ATLANTA — Six people were hurt when lightning struck a golf course twice on Saturday during the third round of the Tour Championship.

The strikes hit the East Lake Golf Course as fans and golfers waited for bad weather to pass. The tournament’s organizers responded by stopping play for the day, pushing the round to Sunday, and said the injuries did not appear to be life-threatening.

Ambulances were summoned to an area between the 16th tee and the driving range around 4:45 p.m. Eastern Daylight Time. One of those hit was Billy Kramer, a resident of Dunwoody, Ga., and the owner of N.F.A. Burger, one of the tournament’s food vendors. He was in a cart, driving to collect more supplies for his stand off the eighth fairway, when a lightning bolt struck a pine tree just off the path where he was driving.

“It was like a sonic boom,” said Kramer, who was seated on the grass being treated by medical personnel as he waited to be loaded into an ambulance.
