Jayson Tatum’s triple-double leads the Celtics to elimination of the Bulls

Tatum finished the game with 43 points, 16 rebounds and 10 assists. He made 9 of his 15 3-pointers and completed the trifecta with a lob pass to Kristaps Porzingis, who scored with a jump shot.

Tatum was 16 for 24 from the field as the Celtics shot 48.5 percent and the Bulls bullied inside, scoring a season-high 60 points. Tatum also became only the second player in NBA history, joining James Harden, with at least 40 points, 15 rebounds, 10 assists and 9 3-pointers in a game.

Porzingis added 22 points while Jaylen Brown scored 19 points. Nikola Vucevic scored 19 points for Chicago, which lacked the strength and assertiveness of Thursday’s win.

Tatum appeared to be in full form in the third quarter as the Celtics took control of a back-and-forth game. He scored 13 points in a 19-8 quarterfinal run that gave Boston a 93-77 lead.

The Celtics ditched their usual 3-point emphasis and used ball movement and cuts to score at the rim. Tatum stunned the crowd with a fierce dunk over a leaping Jalen Smith as the Celtics pulled away.

The Bulls, a confusing team because of their ability to beat elite teams and lose to weak teams, didn’t play with the vigor or passion they did Thursday. At the end of the third quarter, they missed 23 of 39 2-point shots, including several layups and short jumpers.

Zach LaVine hit all four of his 3-point attempts but missed all six of his 2-point attempts. The Celtics played a matchup zone that seemingly cost the Bulls their life, and they closed the game with a 14-2 run to start the fourth period and take a 28-point lead. The Celtics demanded revenge.

Before the game, Celtics coach Joe Mazzulla said his club had achieved three of its four main goals in the previous meeting on Thursday, but he would not reveal that single flaw. But it was obvious that the Bulls had caught the attention of the Celtics after their 117-108 win, especially with their physicality.

Boston was more focused defensively in the first half than it was on Thursday. The Bulls shot just 40 percent in the first half, including 9 of 25 from the 3-point line. LaVine, who fueled the Celtics with 36 points in their last meeting, mustered just 11 on nine shots in the first half. Patrick Williams, who made four 3-pointers on Thursday, added 11 on 4-for-8 shooting added.

Chicago went on a 6-0 run in the first minute of the second quarter to take a 31-28 lead before the Celtics countered with a 9-0 lead and took control.

Kristaps Porzingis, looking healthier as the games go by, added a three-pointer and free throws to the run. Boston’s lead grew to 61-49 with a 10-2 run when Jaylen Brown scored a layup followed by a steal and dunk during the rally.

One of the Celtics’ problems early in the season was the end of quarters, and they were held scoreless for the final 1:43 of the first half, a stretch in which Tatum suffered a backcourt injury. The Bulls regained some of the momentum with the final five points, with LaVine cutting the deficit to 61-54 with a line-drive 3-pointer.

Chicago is second to the Celtics in 3-point attempts and outscored Boston 25-22 in the first half. Leading despite losing the 3-point battle 27-18, the Celtics opted to attack the paint and capitalize on Chicago’s lack of rim protection. They scored 34 of their 61 points in the first half in the stadium.

If you take away Porzingis and Payton Pritchard, the Celtics are 2 for 16 from the 3-point line. On Thursday they set a club record with 42 missed 3-point shots, but their focus on scoring inside was crucial to their lead at halftime.

The Celtics kept their cool in the first half after struggling in the game on Thursday. Coach Joe Mazzulla was fined $35,000 for attempting to address official Justin Van Duyne after the loss, while Brown and Tatum each experienced technical problems in the fourth quarter. The Celtics met with officials Saturday morning about controlling their emotions.
