NEW YORK — Jalen Brunson scored 30 points and keyed the run the New York Knicks needed just in time to get by a Miami Heat team playing without Jimmy Butler, evening the Eastern Conference semifinals at a game apiece with a 111-105 victory Tuesday night.

Julius Randle returned from a sprained left ankle that sidelined him in Game 1 with 25 points, 12 rebounds and eight assists, and RJ Barrett scored 24 points for the No. 5-seeded Knicks. Josh Hart finished with 14 points, 11 rebounds and nine assists.

But it was Brunson, who pointed the blame at himself and said he had to be better after going 0 for 7 from 3-point range in the opener, who made the biggest plays in a game the Knicks trailed much of the way.

Caleb Martin scored 22 points in place of Butler for the Heat, who host Game 3 on Saturday afternoon. They will hope to have Butler, the leading scorer in the playoffs who sat out after spraining his right ankle late in their 108-101 victory in the opener.

They almost didn’t need him.

Miami had a six-point lead midway through the fourth quarter thanks to undrafted players Martin and Gabe Vincent before Brunson, who had been listed as questionable with a sore right ankle, took over.

He made a 3-pointer that became a four-point play when Isaiah Hartenstein was fouled on the play, and the point guard then scored to knot it at 93.

The Heat went back up 96-93 on Vincent’s three free throws, but Josh Hart tied it with a 3 before Brunson hit a 3 and scored again to make it 101-96 with 2:48 remaining.

Brunson went 6 of 10 behind the arc.

Randle was originally hurt against Heat in a victory March 29 after starting the first 77 games. He returned for the start of the playoffs but wasn’t sharp for much of the series against Cleveland before reinjuring the ankle in the Game 5 clincher.

He was much better Tuesday for a Knicks team trying to advance to the Eastern Conference finals for the first time since 2000, when they got there after beating Miami in seven games.

Randle had assists on two of the Knicks’ first three baskets, with the Heat paying extra attention to him and leaving shooters open on the perimeter. But the No. 8-seeded Heat stayed right with them by making six 3-pointers and the Knicks led just 31-29 after one.

Like in the opener, the Heat dug in defensively from there. They limited the Knicks to just two baskets in the first 8 1/2 minutes of the second, building their lead to 46-38, and were ahead 54-51 at the break after Kevin Love’s 3-pointer with 6.1 seconds remaining.

The Knicks finally went back into the lead when Brunson hit a couple 3s and then another basket, but Vincent’s basket sent Miami to the fourth with a 77-76 edge.

Heat: Vincent scored 21 points. ... Max Strus finished with 17 points but missed part of the second half after going to the locker room with a bruised lower back.

Knicks: Starting center Mitchell Robinson committed two fouls in the first 2:31 and sat the remainder of the first quarter. ... The crowd included comedians Chris Rock and Mike Myers, retired tennis star Roger Federer, former Knicks All-Star Carmelo Anthony and actress Jessica Alba.
