"I felt like I missed some shots I should have made," he said. "In the second half they did a good job keeping me from getting to the goal."
The Hornets' Anthony Davis struggled from the floor, making four of nine shots for nine points but had 12 rebounds and four blocked shots.
New Orleans also struggled from the free throw line, making 4 of 12, the .333 percentage setting a franchise record.
The Hornets had defeated the Hawks in six of the past 10 meetings and appeared to be in control early, leading 21-10 late in the first quarter. But Atlanta closed on a 12-5 run with Vasquez and Lopez on the bench for the final three minutes, cutting the lead to 26-22.
In the fourth quarter, New Orleans twice cut the lead to two points, the last coming on Vasquez's free throw with 4:14 remaining. But Korver answered with a trey off of a Horford assist to put the Hawks up 87-82 with 3:57 left.
"I think everyone was waiting on (Gordon) to do something, be Superman," Williams said. "That's not what we're about. We're a team and I got to find a good rotation."
NOTES: Smith's 13 rebounds put him over the 5,000 mark for his career. ... Vasquez's nine rebounds left him one short of what would have been his second triple-double of the season. ... Atlanta has two days off before traveling to Detroit, the final leg of a three-game road trip.
