One pegged the manís fall over a railing at close to 65 ft. before he eventually hit the pavement outside the stadium.
"There was an accident earlier tonight at Turner Field with a spectator falling from the upper level," the Braves said in a statement. "The Atlanta Police Department are investigating and we refer all media inquiries to them at this time."
The man was identified as 30-year-old Ronald Homer of Conyers, Ga. He was transported to hospital while investigators remained on the scene.
Connie Homer told the Associated Press that her only son, who was a life-long Braves fan, had talked to her on his cellphone during the rain delay.
"It appears that the male fell from an upper-level platform to a secured lot below," Atlanta Police spokesman John Chafee said. "At this time, there is no indication of foul play and the fall appears accidental."
Details of how the fall occurred remained unclear Monday night and the rain-delayed game was eventually completed.
In 2008, a 25-year-old man was killed at the same stadium after plunging an estimated 150 ft. when he slipped and tumbled over a banister before landing at field level.
