Boston poured in 16 three-pointers in a dominant 110-97 victory over the Miami Heat on Thursday that kept the Celtics alive in the National Basketball Association championship chase.

For the second straight game, the Celtics fended off elimination, cutting the deficit in the best-of-seven Eastern Conference finals to 3-2 with the wire-to-wire triumph.

Miami will get another chance to close it out when they host game six on Saturday. The Celtics will be trying to take one more step toward becoming the first NBA team to rally from a 3-0 deficit to win a best-of-seven playoff series.

"The only thing that can stop us is us," Celtics forward Jaylen Brown said in an on-court interview.

Before a rapturous, raucous crowd at TD Garden in Boston, the Celtics looked every inch the favorites they were before the series started — before the upstart eighth-seeded Heat grabbed the first two games in Boston, then embarrassed the second seeds in game three.

Four Celtics starters scored more than 20 points, with Derrick White leading the way with 24 on a night when he made six of eight attempts from three-point range.

"Got some good looks and was able to knock them down, and just kind of rolled with it," said White, who said the Heat's defensive focus on Brown and fellow star wing Jayson Tatum gave him more room to operate.

Marcus Smart added 23 and had five steals while Brown and Tatum scored 21 apiece.

More importantly, the energetic Celtics harried the Heat into 16 turnovers that led to 27 Boston points.

They had 17 second-chance points compared to Miami's seven.

"Tonight we were the tougher playing team," Brown said. "We set the tone from start to finish."

Boston was locked in on both ends of the floor from the opening tip-off, roaring to a 23-7 lead in a matter of minutes.

After Tatum was whistled for a technical foul with 8:43 in the first quarter, the Celtics responded with three consecutive three-pointers.
