The defending NBA champions held off the league’s hottest team on Tuesday night, with Jayson Tatum scoring 33 points and adding 12 rebounds to lead the Boston Celtics to a 120-117 victory over Cleveland and hand the Cavaliers their first loss after 15 straight wins to open the season.

Cleveland cut a 21-point deficit to two in the third quarter, and Donovan Mitchell hit a rainbow 3-pointer with 24 seconds left to make it a four-point game. Tatum sank one of two free throws, and then collided hard with Mitchell at the other end, leaving the Cavaliers guard on the floor in need of medical attention.

Mitchell eventually stepped to the line and sank both free throws, but Boston inbounded the ball without trouble and passed it downcourt for an easy Al Horford dunk to clinch it.

Tatum sank six of Boston’s 22 3-pointers and added seven assists for Boston’s third straight win.

Mitchell scored 35 points, and Evan Mobley had 22 points and 11 rebounds for the Cavaliers, who were the fourth team in NBA history to open the season with 15 wins in a row. The 15-game winning streak was the longest in franchise history.

The Celtics scored 19 of the last 26 points in the second quarter to turn a five-point lead into a 65-48 advantage at the break. Cleveland cut a 21-point deficit to two in the third.

The Celtics were 14 for 22 from 3-point range in the first half. They were up by five with 5:05 left when they hit four straight 3’s, and six in all down the stretch, opening a 65-48 halftime lead.

Knecht matches rookie 3s record for surging Lakers

Dalton Knecht tied the NBA's single-game rookie record with nine 3-pointers while scoring a career-high 37 points, and the Los Angeles Lakers beat the Utah Jazz 124-118 for their sixth consecutive victory.

LeBron James had 26 points and 12 assists, and Anthony Davis had 26 points and 14 rebounds as the Lakers improved to 7-0 at home. Austin Reaves added 17 points for the defending NBA Cup champions, who improved to 2-0 in group play this season.

The Lakers hadn't won six straight since February 2021, shortly after their championship run in the Florida bubble.

Lauri Markkanen scored 25 points for the Jazz, who have lost three straight. Keyonte George scored 10 of his 18 points in the fourth quarter, and Collin Sexton added nine of his 19 in the fourth.

Knecht hit 3-pointers on four consecutive possessions in the third quarter, getting the entire crowd on its feet. He scored 21 points in the third alone. His ninth 3 put LA up by 25 early in the fourth, but he didn't score again, and Utah trimmed the lead down the stretch.

Knecht tied the single-game rookie 3-pointer record shared by Rodrigue Beaubois (2010), Yogi Ferrell (2017) and Utah’s Keyonte George (2024).

Doncic helps Mavericks win in return

Luka Dončić returned to the lineup and scored 26 points, Klay Thompson added 19 and Kyrie Irving had 18 as the Dallas Mavericks beat the undermanned New Orleans Pelicans 132-91 in an NBA Cup game.

Doncic, who missed his first game of the season in Dallas' win at Oklahoma City on Sunday due to a knee injury, shot 10 of 16 overall and 3 for 8 from 3-point distance. He hit a pair of step-back 3-pointers midway through the fourth quarter giving Dallas a 111-75 lead.

Trey Murphy III, playing his fourth game this season because of hamstring issues, scored a season-high 19 points to lead the Pelicans. New Orleans was missing five of its rotation players. Two-time All-Star Zion Williamson missed his sixth consecutive game and is out indefinitely.

The Mavericks won their third straight, finishing with their highest point total of the season and largest margin of victory.

New Orleans has lost 11 of its last 13 games.

The Pelicans cut Dallas’ lead to 81-65 late in the third period before Irving followed a 25-foot 3-pointer with another seconds later, pulling up from 29 feet.
