Derrick White scored 38 points on 15-for-26 shooting, including 8-for-15 success from 3-point range, and the Boston Celtics cruised to a 102-88 win over the host Miami Heat on Monday night.

Jayson Tatum added 20 points and 11 rebounds for the Celtics, who seized a 3-1 lead in the best-of-seven Eastern Conference quarterfinal series. Jaylen Brown finished with 17 points.

White, a 29-year-old guard, produced a career-high point total — regular season or postseason.

Bam Adebayo led the Heat with 25 points, 17 rebounds and five assists. Tyler Herro contributed 19 points and Caleb Martin had 18 for Miami, which will try to stave off elimination in Game 5 of the series on Wednesday night in Boston.

The victory came with a potential injury cost for top-seeded Boston.

Celtics center Kristaps Porzingis injured his calf in the first half and did not return. Porzingis reportedly will undergo tests on Tuesday, but indications are that he did not sustain a significant Achilles tendon injury.

Down by 28 in the third quarter, Miami opened the fourth on a 19-10 run to pull within 13. That surge included a 7-0 run for the Heat that featured a 3-pointer by Martin, a mid-range jump shot by Herro and a basket by Adebayo.

The Celtics led 81-59 at the end of the third quarter.

White gave Boston its biggest lead of the game with three minutes to go in the third quarter, when his floater made it 75-47.

Boston took a 53-36 lead into halftime.

The Celtics jumped to a 34-24 advantage at the end of the first quarter. Tatum drained a 3-pointer to give Boston a 14-point lead with 1:21 left in the period, but Adebayo finished the session with back-to-back baskets to cut the deficit to 10.

Stingy defense and cold shooting proved prominent for both teams during the second quarter. Boston managed 19 points in the quarter and Miami scored only 12.

The Heat shot 5-for-22 overall (22.7 percent) and 1-for-7 from beyond the arc in the second. Boston shot 7-for-20 (35 percent) from the field and 4-for-9 from long distance.
