National Basketball Association overall leader Boston delivered a devastating and historic performance in routing the Golden State Warriors, 140-88, stretching the Celtics' win streak to 11 games on Sunday.

It was the third-largest blowout victory in Celtics history, a legacy dating to 1946.

Boston's Jaylen Brown scored 25 of his 29 points in a record-shattering first half while Jayson Tatum celebrated his 26th birthday by scoring 22 of his 27 points during the first two quarters of domination.

"It's up there. Great birthday. Got to do what I love in front of the best fans in the world and get a win," Tatum said.

The Celtics became the first club in NBA history to win three games in the same season by 50 or more points. The Celtics routed Indiana 155-104 in November and last month blasted Brooklyn 136-86, taking both in Boston.

Despite Latvian big man Kristaps Porzingis being sidelined by a left quad bruise, the host Celtics seized an 82-38 lead after the second quarter, their largest half-time edge in team history and the Warriors' largest-ever half-time deficit.

"It was a lot of fun," Boston's Derrick White said.

"It was a good start. You never expect something like that to happen."

The Celtics made 10 3-pointers in the first quarter, their most in any quarter this season, and closed the period on a 23-1 run over six minutes to seize command at 44-22.
