Jimmy Butler set a personal playoff high with 47 points to lead Miami to a 111-103 victory over hosts Boston and tie the Eastern Conference finals at three games apiece on Friday.
Jimmy also had nine rebounds, eight assists and four steals to force the series to a decisive seventh game at the Heat’s home on Sunday.
Ten years after LeBron James scored 45 points in Boston to help the Heat avoid elimination in Game 6 of the conference finals en route to the first of their back-to-back NBA titles, Butler had 17 points in the fourth quarter to top him.
A win in front of their home fans will take the Heat to the NBA Finals for the second time in three years.
In the most back-and-forth game of the series, Boston took a 97-94 lead on Derrick White’s 3-pointer with under five minutes to play – the first time all series the lead has changed hands in the fourth quarter.
Kyle Lowry answered with a three and then added two free throws as Miami scored 11 of the next 13 points.
Lowry finished with 18 points and 10 assists before fouling out with 2:18 left. Butler made 16 of 29 shots, hitting 4 of 8 from 3-point range and all 11 free throws.
Jayson Tatum had 30 points and nine rebounds and Derrick White came off the bench to score 11 of his 22 points in the fourth quarter for Boston.
The Celtics are trying to reach the finals for the first time since 2010.
Boston’s Jaylen Brown scored 20 points, missing a pair of free throws with the game tied at 99 after Lowry fouled out.
Brown fouled out himself on a charge offensive that was assessed after a challenge on a missed dunk with 13 seconds left and the Celtics down by four.
