.

Unlike the Heat’s regular-season finale at Boston on Wednesday, when they squandered a 24-point halftime lead and lost by double digits, Miami built a 17-point advantage at halftime and ran off seven unanswered points to start the second half.

Deng scored five points during the early second-half spurt and his layup 2:23 into the second half gave Miami a 74-50 lead.

Game 2 will be Wednesday night at Miami before the series shifts to Charlotte for games three and four Saturday and April 25.

NOTES: F Nicolas Batum tested his sore left ankle in workouts before Game 1 to gauge his eventual availability for the series opener. Batum, who averaged 14.9 points per-game, sat out Charlotte’s regular season finale against Orlando on Wednesday. … C Al Jefferson continued his reserve role in game one. Coach Steve Clifford considered returning Jefferson to the starting lineup but opted to remain with Cody Zeller at center. … C Hassan Whiteside, F Justise Winslow and G Josh Richardson made their playoff debuts against Charlotte. Meanwhile, Heat veterans G Dwyane Wade, F Joe Johnson and F Udonis Haslem have a combined 377 post-season appearances entering Sunday’s game. … A sore left foot won’t keep Haslem from playing in the series, according to coach Erik Spoelstra said. “I’ve seen the man play through, literally, a broken foot for two months in the playoffs,” Spoelstra said.
