Pascal Siakam notched his first triple-double in over a year and the Indiana Pacers snapped the Philadelphia 76ers’ six-game winning streak, 134-122 on Thursday.

Siakam had 26 points, 13 rebounds and 10 assists, Myles Turner added 20 points and nine boards and Andrew Nembhard contributed 19 points as Indiana snapped a three-game skid.

Joel Embiid scored 31 points just three days after setting the franchise record with 70 points. He has scored at least 30 points in 21 consecutive games.

Despite playing without All-Star guard Tyrese Haliburton, the Pacers were never seriously threatened in this one. They opened with six straight points, quickly extended the lead to double digits and led by 17 before settling for a 73-61 edge at the break.

Porzingis injured in Celtics’ win

Jayson Tatum scored 26 points and Kristaps Porzingis had 19 before leaving with a sprained left ankle as the Boston Celtics rolled to a 143-110 rout of the Miami Heat.

Jaylen Brown added 18 points and Jrue Holiday had 17 for the NBA-leading Celtics, who registered their most-ever points against Miami, with the 33-point margin their most lopsided win in 172 meetings between the franchises, including playoffs.

Boston made 22 3-pointers, shot 63.8 percent from the field and held a 47-31 rebounding advantage.

Bam Adebayo and Tyler Herro scored 19 points apiece for the Heat, who dropped their season-high fifth straight.

Surging Knicks roll over Nuggets

OG Anunoby scored 26 points and Jalen Brunson added 21 as the New York Knicks sent the defending champion Nuggets to their worst loss of the season, 122-84.

Quentin Grimes had 19 points, Julius Randle scored 17 and Donte DiVincenzo chipped in 16 as the Knicks won their season high-tying fifth in a row and improved to 11-2 since Anunoby was acquired from Toronto.

Nikola Jokić led Denver with 31 points and 11 rebounds, but the Nuggets had a three-game winning streak stopped. Their previous biggest loss was a 119-93 defeat to Oklahoma City on Dec. 29.

New York was 15 of 38 from 3-point range, while Denver was 5 of 26.
