Marco Belinelli had 18 points, Mickael Pietrus added 17 and Troy Hudson 16 for Golden State, which beat Los Angeles 111-110 on Tuesday night.
Derek Fisher and Vladimir Radmanovic had 12 points apiece for the Lakers, and Andrew Bynum, Chris Mihm and Kobe Bryant added 11 each.
The Warriors outscored the Lakers in each quarter and looked like the offense that was second in the league with 106.5 points per game last season.
Golden State used a 10-0 run midway through the second quarter that began with Belinelli's three-point play to pull to within 35-33. Pietrus made two free throws and Hudson scored on a layup to give the Warriors a 37-35 lead.
Belinelli's 3- pointer with a little under 7 minutes left in the first half gave Golden State the lead for good, and the Warriors led 63-56 at the break.
Pietrus was taken to the locker room in the third quarter with a strained lower back. He did not return and is day-to-day.
Baron Davis, Andris Biedrins, Monta Ellis and Al Harrington did not play for the Warriors. Davis was out for rest, Biedrins is nursing a sore left big toe and Ellis missed his second successive game due to a sprained neck.
Kwame Brown, Lamar Odom and Maurice Evans sat out for Los Angeles. Brown is recovering from surgeries on his left ankle and right shoulder did not play, Odom has an injured left shoulder, and Evans strained his left hamstring in the previous game Tuesday.
