Boston— Jaylen Brown scored 23 points, Jayson Tatum added 22 and the Boston Celtics beat the New York Knicks, 110-89, on Tuesday night.

Kyrie Irving added 20 points and seven assists. Al Horford finished with 13 points and 13 rebounds.

After dropping their first two games to open the season, the Celtics have won two straight. The Knicks remain winless through their first three games.

According to Elias Sports Bureau, Tatum and Brown are the first Celtics’ duo ever to score 20-plus points at 21 years or younger in the same game in team history.

Enes Kanter led New York with 16 points and 19 rebounds. But he got most of them in a first half in as his team struggled mightily from the field. The Knicks scored the first basket of the night, but never led again. They shot just 42 percent and went 1 of 12 from the 3-point line.

Boston played without guard Marcus Smart, who sat out his second straight game with a sprained left ankle.

But they didn’t need him. The Celtics played like a team coming off four days’ rest, taking as much as a 25-point lead late in the second quarter.

New York never recovered.

Knicks coach Jeff Hornacek said before the game that Tim Hardaway Jr. had been playing through an ankle injury.

He took a couple of hard spills, but still logged 28 minutes. He finished with six points, connecting on just 2 of his 11 shots.

Notes: This is the third time this season the Celtics have scored 100 or more points. … Had five of their seven blocks in the first half. … Coach Brad Stevens said Smart remains day to day, but expects that he will travel with the team on its upcoming road trip.

Cavaliers 119, Bulls 112

Cleveland— LeBron James scored 34 points in a rare start at point guard and Cleveland, using another early season lineup, awakened after a sluggish first half.

Although he often handles the ball and runs Cleveland’s offense, James had not officially been listed as a guard since 2012 with Miami. He added 13 assists, including a no-look, behind-the-back dish to Jae Crowder for a 3-pointer during Cleveland’s 15-3 spurt in the third quarter.

Kevin Love had 20 points and 12 rebounds, and Dwyane Wade, who asked Cavs coach Tyronn Lue to take him out of the starting lineup, came off the bench and added 11 points.

Justin Holiday scored 25 and rookie Lauri Markkanen 19 for Chicago, which made a season-high 17 3-pointers.

The 7-foot Markkanen became the first player in NBA history to make 10 3-pointers in his first three career games.

Magic 125, Nets 121

Orlando, Fla. — Aaron Gordon scored a career-high 41 points, including the go-ahead 3-pointer with 35 seconds remaining, and grabbed 12 rebounds to lead Orlando over Brooklyn.

Evan Fournier added 28 points in game that went back and forth late in the fourth quarter. He finished the scoring with two free throws with 15.5 seconds to play.

D’Angelo Russell scored 27 points for the Nets, while DeMarre Carroll had 19 and Rondae Hollis-Jefferson 18.

Pacers 130, Wolves 107

Minneapolis — Victor Oladipo scored 28 points and Cory Joseph added 21 to lead hot-shooting Indiana past Minnesota.

Darren Collison had 15 points and 16 assists, Bojan Bogdanovic scored 19 points and Domantas Sabonis had 15 points and 11 rebounds for the Pacers, who shot 67 percent from the floor.
