Pascal Siakam scored 21 points, Myles Turner and Obi Toppin each scored 20 and the Pacers tied an NBA playoff record with a 41-point halftime lead before blowing out the Cavs 129-109 to take a 3-1 series lead.

The No. 4-seeded Pacers can close it out Tuesday in Cleveland, where they’ve already won twice.

“We haven’t done anything yet,” coach Rick Carlisle said after earning his 33rd playoff win with Indiana, passing Larry Bird for the most in the franchise’s NBA history. “We’re going to keep approaching this like we have everything to prove. We know people don’t believe in us, so we’re just going to stay in the fight and keep fighting.”

The Pacers certainly showed some resolve two days after an embarrassing 22-point loss on their home court, a game in which Cleveland dominated the glass and held two-time All-Star Tyrese Haliburton to four points and five assists.

The Pacers built a 44-point lead before settling for an 80-39 halftime margin that matched the league’s previous best since detailed play-by-play was kept, set by the Cavs in Game 2 of the 2017 Eastern Conference finals against Boston.

Turner made all four of his 3-point attempts with Indianapolis 500 winners Dario Franchitti and Scott Dixon, WNBA Rookies of the Year Caitlin Clark and Aliyah Boston, and former NFL star Reggie Wayne in the crowd.
