Atlanta has had multiple players get sick during its West Coast trip, though they only missed practices until Wednesday. The latest bug sidelined Horford and Harris. Zaza Pachulia started at center in Horford's place, and even he had to overcome a setback.
Pachulia was cut above his right eye in the first quarter, with blood dripping down the side of his face. He received stitches in the locker room and returned.
With the Hawks hurting on the inside, the Warriors went to work.
Lee led the charge by going at Atlanta's depleted front line, allowing Golden State to play inside-out. He had 14 points and seven rebounds in the first half to help the Warriors take a 54-46 lead.
Golden State withstood several shots from Atlanta.
The Hawks started the third quarter on a 7-1 run to trim the Warriors' lead to two. Ivan Johnson then inadvertently elbowed Warriors second-round pick Draymond Green in the face while going for a rebound late in the quarter.
Green stayed down for a couple of minutes until walking gingerly to the locker room, with Johnson patting him on the chest on the way off the court. The team said X-rays on the right side of Green's jaw came back negative. He later returned.
In the meantime, another rookie helped the Warriors create some separation.
Barnes ignited an 18-7 spurt the lasted through the opening minute of the fourth quarter to put Golden State ahead 73-60. He threw down a put-back dunk that brought fans roaring to their feet, including Warriors owner Joe Lacob sitting in his usual courtside spot, and mixed in a turnaround jumper and a driving layup.
NOTES: The Warriors honored former coach Don Nelson at halftime for his Hall of Fame induction in September. The 72-year-old Nelson, who has an NBA-record 1,335 wins, said he has no plans to get involved in basketball again and is enjoying retirement at his home in Maui, Hawaii. ... The Hawks finish their four-game road trip Friday at Sacramento. ... Warriors C Andrew Bogut will rehab his surgically repaired left ankle in the Los Angeles area during the team's road trip.
