Tiger Woods' teenage son Charlie hit his first hole-in-one during the final round of the PNC Championship in Orlando, Florida - before Padraig Harrington's son Paddy emulated the feat.
Charlie Woods, 15, holed out at the par-three fourth to send the father-son team into the lead at the tournament, which features 20 major champions playing with a member of their family.
The pair finished Saturday's first round at the PGA-backed exhibition tournament with a share of the lead.
"It was a perfect seven-iron, so just kind of hit it," Charlie Woods told the Golf Channel.
"It was awesome. I didn't think it went in. I don't believe anybody until I go up there and see it."
But the younger Woods' feat was soon matched by another young player making a first career hole-in-one.
Some 30 minutes after Charlie Woods holed out, Paddy Harrington - the 21-year-old whose father is a three-time major winner - aced the eighth hole.
"I've never hit a shot and been that excited before," Padraig Harrington said.
Tiger Woods, 48, is playing in his first competitive event since the Open in July.
