The former Atlanta Braves third baseman, 41, whose 19-year career ended in 2012, used social media to explain the fire Wednesday evening.
"Tried to so my daily chores and cleaned out the fireplace. Went and dumped the ashes. All's good, right? Nope. Set the woods on fire," he wrote on his Twitter account.
Roswell Fire Department Deputy Chief Paul Piccirilli said it required one fire engine to extinguish the fire, which burned an area about 30 feet in diameter.
Firefighters were on the scene for about 45 minutes, the Atlanta Journal-Constitution reported Thursday. There were no injuries.
A later Twitter message from Jones thanked the firefighters for their quick work, the newspaper added.
