Keifer Sykes hit a go-ahead 3-pointer with 1:41 left in overtime and a layup the next possession, Chris Duarte scored 27 points and the undermanned Pacers beat Stephen Curry and the Warriors 121-117 on Thursday night.
Golden State got one last chance with 6.4 seconds left after a jump ball and Klay Thompson checked in but couldn't get a shot off.
Curry scored 39 but none in overtime, missing a 3 from the top of the arc with 16.5 seconds left. He had a tying layup with 2:44 left and four free throws in the final 34.5 seconds of regulation, but Golden State surrendered Justin Holiday's tying 3 with 6 seconds left to send the game into OT.
Duarte hit clutch jumpers late in regulation as the determined Pacers hung tough on a night they were missing the starting backcourt duo of Malcolm Brogdon and Caris LeVert, along with starting center Domantas Sabonis because of injuries.
Juan Toscano-Anderson, who had a key 3 with 3:19 to go, rebounded Torrey Craig's miss with 15.7 seconds left and Curry converted free throws.
Indiana center Goga Bitadze was ejected with 6:44 left following his second technical after fouling Gary Payton II, who went over the 6-foot-11 center for a left-handed slam and also was whistled for a technical.
Thompson drove to the basket for a pretty reverse layup in the second quarter and again showed signs of his old dominant self after returning earlier this month from a 2 1/2-year absence following surgeries on his left knee and right Achilles tendon. He missed all seven of his 3-point tries and Golden State's players aside from Curry were 0 for 14 from deep until Damion Lee connected with 40 seconds left in the third.
Curry had 18 points by halftime to help Golden State build a 63-55 lead and wound up 12 of 27 with six 3-pointers. Kevon Looney grabbed 15 rebounds for his career-best fourth straight game with double-digit boards. DeMarcus Cousins was the last Warriors player with 10 or more rebounds in four straight games, doing so in five in a row from Feb. 12-28, 2019, according to Elias.
Indiana snapped a four-game losing streak with a 111-104 road win against the Lakers on Wednesday. The Pacers take on the top two teams in the Western Conference in consecutive games when they play at Phoenix on Saturday.
