The BBC's Andrew Cotter first reported on that gamble on Twitter, writing: "So just to confirm - 10 yrs ago Gerry McIlroy & three friends put £400 at 500-1 on 15 year-old Rory to win The Open before he turned 26."
Gerry told Irish Golf Desk in 2006: “We put the bet on when he was 15. They would only let us lay £400 — £100 each. But the bookies are [getting to know] Rory [now]."
And since Rory won this year, his father and his friends just pocketed about $85,000 per person.
Cotter says the McIlroy's don't really need the money, the prize for winning The Open is nearly triple the bet's payout. It's more about Rory's legacy.

His victory Sunday makes him the third youngest golfer to win three out of the four major tournaments. The two youngest: Tiger Woods and Jack Nicklaus — pretty good company. (Via Getty Images)
To win, McIlroy was able to stave-off American Rickie Fowler and Spaniard Sergio Garcia, both of whom finished just two strokes behind. Rory shot -17 for the tournament. (Via Getty Images)
