ATLANTA -- Authorities are investigating the death of former Braves and Angels pitcher Tommy Hanson.
Coweta County coroner Richard Hawk said an autopsy began Tuesday, following Hanson's death at the age of 29 on Monday night at Atlanta's Piedmont Hospital.
Hawk said Hanson was found "unconscious and unresponsive" in Coweta County near Atlanta on Sunday. He was initially taken to a hospital in Newnan before being transferred to Piedmont.
Hawk told The Associated Press on Tuesday night "the cause and manner of death are still under investigation."
Hanson, a 6-foot-6 right-hander, pitched for the Braves from 2009-2012, winning at least 10 games each season.
