Rory McIlroy's father Gerry stands to win £100,000 if Rory wins Open Championship
Rory McIlroy can win £975,000 with victory in the 143rd Open Championship at Royal Liverpool on Sunday, but his father would also have another reason to celebrate.
Ten years ago 25-year-old McIlroy's dad Gerry and three friends each placed a £100 bet at odds of 500/1 that his son would become Open champion before he turned 26.
The Northern Irishman has won each of his two majors by eight shots, the first in the US Open at Congressional in 2011 and the second in the US PGA Championship at Kiawah Island the following year.
However, in 2011 McIlroy also took a four-shot lead into the final round of the Masters at Augusta before collapsing to a closing 80, while he himself won the BMW PGA Championship at Wentworth this year from seven shots behind with 18 holes remaining.
