Rory McIlroy’s dad set to collect big after 10-year-old bet pays off

Gerry McIlroy is set for a big payday after his son Rory won the British Open today.

The elder McIlroy and three friends each placed a £100 ($182) bet at odds of 500:1 10 years ago that Rory, now 25, would win the Open before he turned 26.

Their foresight is set to pay off to the tune of £200,000 (A$363,798), while the champion himself will pocket five times that for winning the third major of his young career.

Another punter earned £80,000 (A$145,519) after placing a bet of £200 (A$363) at odds of 150/1 in 2005 that McIlroy would win the open before 2015.
