BOSTON - Throughout the postseason, the Boston Celtics had played their best basketball away from home.
Not anymore.
Jaylen Brown scored 27 points, Jayson Tatum added 26 and the Celtics rode the energy of a raucous TD Garden crowd Wednesday night to beat back another third-quarter onslaught by the Golden State Warriors in a 116-100 victory for a 2-1 lead in the NBA Finals.
Marcus Smart added 24 points and helped fuel a defensive performance that held the Warriors to 11 points in the fourth quarter - third fewest in an NBA Finals game in the shot clock era.
"Game 2, they brought the heat to us," Smart said. "For us, that left a bad taste in our mouth because what we hang our hat on is effort on the defensive end and being a physical team. It definitely woke us up a little bit."
Tatum said the fact the Celtics didn't hang their heads after the Warriors' third-quarter flourish is something they didn't always do in the regular season.
"I think that's when we are at our best, when we respond to tough situations. We respond to teams going on runs and things like that," he said. "I think we did that several times tonight."
Boston improved to 6-4 at home compared to 8-3 on the road this postseason. The Celtics haven't lost two straight games since the end of March.
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. Curry said it was similar to a play during the regular season in which Smart dove into Curry's legs while chasing a loose ball but "not as bad."
"I got caught - obviously in some pain, but I'll be all right," Curry said. "See how it feels tomorrow and get ready for Friday."
Klay Thompson broke out of a series 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.
"When you allow a team to get comfortable, especially in their home - in front of the home crowd, then it's tough," Warriors forward Draymond Green said.
Robert Williams III, who has been working his way back from knee surgery, finished with eight points, 10 rebounds and four blocks for Boston.
"We talked about it quite a bit, our group being resilient and being able to fight through a lot of things and at times when it's most needed being able to lock down on defense," Celtics coach Ime Udoka said. "We did in the fourth quarter,"
Game 4 is Friday in Boston. The previous 39 times teams have split the first two games of the title series, the winner of Game 3 went on to win it all 82% of the time.
Despite Curry's noticeable limp after the play with Horford, Warriors coach Steve Kerr said it was not why he pulled him from the game in the closing minutes.
"The injury didn't force him out of the game, but I took him out down 14 with two minutes left because we weren't going to catch up," Kerr said.
Feeding off the energy of a home crowd that jeered Green throughout his miserable night in the first NBA Finals game in Boston since 2010, the Celtics started fast and led by 18 points in the first half.
Coming off a Game 2 loss in which Boston turned the ball over 19 times, the Celtics' ball movement was much crisper in the half court, which led to open perimeter shots, favorable one-on-one matchups and driving lanes.
It left the Warriors scrambling at times, which contributed to three foul calls on Curry in the opening 24 minutes.
But as well as Boston played, it had its early lead erased in the third quarter by a Golden State 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 the Warriors in front 83-82.
Boston recovered to take a 93-89 edge into the fourth, then outscored Golden State 23-11 in the quarter.
In the first half, the Celtics led 56-39 before an 8-0 spurt in just 37 seconds by the Warriors trimmed the lead to 56-49 on a layup by Curry with 3:32 left in the second quarter. Boston flurried at the end of the period to take a 68-56 lead into halftime.
