Rory McIlroy was not the only winner at the British Open overnight.
The BBC said McIlroy's father, Gerry, and three of Gerry's friends placed a combined bet of £400 (NZ$786) in 2004 on McIlroy winning the British Open before he turned 26.
McIlroy was 15 at the time of the wager and is now 25.
The odds were 500-1, so the syndicate looks to collect £200,000 (NZ$393,000) now that McIlroy has lifted the claret jug.
He won by two strokes over Sergio Garcia and Rickie Fowler.
In another twist of fate linked to McIlroy's win.
His British Open victory came on the same day that his former love interest, tennis star Caroline Wozniacki returned to the winner's circle.
The two were engaged but broke up two months ago.
Danish player Wozniacki won the Istanbul Cup women's singles final, beating Roberta Vinci, of Italy, in two sets, 6-1 6-1.
