A man died on Saturday after falling from an upper deck at the Atlanta Braves' ballpark, the Major League Baseball team said.
The fall occurred in the top of the seventh inning of the New York Yankees' 3-1 win over the Braves -- as Yankees slugger Alex Rodriguez was walking to home plate to bat amid boos from Braves fans.
Fans seated in the lower section behind home plate where the man fell scattered and paramedics raced to treat him.
"We have received confirmation that the fan involved in an accident at this evening's game has passed away," the Braves said in a statement issued after the contest.
"The Atlanta Braves offer their deepest condolences to the family."
Atlanta Police Sergeant Greg Lyon said police were investigating the circumstances of the fall, but did not immediately identify the man.
Spectator Greg Shiver of Tennessee, who attended the game with his son, told the Atlanta Journal-Constitution that he had just told his son to watch for Rodriguez when he heard "a big thud".
"I saw a guy falling from the top. I grabbed my son and ran for security," said Shiver.
The newspaper said the man had fallen at least 12m.
In 2013, Braves fan Ronald Lee Homer Jnr died after climbing over a railing at Turner Field and leaping to his death in a parking lot in a death ruled a suicide.
A 25-year-old man fell four levels to his death at the ballpark in 2008.
