Warriors 116, Thunder 115: Andre Iguodala buried a deep jumper as time expired to cap a 14-point, nine-assist outing as Golden State stunned visiting Oklahoma City.

Klay Thompson scored 27 points, Stephen Curry added 22 points and nine assists and David Lee scored 20 for the Warriors, who improved to 4-0 at home. Golden State hit 13 of its first 17 3-point attempts and finished 14-of-23 from beyond the arc, led by Thompson’s 6-of-9 effort.

Russell Westbrook scored a game-high 31 points and nearly had the winner when his 3-pointer put the Thunder on top with 2.3 seconds left. Serge Ibaka added 27 points and 13 rebounds while Kevin Durant collected 20 points, eight assists and seven rebounds while battling foul trouble for Oklahoma City.

The Warriors led by as many as 14 points after Lee’s bucket with 7:11 left but allowed the Thunder to make one more big run. Durant’s 3-pointer chopped it down to 108-100 with 5:30 left and Thabo Sefolosha drained one from beyond the arc to pull Oklahoma City within three with 3:18 on the clock.

Curry missed a long jumper that would have made it a two-possession game with 14 seconds left and Durant grabbed the rebound, finding Westbrook for a deep rainbow 3-pointer from the right wing to give the Thunder a 115-114 lead. Golden State called timeout and Iguodala took the inbounds pass on the right side, rising up and burying the buzzer-beater over Sefolosha from two feet inside the arc for the win.

The first quarter alone saw three ties and 11 lead changes while Thompson and Curry combined to go 5-for-6 from beyond the arc. The Thunder responded to every big basket, including one sequence in the second quarter where Curry and Jeremy Lamb traded 3-pointers, and it went into the break knotted at 62.

Golden State began to gain some separation in the third quarter as Curry banged home a deep 3-pointer to force a timeout and put the Warriors up 84-77 with 4:56 left in the period. The lead swelled to 93-82 on Harrison Barnes’ 3-pointer just under four minutes later and Golden State took a nine-point lead into the final stanza.
