Lee started the scoring with an 18-footer and Andre Iguodala followed with a layup and a dunk for a 6-0 lead. Jerryd Bayless then hit a fadeaway jumper for Boston, but Golden State got the next six points on dunks by Curry and Thompson and a layup by Lee.
The game was still competitive when Bayless’ two free throws cut Golden State’s lead to 42-33 with 5:55 left in the first half. Then Thompson’s 3-pointer began a 19-7 run that gave the Warriors a 61-40 lead at halftime.
Baskets by Lee and Andrew Bogut made it 49-33 before Rajon Rondo sank a free throw and Jared Sullinger made two for Boston. But then Golden State scored the next six points on a short jumper by Lee, a dunk by Iguodala and a 16-footer by Curry.
A 3-pointer by Green cut the margin to 55-38, but Curry followed with a 3-point play. Rondo answered with a layup before Iguodala finished the first-half scoring with a 3-pointer with 10 seconds remaining.
The sloppy Celtics committed 12 turnovers in the first half, leading to 15 points, while the Warriors turned the ball over just twice, leading to two points.
“What hurt us more than maybe anything were the turnovers in the first half that led to the dunks that got those guys going,” Stevens said. “I didn’t think our effort was great.”
The Warriors took their biggest lead, 31 points, when two straight baskets by Thompson made it 80-49 with just over five minutes left in the third quarter.
“They’re hitting their stride a little bit,” Stevens said.
Now the Warriors head home for 13 of their remaining 20 games.
“We took care of business on the road,” Lee said. “Our thought is we shouldn’t lose any more games at home.”
