The Boston Celtics secured a 1–0 lead in the 2024 NBA Finals after taking care of business on their home court against the Dallas Mavericks on Thursday night in Game 1, 107–89.

The Celtics jumped out to a huge first-half lead, pulling ahead by as many as 29 points during the second quarter before heading into halftime up by 21. Although the Mavericks clawed back to within eight points in the third quarter, Boston was able to re-extend its advantage and shut the door on the series opener.

Kristaps Porzingis was sensational in his return to the lineup, making his first appearance for the Celtics since April 29, when he sustained a calf injury against the Miami Heat in the first round of the playoffs. The 28-year-old scored 20 points off the bench, providing a major offensive boost for the team.

Jaylen Brown and Jayson Tatum combined for 38 points, coming up with big plays on both ends of the floor as they helped guide their team to a Game 1 win. Tatum recorded a double-double with 16 points and 11 rebounds, while Brown came away with three steals and three blocks, alongside a team-high 22 points.

As for the Mavs, Luka Doncic's first taste of the NBA Finals was not what he'd been hoping for. The 25-year-old played well, but it wasn't enough to keep Dallas close. He scored a game-high 30 points while adding 10 rebounds and just one assist. Backcourt mate Kyrie Irving struggled in the loss, shooting 6 for 19 in a 12-point outing.

Dallas faltered as a whole from beyond the arc, making just 7 of 27 attempts from three-point range. Boston was vastly better, shooting 16 for 42 from deep, a difference which showed up on the scoreboard. The Mavericks' 89 points were their fewest this postseason.

Dallas will look to bounce back in Game 2, which is set for Sunday at 8 p.m. ET from TD Garden.
