The Golden State Warriors almost blew a five-point lead in the final minute as Harrison Barnes missed a buzzer-beater as the reigning champions levelled their first round series with the Sacramento Kings after a 126-125 Game 4 win on Sunday.

The Warriors led 126-121 heading into the final 60 seconds but gifted the Kings an avenue back in after Stephen Curry called for a timeout when they had none left at Chase Center.

Malik Monk scored the subsequent free-throw before De'Aaron Fox's three-pointer cut the margin to one point.

Curry then missed a pullup shot with 14 seconds left but the Kings could not capitalise with the final possession after a timeout, when a double-teamed Fox found Barnes open before his attempt rimmed out.

Reigning NBA Finals MVP Curry finished with 32 points on 11-of-22 shooting with five-of-11 from beyond the arc, along with five rebounds and four assists.

Klay Thompson had 26 points with four three-pointers and Jordan Poole added 22 points, while Draymond Green returned from a one-game ban off the bench with a strong display, holding the Kings to five-of-15 as primary defender.

Clutch Player of the Year Fox did everything but hit the final shot, scoring 38 points on 14-of-31 shooting with four three-pointers.

Keegan Murray added 23 points with five-of-seven three-point shooting and Domantas Sabonis was down on his usual output with 14 points, seven rebounds and eight assists.

The Warriors squared the series up at 2-2 ahead of Game 5 in Sacramento on Wednesday. Golden State are 35-8 at home across the regular and postseason but are 11-32 on the road.

Jayson Tatum and Jaylen Brown scored 31 points each as the Boston Celtics pulled 3-1 clear in their first-round series against the Atlanta Hawks with a 129-121 road win.

The Celtics led nearly the entire game, holding off a 68-point Hawks' second half, with Tatum and Brown combining for Boston's final 16 points to round out the win.

Tatum's 31 points came on eight-of-20 shooting from the field including four-of-13 three-pointers, with seven rebounds and three blocks. Brown scored 12-of-22 from the field with three triples.

Trae Young had a strong game for Atlanta with 35 points and 15 assists, while De'Andre Hunter added 27 points and Dejounte Murray scored 23 with nine rebounds.

Donovan Mitchell had a poor game, managing only 11 points on five-of-18 shooting, with Darius Garland stepping up for 23 points and 10 assists.

But the Knicks were too strong, with R.J. Barrett supporting Brunson with 26 points, while Josh Hart had 19 points and seven rebounds. Brunson shot five three-pointers, while Julius Randle sat out the fourth quarter, scoring on seven points fo the game.
