The Atlanta Braves will hold a ceremonial laying of the first bricks on Thursday at the new SunTrust Park.
The ceremony will likely include updates on ballpark construction.
The event will feature an honorary mason, Eustis Morris, who the Braves said laid bricks at Atlanta-Fulton County Stadium and Turner Field.
Braves Chairman and CEO Terry McGuirk, President John Schuerholtz, hall of famer Hank Aaron and current Braves first baseman Freddie Freeman are expected to attend.
Also expected are the CEO of SunTrust, Bill Rogers; Cobb Commission Chairman Tim Lee and Commissioners JoAnn Birrell, Lisa Cupid, Bob Ott and Bob Weatherford.
The event starts at 10 a.m., but the ceremony, at an active construction site, will not be open to the public.
