Jaylen Brown added one more to his highlight tape.

The Celtics star brought the home crowd at TD Garden to its feet when he dunked over the Mavericks’ Daniel Gafford in one of the high points of Boston’s 107-89 blowout win in Game 1 of the NBA Finals.

Brown, dribbling the ball on the offensive end of the court with a little bit over 10 minutes left in the first half, got a screen before dribbling around Luka Doncic and going fast into the paint.

He leaped past a jumping Kyrie Irving before dropping the hammer down over Gafford, who failed to get the block down.

“Brown goes inside, oh what a slam from Jaylen Brown!” ESPN play-by-play announcer Mike Breen said on the call.

It was part of a huge night for Brown, who scored 22 points with six rebounds, three steals and three blocks, including memorable rejection against Irving in the third quarter that sent the Boston fans into a frenzy again.

Brown said the key came in the third quarter when Boston rattled off a 14-0 run to put the game out of reach.

“That’s when the game started,” Brown told reporters after the game, according to the Associated Press.

Brown added that having Kristaps Porzingis back in the lineup was huge after he suffered a calf injury in the first round of the playoffs.

The big man scored 20 points in his return to action after over a month away from the court.

“Kristaps had a monster game for us,” Brown said, according to ESPN. “Just his presence shooting the ball and then him being able to attack those switches and mismatches, he made ’em pay every time, and that’s what we need going forward in the series.”

Doncic scored 30 points to lead the Mavericks, but Irving, who received plenty of boos from Celtics fans, was held to 12 points on 6-for-19 shooting from the field.

Game 2 is on Sunday at 8 p.m. in Boston.
