Oklahoma City: Kevin Durant scored 32 points and Russell Westbrook added 20 on Thursday as Oklahoma City beat Chicago 107-95 to remain the only NBA team with a perfect home record this season.
The Thunder have won all 13 of their home games so far this campaign.
With their eighth straight victory, and their 16th in 17 games, they improved to 21-4 overall, the best record in the NBA.
Joakim Noah had 23 points and 12 rebounds for the injury-depleted Bulls, who dropped their fourth straight game.
Taj Gibson scored 16 points and D.J. Augustin added 15 for the Bulls, who were without Luol Deng and Kirk Hinrich and saw Jimmy Butler depart early with a right ankle injury.
British forward Deng sat out with a sore Achilles tendon that saw him miss four other games this month.
Guard Hinrich missed his fourth straight game with a back injury.
The Bulls are now 3-11 since losing former NBA Most Valuable Player Derrick Rose to a knee injury that required surgery last month.
