Boston will host Game 2 on Thursday night.The Pacers defeated the Celtics, who were still without seven-foot center Kristaps Porzingis, by making thirteen 3-pointers and scoring fifty-six points in the paint behind Tyrese Haliburton’s twenty-five points and ten assists.

12 rebounds and 24 points were added by Pascal Siakam. The sixth-seeded Pacers, led by Myles Turner, who finished with 23 points and 10 rebounds, twice turned the ball over while holding a three-point advantage in the last 30 seconds of regulation.

With Siakam squarely in his face, Brown made them pay for the second one by tying the score at 117 with a three-pointer from the corner.

With 1:46 left, Haliburton made all three of his free throws after being fouled, giving Indiana the lead again, 123–121. Tatum then used his strength to make a layup, but T.J. McConnell fouled him. With his final three-pointer, he gave Boston a decisive lead.

The Pacers passed it over to Haliburton once more. Tatum was the recipient of the ball at the top of the key. With 43 seconds remaining, he pumped, sidestepped a defender, and sank a three-pointer to make it 127-123.

Siakam and Derrick White exchanged layups. After being fouled, Holiday made two free throws to give Boston a 131-125 lead.
