Jaylen Brown scored 27 points, Jayson Tatum added 26 and the Boston Celtics beat back another third-quarter onslaught by the Golden State Warriors in a 116-100 victory Wednesday night that gave them a 2-1 lead in the NBA Finals.

Marcus Smart added 24 points and helped lead a defensive effort that held the Warriors to 11 points in the fourth quarter,

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.

Klay Thompson broke out of a finals slump and finished with 25 points and five 3s. But the Warriors’ shooting couldn’t save them on a night the more athletic Celtics outmuscled them for a 47-31 rebounding advantage,

But as well as Boston played, it had its early lead erased in the third quarter by a Warriors seven-point possession that included a four-point play by Curry when he drew a flagrant 1 foul on Horford and 3-pointer by Otto Porter Jr to put Golden State in front 83-82.

Boston recovered to take a 93-89 edge into the fourth. The Celtics got the lead back up to 102-91 in the fourth and outscored Golden State 23-11 in the quarter.
