The LA Clippers produced the biggest comeback in NBA play-off history after recovering from 31 points down to stun the Golden State Warriors and level their first-round series up at 1-1.

Golden State, the two-time reigning NBA champions, looked to be cruising to victory at Oracle Arena as they built a 94-63 lead midway through the third quarter.

However, the Clippers roared back in stunning fashion, scoring 72 points in the final 20 minutes to defeat their hosts 135-131 in a thrilling game two.

Lou Williams paced the Clippers with 36 points and 11 assists while team-mate Montrezl Harrell also recorded a double-double after pouring in 25 points and grabbing 10 rebounds.

Stephen Curry led the Warriors with 29 points but it was not enough and, to add injury to insult, Golden State also lost centre DeMarcus Cousins to what coach Steve Kerr has described as a "pretty significant" quad injury early on.

Records were also broken in the night's other game as the Philadelphia 76ers thrashed the Brooklyn Nets 145-123 to also level their series at 1-1.

Philadelphia scored 51 of their points in a remarkable third quarter, which was a post-season record for the 76ers and equalled the LA Lakers' 57-year-old record for any quarter in the play-offs.  The Sixers' 145-point total was also a franchise post-season record.

Ben Simmons claimed the second play-off triple-double of his career after contributing 18 points, 10 rebounds and 12 assists to the victory at Wells Fargo Center.

Joel Embiid, who had been a doubt due to a knee injury, added 23 points and 10 rebounds for the Sixers, for whom at six players scored at least 15 points.
