IT may have been a triumphant day for Rory McIlroy, but his dad Gerry was also a winner.
Ten years ago the 25-year-old superstar's father and three of his friends put £100 (€125) at 500/1 on Rory winning the major by the age of 26.
Yesterday they were laughing all the way to the bank as their prediction came true and Ladbrokes agreed to pay out £180k. He can now claim £45,000 (€56,000) from the bookies after Rory finished on the 18th green at Royal Liverpool last night two shots ahead of Sergio Garcia and Ricky Fowler.
"I don't think it matters to my dad so much anymore, but hopefully the bet still stands - I'm not quite sure, but if it does that's great," said Rory after sinking his final putt.
The Holywood native's win at the weekend has seen him become the first European to win three different majors since the Masters was founded in 1934.
He won the US Open in 2011 and the PGA Championship in 2012. Even golfing legends such as Nick Faldo and Seve Ballesteros won only two of the four.
Rory dedicated his win to his mother Rosie McDonald.
"This is the first major that my mum has been here for that I've won, so this is for you," he said during his acceptance speech.
Rory also thanked the crowd for their support, particularly as he is a Manchester United football fan in Liverpool territory.
"The fans turned out in their thousands this week, it's been a pleasure to play for you all," he said.
Reflecting on his success yesterday, Rory said his win hadn't hit home yet.
"It's a pretty big achievement and it's not going to sink in for a while, but it feels pretty incredible right now," he said.
