Rookie Andrew Nembhard hit a 3-pointer at the buzzer, and the Indiana Pacers rallied from a 17-point deficit in the fourth quarter for a stunning 116-115 victory over the Los Angeles Lakers on Monday night.

Tyrese Haliburton scored 24 points and hit a tying layup with 39 seconds left for the Pacers, who trailed 101-84 early in the fourth. LeBron James hit a one-handed floater with 20.9 seconds left, and Myles Turner missed an ensuing 3-point attempt for Indiana — but Haliburton got the long rebound and eventually found Nembhard alone on the perimeter with a crosscourt pass.

The Canadian second-round pick from Gonzaga drilled his fourth 3-pointer of the night over the onrushing James’ outstretched hand. The bucket crushed the LA crowd and set off a frenzied on-court group celebration that even included Pacers president of basketball operations Kevin Pritchard.

“I think you stay calm (because) you work in the gym for those types of moments,” Nembhard said. “You’ve just got to bring your confidence, and when it comes, you’ve just got to step up for the team in that way. I think it was a great team win. We had a lot of contributions from a lot of guys, and it was just my turn to step up in that moment.
