Brandon Ingram had 29 points, 11 assists and eight rebounds, and the New Orleans Pelicans defeated Chicago 123-108 on Wednesday night to drop the Bulls to a fifth straight loss.
Ingram was just two rebounds short of his first career triple-double.
JJ Redick hit six 3-pointers on his way to 24 points, while Hayes had 14 points, 12 rebounds and four blocks to help the Pelicans win for the seventh time in 10 games.
The 6-foot-11 Hayes also continued to rev up the crowd with his above the rim athleticism, be it on a transition dunk or his rejection of Coby White's layup attempt in the final seconds of the third quarter.
Zach LaVine scored 32 for the Bulls, who are in the midst of their longest losing streak this season.
Thaddeus Young scored 18 in his return to the city where he was born.
Chicago led by six early in the third quarter before New Orleans went on a 15-3 run that put the Pelicans in front for good. Ingram scored nine during that surge, starting it with a 3, adding another from deep and then hitting three free throws after he was fouled on a 3-point attempt.
The Bulls have been vulnerable to third-quarter lapses this season.
By the fourth quarter New Orleans widened its lead to as many as 21 points.
Lauri Markkanen scored 14.
Josh Hart, who started for Jrue Holiday, scored 13 points. Lonzo Ball and Nickiell Alexander-Walker each scored 11.
The Bulls host Indiana on Friday night.
