The Los Angeles Clippers made the biggest NBA play-off return to run over the Golden State Warriors 135-131 to level their first-round.
The Warriors led 73-50 at half-time before a flurry from star point guard Stephen Curry, who hit 29 points, put the hosts 94-63 ahead in the third quarter in Oakland.
However, the Clippers cut the gap to 108-94, before outscoring the top seeds 41-23 in the final quarter.
Williams hit a jump shot over Klay Thompson to bring his side within a point and, after Thompson missed a three-point attempt, Landry Shamet converted one of his own to put the Clippers two points up with 16.5 seconds remaining.
Steven Curry missed a potential game-winning three before Clippers Centre Montrezl Harrell made two free throws to ensure victory.
Warriors centre man DeMarcus Cousins, who returned this season after a year out with a torn Achilles, suffered a quad injury in the first quarter.
Coach Steve Kerr had confirmed the injury as “significant” and said Cousins is “going to be out for a while”.
Elsewhere, the Philadelphia 76ers secured a dominant 145-123 victory over the Brooklyn Nets to level their Eastern Conference first-round series at 1-1.
Centre Joel Embiid scored 23 points and point guard Ben Simmons recorded a triple-double with 18 points, 10 rebounds and 12 assists for the third seeds.
