Indiana’s Tyrese Haliburton sank the game-winning basket with 0.3 of a second remaining to give the Pacers a stunning 111-110 fightback victory over Oklahoma City in Thursday’s opening game of the National Basketball Association (NBA) Finals.

Haliburton, who had 14 points and 10 rebounds, gave the Pacers their only lead of the game on a dramatic 21-foot jump shot to deliver a shocker after Indiana had trailed by 15 points with 9:42 remaining.

“I’m confident in my ability and feel like if I can get to my spot I’m really comfortable from there. I really had confidence in my shot,” Haliburton said of the game winner.

“We’re just a really resilient group. We did a great job of just walking them down. When it gets to 15, you can panic or you can talk about how you get it to 10, to five and from there. We just stuck with it.”

“We got a big stop there and they had a lot of confidence in me to make that shot.”

With a game-closing 14-2 run, the Pacers seized a 1-0 lead in the best-of-seven series with Game 2 on Sunday in Oklahoma City.

“We’ve got to learn from it. There are obviously a lot of things we can clean up. Credit them. They went and got that game,” Thunder coach Mark Daigneault said.

“They’ve had so many games like that that have seemed improbable and they just play with a great spirit and keep coming.”

It was the fifth 15-point-or-greater winning comeback by Indiana in this year’s playoffs, the most by any team since 1998.

“They went up 15 and we just said let’s just keep chipping away at the rock,” Pacers coach Rick Carlisle said. “We had a lot of experience in these kind of games and our guys have a real good feel for what it’s all about, giving ourselves a chance.”

“We got fortunate, but made plays.”

Pascal Siakam led the Pacers with 19 points while reserve Obi Toppin added 17, Myles Turner had 15 and Haliburton and Andrew Nembhard each added 14.

“It was a total team effort,” Haliburton said.

“We had so many guys chip in.”

The finish evoked memories of the first game in the Eastern Conference finals, when a Haliburton buzzer shot forced over-time as the Pacers stunned New York. He has four such deciders in the playoffs.

The Pacers seek the first NBA crown in their 58-year history while the Thunder, a champion in 1979 as Seattle, have not won a crown since moving to Oklahoma City in 2008.

“We know we have a lot of work to do,” Indiana’s Carlisle said.

“We have to play a lot better... and they are a menace defensively.”

Indiana overcame 24 turnovers, allowing the Thunder only 11 points off them, and a 38-point performance by NBA Most Valuable Player Shai Gilgeous-Alexander.

“It’s not rocket science. We have to be better,” Gilgeous-Alexander said.

A 12-2 run pulled Indiana within 98-94 with 6:16 remaining in the fourth quarter, with Turner and Toppin each making two three-pointers.

The Thunder, with the NBA’s best regular-season record, clung to the lead but could not hold on.
