BOSTON — Jayson Tatum had 39 points and 11 assists and the Boston Celtics pushed past the Utah Jazz 122-114 on Friday night.

Malcolm Brogdon added 19 points and Derrick White finished with 17 as Boston continued to gain ground on the Milwaukee Bucks in the race for the Eastern Conference’s top playoff seed.

Boston had 17 3-pointers, including five by Tatum.

The Celtics (54-24) are 1 1/2 games behind Milwaukee (55-22) and were coming off a 41-point win over the Bucks on Thursday. Milwaukee is off until Sunday, when it hosts the 76ers. The Celtics have four games remaining.

Talen Horton-Tucker led Utah with 28 points and eight assists. Walker Kessler added 20 points and 10 rebounds.

The Jazz (36-41) came in holding the 12th spot in the West and trailing 10th-place Oklahoma City by 1 1/2 games and 11th place Dallas by a half-game. The Mavericks were idle, but the Thunder lost at Indiana.

The Celtics took control in the second and third quarters, outscoring the Jazz 66-49. Boston also took advantage of a huge free throw discrepancy for most of the night. The Celtics connected on 21 of 22 attempts, compared to 13 of 14 for the Jazz. But 12 of Utah’s attempts were in the fourth quarter.

It was Boston’s players who took issue with the officiating with just over four minutes to play when Blake Griffin and Tatum were whistled for technical fouls 10 seconds apart. A minute after that, Griffin and Kris Dunn got tangled up after a Dunn foul, leading to a technical on Dunn. Tatum made the subsequent free throw, but Dunn had words for the officials, was assessed a second technical and ejected.

The exchange ultimately put the Celtics in front 117-101 with just over three minutes left.

With Al Horford (back stiffness) and Robert Williams (left knee) both out, the Celtics went small for the second straight game against the Jazz starting Tatum, Jaylen Brown, Griffin, White and Marcus Smart.

Horford and Williams also missed the first meeting between the teams earlier this month along with Smart – a win by Utah. This time, it was the Jazz missing several contributors, with three of their top four scorers – Lauri Markkanen (bruised left hand), Jordan Clarkson (sprained finger) and Collin Sexton (strained left hamstring) – all out.

NOTES: Utah didn’t take their first free throw until the 5:40 mark of the third quarter. Boston had attempted 16 to that point. … Utah had six turnovers in the first quarter. … The Celtics scored 19 points off 18 Jazz turnovers. … Former Red Sox star David Ortiz and Manager Alex Cora both sat courtside, as did rapper Jack Harlow and actor Casey Affleck. … Boston had its normal travel routine altered following Thursday’s win at Milwaukee when an issue pushed their return flight back from postgame to early Friday afternoon. They landed six hours before game time.
