Mike Scott made five 3-pointers during a 30-6 second-quarter run Monday night in Indianapolis, and the Atlanta Hawks fended off a furious fourth-quarter rally to beat the top-seeded Pacers, 107-97, and take a 3-2 lead in the best-of-seven series.
Atlanta can clinch the first-round series at home Thursday.
Scott scored all 17 of his points during an incredible 12-minute stretch when Atlanta went 13 of 16 from the field and outscored Indiana, 41-19, to take a 61-40 halftime lead. The Hawks and the 1970 Milwaukee Bucks are the only road teams in the shot-clock era to score at least 40 points and allow fewer than 20 in any quarter of a playoff game.
‘‘We can play with this team,’’ Scott said. ‘‘They’re a great team, especially at home, great players, great coach, but we have a belief in ourselves as well.’’
Shelvin Mack led the eighth-seeded Hawks with 20 points.
Paul George had 26 points for Indiana, which got as close as 8 in the final minute.
For the Pacers, it was another bleak chapter in a second-half implosion that could go down as the worst in NBA history if they can’t survive this series. On Monday, one of the league’s best defensive teams inexplicably collapsed in the second quarter. Atlanta was 9 of 11 from beyond the arc in the quarter and shot 81.3 percent from the field during a second quarter in which the Pacers allowed their most points ever in a playoff game, and the Hawks matched their second-highest scoring total in the same quarter during a postseason game.
Atlanta previously did it against Detroit on April 17, 1986. The St. Louis Hawks scored 45 points against Fort Wayne on March 14, 1957.
‘‘It was frustrating because we didn’t make a change,’’ George said of the Pacers’ defense. ‘‘We let them run the same action, the same shot. We didn’t do nothing. So that was frustrating.’’
Indiana never fully recovered. The Pacers trailed by 21 at halftime and by as many as 30 in the third quarter.
Heat 109, Bobcats 98 — LeBron James scored 31 points as Miami completed a first-round sweep in Charlotte, N.C.
James scored 19 points after injuring his thigh in the third quarter. He finished 10 of 19 from the field and had nine assists. Chris Bosh added 17 points and Dwyane Wade battled through foul trouble and finished with 15 as Miami won its 20th straight game over Charlotte. The Heat will await the winner of the Brooklyn-Toronto series, which is tied, 2-2.
Kemba Walker led Charlotte with 29 points. The Bobcats played without Al Jefferson, their leading scorer and rebounder, who suffered a foot injury early in Game 1.
Spurs 93, Mavericks 89 — Manu Ginobili scored 23 points, Boris Diaw hit a go-ahead 3-pointer in the final minute, and San Antonio held off a second-half surge by host Dallas, pulling even in their first-round playoff series.
The Spurs regained the home-court advantage by getting a split of two games in Dallas, matching what the eighth-seeded Mavericks did in San Antonio.
The Spurs led by 20 points in the third quarter before the Mavericks pulled even midway through the fourth quarter. The score was still tied when Diaw hit from long range over Dirk Nowitzki at the top of the key for a 90-87 lead.
Monta Ellis led Dallas with 20 points, but missed two potential tying shots after Diaw’s basket.
