Obi Toppin scored 20 points, Andrew Nembhard added 17 and the Pacers forced a winner-take-all Game 7 by rolling past the Oklahoma City Thunder 108-91 on Thursday night.

The first Game 7 in the NBA Finals since 2016 is Sunday night in Oklahoma City.

“The ultimate game,” Pacers coach Rick Carlisle said.

Pascal Siakam had 16 points and 13 rebounds for Indiana, while Tyrese Haliburton — playing through a strained calf — scored 14 points. The Pacers started slowly and then turned things into a blowout.

Game 6 was a microcosm of Indiana’s season in a way. The Pacers started the regular season with 15 losses in 25 games, have had five comebacks from 15 or more down to win games in these playoffs, and they’re one win from a title.

“We just wanted to protect home court,” Haliburton said. “We didn’t want to see these guys celebrate a championship on our home floor. Backs against the wall and we just responded. ... Total team effort.”

TJ McConnell, the spark off the bench again, finished with 12 points, nine rebounds and six assists for Indiana.

Shai Gilgeous-Alexander scored 21 points for the Thunder, who pulled their starters after getting down by 30 going into the fourth. Jalen Williams added 16.
