Six people were injured as thunderstorms and lightning strikes caused havoc at the US PGA Tour's season-ending Tour Championship.
Leader Justin Thomas managed just five holes of his third round before play was called off for the day after storms struck Atlanta's East Lake Golf Club on Saturday afternoon.
But the halt did not stop people on the course being injured.
"At 4.45 p.m., there were two lightning strikes...a tree near the range/15 green/16 tee was hit, and debris from that strike injured four people," the PGA Tour said in a statement.
"(Emergency personnel) tended to those fans and two others immediately and transported them from the property via ambulance for further medical attention.
"Our latest report is that their injuries do not appear to be life threatening."
The strike occurred 28 minutes after the day's play was halted when thunderstorms popped up over the course, PGA Tour rules official Mark Russell said on the NBC broadcast.
PGA Tour officials made a confusing decision not to bring tee times forward despite the forecast storms.
Play was suspended at 4.17pm local time - with the resumption scheduled for 8am local time on Sunday and the final round to be played in the afternoon.
When players were taken off the course on Saturday, Thomas topped the leaderboard at 12-under-par and even with the scorecard through five holes.
Rory McIlroy and world No.1 Brooks Koepka are a shot behind at 11 under while Xander Schauffele is 10 under - the trio also managing to complete just five holes on Saturday.
Adam Scott leads the Australian contingent and is five under for the week having mixed a birdie with a bogey in his first seven holes in the third round.
Marc Leishman is the only other Australian in the field but dropped another two shots during a 72 that sank him to five over and near bottom of the elite 30-man field.
The winner of the season-ending play-offs event will collect a record first prize of $15 million.
