The NBA champion Boston Celtics crushed the Golden State Warriors 125-85 on Monday as current league leader Cleveland romped past the Phoenix Suns.

Golden State had not lost by 40 at home since Jan 15, 1985.

Jayson Tatum scored 22 points with nine rebounds and seven assists before sitting out the entire fourth quarter of the Celtics' dominant victory in San Francisco.

Kristaps Porzingis added 18 points and Jaylen Brown chipped in 17 for Boston, who took full advantage of the absence of Draymond Green, the latest Warriors injury victim after he strained his left calf on Saturday.

"Those are some of the tricky games in the NBA, when (teams) have some star players out, other guys get a different role," Tatum said. "We fell victim to that a couple of times this year, so (we were) just trying to lock in from the beginning."

Up by 15 at halftime, the Celtics erupted for 43 points in the third quarter.

Stephen Curry scored 18 points to lead the Warriors and Moses Moody added 13 off the bench — the only Golden State players to score in double figures.

It was just one of the lopsided results as the NBA marked the Martin Luther King Jr holiday with a day-long slate of games.

Donovan Mitchell scored 33 points to fuel the Cavaliers in a 118-92 victory over the Phoenix Suns.

Injury absences of Evan Mobley, Isaac Okoro and Caris LeVert did nothing to slow the Cavs, who led by as many as 32 on the way to boosting their league-best record to 36-6.

"The biggest thing was this was a group effort," Mitchell said. "Everybody contributed at a high level."

Kevin Durant scored 33 points with seven rebounds to lead the Suns, but Devin Booker — who had scored at least 30 points in the Suns' last five games — was held to 15 points on six-of-14 shooting.

Grizzlies rally

In Memphis, Jaren Jackson Jr scored 24 points and grabbed 11 rebounds to help the Memphis Grizzlies rally from a 16-point deficit to beat the Minnesota Timberwolves 108-106.

Desmond Bane added 22 points and Ja Morant scored 19 for Memphis, who was still down by five going into the fourth quarter and took its first lead of the second half on Bane's floater in the lane with 3:21 remaining.

"It was ugly from the start, but we kept competing and found a way down the stretch," Bane said.

Anthony Edwards scored 32 points to lead the Timberwolves, but missed a potential game-winning three-pointer as time expired.

New York's Jalen Brunson scored 34 points to propel the Knicks to a 119-110 victory over the Atlanta Hawks.

Trae Young scored 27 points, leading seven Hawks players to score in double figures, but Atlanta saw its three-game winning streak end and fell to 22-20.

The Detroit Pistons shook off back-to-back home losses with a 107-96 victory over the Rockets in Houston.

Cade Cunningham scored 32 points with nine rebounds and seven assists and Jalen Duren added a double-double of 16 points and 14 rebounds with four steals and two blocked shots.

In Charlotte, LaMelo Ball and Miles Bridges scored 23 points apiece as the Hornets used a balanced scoring effort to hold off Kyrie Irving and the Dallas Mavericks 110-105.

Irving scored 14 of his 33 points in the final frame and Daniel Gafford finished with a career-high 31 points and 15 rebounds, but with Luka Doncic still sidelined by a calf injury the Mavericks lost for the fourth time in their last five games.
