PHILADELPHIA — Josh Hart raised his arms and extended three fingers on each hand following his go-ahead 3-pointer from the top of the arc with 24.4 seconds left on the clock, which was just enough to send the New York Knicks past the Philadelphia 76ers and into the second round of the playoffs on Thursday night.

The Knicks finished Game 6 with a slender 118-115 scoreline.

Jalen Brunson had 41 points and 12 assists to lead the Knicks, which are set for an Eastern Conference semifinal matchup with Indiana.

The Pacers beat Milwaukee in six games and advanced to the second round for the first time in 10 years.

Jalen Brunson became the first Knick to do that since Bernard King 40 years ago, and the first NBA player to score 40 or more to close out a series since Michael Jordan for Chicago against Cleveland in 1989

Game 1 is on Monday in New York.

The Knicks are through to the second round in consecutive years for the first time since the postseasons between 1992 and 2000, and even then, nobody did what Brunson did in this series by scoring 40 points or more in each of the final three games.

He became the first Knick to do that since Bernard King 40 years ago, and the first NBA player to score 40 or more to close out a series since Michael Jordan for Chicago against Cleveland in 1989.

In a series defined by tight games, Hart hit the clutch shot that made it 114-111, and again had “Let’s go Knicks! Let’s go Knicks!” chants echoing around Philly’s home court. Joel Embiid scored a bucket, but fouled out on the next possession. Donte DiVincenzo sealed New York’s win with two free throws.

“The fourth quarter was just one big play after the next,” Knicks coach Tom Thibodeau said.

Naturally, the former Villanova Wildcats trio of Hart, DiVincenzo and Brunson saved the Knicks from a first-half collapse that was nearly enough to force a Game 7. DiVincenzo scored 23 points and Hart had 16.

Embiid finished with 39 points and 13 rebounds. Buddy Hield had 20 points. After dropping 45 points in Game 5, Tyrese Maxey was a non-factor in the first half and finished with 17.

“This series probably could have gone the exact opposite the way it did,” 76ers coach Nick Nurse said. “But it didn’t.”

Despite Philadelphia’s best efforts to keep rowdy Knicks fans at home, Wells Fargo Center sounded more like Madison Square Garden in the waning moments. Knicks fans crowded near New York’s tunnel after the game and held their phones high to capture video of their playoff heroes as they headed to the locker room

The 76ers still haven’t made it past the second round since 2001, and can pin the bulk of the blame in this one on their starters. Tobias Harris, in the final year of a five-year, $180 million contract, went scoreless. So did Kyle Lowry.

Despite Philadelphia’s best efforts to keep rowdy Knicks fans at home, Wells Fargo Center sounded more like Madison Square Garden in the waning moments. Knicks fans crowded near New York’s tunnel after the game and held their phones high to capture video of their playoff heroes as they headed to the locker room.

“Was it hostile?” Thibodeau replied sarcastically, when asked about the atmosphere.

This was a game where it seemed natural to want to skip ahead to the final minute. After all, there have been five playoff games since the 1996-97 season where a team trailed by five or more in the final 30 seconds of regulation and came back to win — and two were in this series.

In Game 2, the Knicks rallied to win 104-101.

Game 5, the 76ers came back for an 112-106 overtime win.

Exhilarating and exhausting, there were more can-you-top-this moments to come.

With Sixers fans having seized back the building, they were roaring at the late tip-off, only for the Knicks to come roaring out to a 33-11 lead.

Just last season, the 76ers held a 3-2 series lead against Boston in the East semifinals, only to drop Game 6 at home, and then Game 7 in Boston.

The Sixers lost Game 6 and the East semis in 2022 at home to Miami.

Only, in this Game 6, the Sixers showed some moxie.

With Maxey unable to find a shot, Hield almost saved the season. Acquired at the trade deadline, Hield lost his starting spot after a late-season slump. He missed all four 3-point attempts in the first three games of the series and did not play in the last two. Hield found his shot in Game 6, hitting five 3s in the second quarter that sparked a 34-11 run for the Sixers.

His fifth 3-pointer helped send the Sixers into the half with a 54-51 lead.

Maxey hit a 3 for a 10-point lead in the third, before a pair of wild misses from beyond the arc sparked a Knicks rally. OG Anunoby closed the third quarter with a tying 3 for New York, and he opened the fourth with another for an 86-83 lead. With the game tied at 95-all,

Brunson hit a step-back 3 and then another 3 that made it 101-95.

Anunoby’s dunk for an eightpoint Knicks lead with 2:43 left looked like it might be decisive, but the Sixers had one more run in them.

“A lot of our guys don’t have playoff experience,” Thibodeau said. “I think going through a series like this will be invaluable for them.”
