Porzingis hits a game-tying 3-pointer in his Celtics debut, helping Boston defeat the Knicks 108-104

Kristaps Porzingis made a tiebreaking 3-pointer with 1:29 left and scored 30 points in a strong Celtics debut, Jayson Tatum had 34 points and 11 rebounds and Boston beat the New York Knicks 108-104 on Wednesday night in the season opener for each team.

Porzingis finished with eight rebounds and four blocked shots against his original NBA team, showing why his new one is considered one of the NBA Finals favorites after acquiring the 7-foot-3 center and Jrue Holiday during the offseason.

Holiday had a key basket after the Knicks opened a six-point lead with 3:40 left before Porzingis scored Boston’s next nine points, including the 3-pointer that snapped a 101-all tie.

Holiday scored nine points. Derrick White had 12 for the Celtics, and Jaylen Brown had 11 points, six rebounds and five assists.

RJ Barrett and Immanuel Quickley each scored 24 points for the Knicks, who started slowly but opened the fourth quarter with a 13-2 run to take their first lead of the game. They couldn’t hold on against one of the NBA’s best teams.

Porzingis was the No. 4 pick by the Knicks in 2015 and was an All-Star in 2017-18, but soured on the organization while recovering from a torn ACL. He was traded during the 2018-19 season.

Porzingis has developed into the player the Knicks had hoped, averaging a career-best 23.2 points last season for Washington.

He had three 3-pointers and 15 points in the first quarter, which ended with Boston up 30-18. But he didn’t take a shot in nearly eight minutes of playing time in the second and the Knicks cut it to 51-46 at the half.

Tatum scored Boston’s first nine points of the second half to push the lead back into double digits. The Knicks would charge back to tie it midway through the third on Jalen Brunson’s 3-pointer, but the Celtics went back ahead 82-73 as Porzingis beat the buzzer with a follow shot.

With Porzingis starting, Al Horford came off the bench for the first time since doing so six times in 2019-20 in Philadelphia. He had only done it only four other times in more than 1,000 career games, for Atlanta as a rookie in 2007-08.

Horford finished with eight points and seven rebounds.

Brunson struggled to 15 points on 6-for-21 shooting. Julius Randle shot 5 for 22 en route to his 14 points, 11 rebounds and seven assists.

The Knicks missed 11 of their first 13 shots, making two dunks and nothing else.
