BRYSON DECHAMBEAU roared "are you kidding me?" after hitting a hole-in-one over his $2 million (£1.6m) Texas mansion.
The American, 31, set himself the ambitious challenge earlier in the off-season.
DeChambeau has a putting green in his back garden, and on each day attempted to hit the ball in from the front of his house.
On day one he gave himself a single try, on day two, two tries - and so on - increasing his number attempts each day.
After more than two weeks of trying, DeChambeau achieved the amazing hole-in-one on his 14th attempt of day 16.
In what was his 134th try overall, the two-time Major champion found the hole.

After realising what he had done, DeChambeau yelled "are you kidding me?" in pure delight.
He then ran around pumping his fists and laughing in disbelief, tossing his hat into the air as he wheeled away in celebration.
After reaching the hole, DeChambeau kissed the ball before tossing it away, screaming: "Let's go baby!"
The clip, posted to the golfer's X account, has been viewed more than four million times - with plenty of fans buzzing at DeChambeau's feat.
