Tatum, Brown combine for 62 points as Celtics defeat Hawks, advance to face 76ers

After letting the series go longer than it should have, Al Horford and the visiting Boston Celtics were eager to finish off the Atlanta Hawks.

Horford made sure his former team didn’t force a Game 7.

The 36-year-old Horford hit a huge three-pointer in a late run that carried the Celtics past the Hawks 128-120 Thursday night for a 4-2 triumph in the opening-round playoff series.

After squandering a 13-point lead in the fourth quarter of Game 5, which cost them a chance to end the series in Boston, the Celtics were determined not to wilt again.

Down by three, Boston ripped off an 11-0 run that included three straight three-pointers, with Horford’s big shot sandwiched around threes from Jayson Tatum and Jaylen Brown.

Tatum capped the spurt with a dunk off a Horford miss, giving the Celtics a 121-113 lead with 2:07 remaining.

Given how close it had been all night, an eight-point lead seemed like 80 in a game that featured 22 lead changes and 15 ties.

Now, bring on Philly.

The second-seeded Celtics advanced to face the third-seeded Philadelphia 76ers, who’ve been resting since completing their four-game sweep of Brooklyn last Saturday.

Game 1 is Monday night in Boston.

Brown led the Celtics with 32 points, while Tatum had 30. Horford, who played in Atlanta from 2007-16, chipped in with 10 points, 12 rebounds two steals and three blocks.

“It was huge,” Brown said. “Al came through for us.”

After knocking down a three from the corner, which put the Celtics ahead to stay, Horford yapped back at an Atlanta fan who had been trash talking him from the sideline.

“I appreciated it because he got me going. He said some stuff that I wasn’t very pleased with. I took it to heart and I was able to get that shot,” Horford said. “I appreciate him for talking trash to me. Some people you can talk trash to. Talk trash to me — it’s probably not good for you.”

Marcus Smart also came up big for Boston, scoring 22 points and brilliantly running the offence down the stretch, including a drive and dish that set up Horford’s shot.

Young runs out of steam

After carrying the Hawks to that improbable victory at TD Garden, Trae Young ran out of steam in the second half. He missed 12 of 13 shots over the final two quarters.

Young had 30 points and 10 assists, but he finished just nine of 28 from the field.

Despite a largely disappointing season that included a coaching change and another first-round exit from the playoffs, Young is optimistic about the Hawks’ future.

He’s especially looking forward to a full season under Quin Snyder, who took over from Nate McMillan with 21 games left in the regular season.

“Quin is the future,” Young said. “I believe with him here, this city’s going to win a championship.”

Murray seemed a bit out of sync, missing all five of his shots in the first half. He was better in the second half but still managed just 14 points.

The Hawks needed a few more to keep their season going.

“We were right there,” Snyder said.

Young forced the series back to Atlanta with a long three-pointer that stunned the Celtics 119=117 in Boston, capping the Hawks’ comeback in the fourth quarter.

Coming off his 38-point, 13-assist effort, Young kept it going with 18 points in the first quarter.

But the Celtics finally clamped down on the Hawks star, whose heroics had forced Janet Jackson to postpone her scheduled Thursday concert until Friday to make room for Game 6.

Now, State Farm Arena is wide open for the summer.
