The Warriors scored the first six points, led 12-2 with just over five minutes gone and stayed ahead by at least 20 points throughout the second half. It was the final game of a six-game road trip that saw the Warriors go 4-2.
Golden State had an easy time against one of the NBA’s worst teams one night after beating one of the best. Thompson’s 12-foot turnaround with 0.6 seconds left had given the Warriors a 98-96 win at the Indiana Pacers, the league’s top team at home.
Former Celtic Jordan Crawford had 15 points and Stephen Curry added 14 for the Warriors (38-24), who won for the seventh time in nine games.
Kelly Olynyk scored 19 points for Boston (20-41), which dropped its seventh game in its past eight.
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.
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.
The Warriors took their biggest lead, 31 points, when consecutive baskets by Thompson made it 80-49 with just over five minutes left in the third quarter.
Warriors coach Mark Jackson rested his starters in the fourth quarter.
