Marcus Smart added 24 points.
Stephen Curry led Golden State with 31 points and six 3-pointers. He had 15 points in a 33-25 third quarter by the Warriors but was hurt late in the fourth after Al Horford rolled into his leg on a loose ball.
It was similar to a play during the regular season in which Smart dove into Curry’s legs while chasing a loose ball.
Klay Thompson broke out of a finals slump and finished with 25 points and five 3-pointers.
Game 4 of the best-of-seven series is on Friday (Saturday NZT) in Boston.
