The defending NBA champions took the lead in the first quarter and survived a lull in the fourth quarter.
Less than 24 hours after rallying from a 24-point deficit in Philadelphia, the Warriors did not experience any similar problems in the first half Sunday. Golden State led for most of the final 42:08, held a 22-point lead at halftime and a 28-point edge early in the third before the Nets got close.
Curry, who scored 20 of his 35 points Saturday in the Warriors' 47-point third quarter, finished with his 137th regular-season 30-point game Sunday. He shot 14 of 24 from the floor and hit four 3-pointers. Curry also finished with his 19th point/rebound double-double and his 10th career game with 30 points and 10 rebounds.
The Warriors (13-4) won for the ninth time in 10 games despite missing Kevin Durant. The star forward sat out with a sprained left ankle, missing a game for the second time this season.
Golden State's Klay Thompson hit a 3-pointer for the 71st straight game and recorded his third career double-double with 23 points and 10 rebounds.
Allan Crabbe led the Nets (6-10) with 25 points. Spencer Dinwiddie added 21 for Brooklyn, which shot 35.8 percent and lost for the eighth time in 11 games. Rondae Hollis-Jefferson (16 points, 12 rebounds) and DeMarre Carroll (15 points, 11 rebounds) each had double-doubles for Brooklyn.
Curry picked up his fifth foul with seven seconds left in the third quarter and was on the bench when a sweeping hook shot by rookie Jarrett Allen sliced the lead to 104-96 with 6:43 remaining.
It was 105-99 on a 3-pointer by Dinwiddie with 4:55 remaining, but Curry banked in a layup. Still, Curry's final hoop was not enough to clinch it as the Nets got it to 107-102 on a Crabbe free throw with 3:44 left.
Curry fouled out with three minutes remaining when he was called for a charge on Quincy Acy on a drive through the lane.
The Nets were within 114-109 on a 3-pointer by Crabbe with 71 seconds remaining, but Dinwiddie missed a 3-pointer on Brooklyn's next possession, and the Warriors iced the game at the line.
