It was 34-33 Indiana with about four minutes gone in the second quarter. And about four minutes into the third quarter, it was 70-42 Indiana — the game having completely gotten away from the Thunder.

The run was 36-9 — repeat, 36-9 — and just like that, a team that won 68 games in the regular season and finished with the best record in the NBA has been pushed to the brink by an Indiana team that finished 18 games back of the Thunder in the league standings.

They’re even now: The series is 3-3, and it all comes down to Sunday.

“We have to be better at course correcting, getting ourselves back on the right track,” Thunder forward Chet Holmgren said. “I, personally, could be better in trying to help us get things going in the right way.”

During that 36-9 run, the Thunder were offensively inept: They shot 3 for 18 during those minutes, with seven turnovers in there to make matters even worse.

The rest of the numbers were bad as well:

Oklahoma City had 21 turnovers to Indiana’s 11.

The Thunder were outscored 45-24 from 3-point range.

Indiana turned 11 offensive rebounds into 14 points, while Oklahoma City had only four offensive rebounds for six points.

The Pacers had 22 fast-break points to Oklahoma City’s 11.
