Federal club golf professional Joshua Price happened to be recording the moment Daly, 54, got to the 11th tee box in Glen Allen, Virginia, to strike at Monday's Bone Frog Open in favor of fallen US Navy SEALs.
The two-time great champion stood confidently upright with no shoes, no hat, his shirt unbuttoned, and sent the ball straight for the hole about 400 feet away.
Seconds later – cheers and high fives.
Daly turned and commented, "That makes 11 of them mother …" on a blemish, but quickly catching herself.
Watch the moment:
The professional golfer revealed last month that he was diagnosed with bladder cancer. Daly announced that he had undergone a procedure to remove the cancer, but said there is a good chance it will come back.
"Luckily for me they noticed early on, but bladder cancer is something I don't know all the details about. But it doesn't look like it's going away. We'll just see what happens. Maybe there is a miracle," Daly said.
Golfpro Price, who witnessed the moment, told CNN that Daly appeared to be doing well and cheerfully and the 54-year-old's swing looked the same as ever.
"It's just silky smooth. The man is an absolute machine, it's unbelievable," said Price, pointing out that it was Daly. fun for everyone on the course. "Just a great person."
