INDIANAPOLIS – The Indiana Pacers came in as the returning Eastern Conference finalist most had forgotten about. All of New York, and the basketball world, remembers them now.

The Pacers won Game 6 over the Knicks, 125-108, on Saturday to clinch their second NBA Finals berth and a matchup against the league’s best regular-season team, with MVP Shai Gilgeous-Alexander on its side, the Oklahoma City Thunder.

Game 1 in Oklahoma City is at 8:30 p.m. Eastern on Thursday. Indiana has never won an NBA title. The Thunder have one – from 1979 when they were the Seattle SuperSonics.

“I can’t put into words how special this is,” said Tyrese Haliburton, the face of the Pacers. “We got to the same spot last year, fell short, and we just worked our tails off to get back here.”

Pascal Siakam, voted the MVP of the conference finals, led Indiana with 31 points to go with five boards, while Haliburton turned in a brilliant double-double with 21 points and 13 assists – 11 of those points in the fourth quarter.

Siakam won MVP and collected the Larry Bird trophy by a narrow vote of nine media members covering the series, beating out Haliburton by one vote. Siakam averaged 24.8 points and shot better than 50 percent or better from both the field and 3-point range. Haliburton averaged 21 points and 10.5 assists, but didn’t get going until late in Game 6 after a brutal performance in a Game 5 loss, which probably cost him that single vote.

“Enjoy tonight and after that look forward,” said Siakam, who won a title with the Toronto Raptors in 2019. “We have a team out there waiting for us that’s serious. They’re the best team in the NBA.”

Andrew Nembhard, who had struggled to shoot for much of the series, contributed 14 points, eight assists and six steals. He knocked down a 3 with 4:20 left to put the Pacers up by 19.

The Knicks were led by OG Anunoby with 24 points. Jalen Brunson, who arguably had the best series of any player on the court, contributed 19 points but shot 8-of-18 and was hounded defensively by Nembhard. Karl-Anthony Towns, playing on a sore knee, finished with 22 points and 14 rebounds. The Knicks got to the conference finals by pulling a significant upset in besting the defending-champion Boston Celtics in six games.

“There’s disappointment because you fall short of what your goal is – only one team achieves the goal,” Knicks coach Tom Thibodeau said.

This is the Pacers’ first trip to the finals since 2000 when they beat, coincidentally, the Knicks in six games. Indiana made it to the conference finals last year by beating the Knicks in a Game 7, only to be swept by the Celtics. Indiana was a No. 6 seed a year ago and entered this spring’s tournament as a four seed, behind the Cleveland Cavaliers, Boston and the Knicks.

After a gentleman’s sweep of the Bucks, who lost Damian Lillard to a torn Achilles, the Pacers stunned – and largely dominated – a Cavs team that fought with Oklahoma City all season for the league’s best record.

Following a similar playbook to their first two series triumphs, the Pacers used their style of relentless pressure and relied on their depth to wear down the Knicks over six games.

“This was as intense of a series as you’re ever going to have in six games,” Indiana coach Rick Carlisle said.

The series had it all, from Haliburton’s lucky bounce that tied Game 1 at the buzzer, followed by his Reggie Miller choke sign, to a 20-point comeback by the Knicks in Game 3, to ESPN personality Pat McAfee calling New York’s traveling celebrity fan base of movie stars Timothée Chalamet, Ben Stiller, and Spike Lee “sons of (expletive)” into the Gainbridge Fieldhouse in Game 4. Kylie Jenner made the trip to Indianapolis for Game 6 with her boyfriend, Chalamet, who has emerged as Lee’s deputy general among famous Knicks faithful. Jon Hamm knocked a ball away from Haliburton as it was headed out of bounds during a game in New York; Haliburton’s father was allowed back at games midway through the series after a temporary ban for taunting Giannis Antetokounmpo.
