Boston — Isaiah Thomas scored 17 of his 38 points in the fourth quarter and the surging Boston Celtics beat the Los Angeles Lakers 113-107 on Friday night for their sixth consecutive victory.

Al Horford added 11 points, eight rebounds and eight assists for the Celtics. Thomas logged his 34th straight game with 20 or more points and is six shy of John Havlicek’s franchise-record streak.

Jae Crowder had 18 points, Jaylen Brown added 12 and Terry Rozier scored 10 for Boston (32-18).

D’Angelo Russell led the Lakers with 20 points. Lou Williams scored 20, Larry Nance Jr. had 18 and Nick Young 17 as Los Angeles (17-36) lost for the fifth time in six games.

Boston and Los Angeles both began the night with 3,252 wins, tied for the most in NBA history. Before their loss, the Lakers held at least a share of the league’s all-time victories mark since 2001.

With Toronto’s loss to Orlando earlier in the night, Celtics coach Brad Stevens was assured his spot as coach of the Eastern Conference in the NBA All-Star Game in New Orleans next Sunday.

Thomas scored seven points in the third as the Celtics broke the game open and led by as many as 16. The Lakers cut it to 82-74 after three but couldn’t get the deficit below six.

Boston opened the game on a 7-0 run before Russell’s 3-pointer put the Lakers up 15-14 with 7:34 left in the first quarter. Rozier’s buzzer-beating 3 drew the Celtics to 30-29 after one. Thomas had 12 points in the period.

Rozier’s floater a minute into the second put the Celtics ahead for good, and Boston stretched its lead to 62-51 at halftime.

The Lakers and Celtics meet again March 3 in Los Angeles.

Notes: G Avery Bradley (sore right Achilles) missed his ninth consecutive game. Bradley felt good after working out and doing some on-court work on Friday. “We’re still progressing at a conservative rate,” Stevens said. “We want him feeling 110 percent.” … F Kelly Olynyk played after sitting out Wednesday in Toronto with a sore left shoulder.

Thunder 114, Grizzlies 102

Oklahoma City — Russell Westbrook scored 19 of his 38 points in the fourth quarter and had a triple-double to lead Oklahoma City past Memphis.

Westbrook also had 13 rebounds and 12 assists. It was his 25th triple-double this season and the 62nd of his career. His season total is the most in the NBA since Wilt Chamberlain had 31 during the 1967-68 season.

Pistons 116Timberwolves 108

Auburn Hills, Mich. — Marcus Morris scored a career-high 36 points, and Detroit held off Minnesota.

Jon Leuer added a career-high 24 points for Detroit, which won despite 5-for-20 shooting from its starting backcourt of Reggie Jackson and Kentavious Caldwell-Pope. Morris scored 13 of his points in the third quarter.

Pacers 106, Nets 97

New York — Paul George scored 24 points and grabbed 11 rebounds, Jeff Teague had 24 points and Indiana beat Brooklyn.

Magic 102, Raptors 94

Orlando, Fla. — Serge Ibaka scored 20 points and grabbed 12 rebounds while Evan Fournier added 20 points and 10 rebounds to help Orlando beat Toronto.

It was the second time in less than a week that the struggling Magic have defeated Toronto. And like Sunday’s win, this one was close throughout and wasn’t decided until the late.
