Patrick Mullins equalled the long-standing record for the number of winners by an amateur jockey in a calendar year in Ireland when Union Dues provided him with his 72nd victory of 2012 at Navan.
Billy Parkinson was the last amateur to ride so many, way back in 1915.
Union Dues quickened up smartly to beat the Ted Walsh-trained odds-on favourite Champagne James in the bumper to provide Mullins' father, Willie, with a treble.
Mullins, who rode his first winner as a 16-year-old in 2006, was thrilled with the milestone. "It's magic, it's a relief to get it as it would have been a shame to get so close and then not get it," he said.
"I ride a horse in a maiden hurdle at Downpatrick on Thursday and he could be the one to break it.
"This lad impressed me the last day when Tony (Mullins) had him but to be honest I didn't think he'd beat Ted Walsh's horse.
"The gears he showed there, it will be all about Cheltenham now."
His father added: "He's been riding fantastic all year and has huge commitment. He thinks his own way through his races. He very seldom makes a mistake."
