Those three big-race wins tell a story on their own. A Class 1 at Epsom Downs in June 2024, another at York in August 2024, and a third at Goodwood in August 2025 — three of the most prestigious and recognisable tracks in British racing, all checked off inside 15 months. Epsom is famous worldwide as the home of the Derby. York is widely regarded as the sport's most atmospheric summer venue. Goodwood, set on a hillside in West Sussex, hosts some of the most coveted prizes of the flat season. Winning at one of them would be a career highlight for many stables. Winning at all three, this early, is genuinely remarkable.
The day-to-day numbers back up the headline results. Over the last 12 months the yard has sent out 44 winners from 378 runners — that's 12%, or roughly 1 in every 9 races. What makes that more interesting is that a year ago, the win rate sat at 9%. The improvement is not a fluke of a lucky afternoon; it's a sign that the operation is learning and strengthening as it goes. Their most trusted jockey is Jason Hart, who has partnered yard runners to 26 wins from 218 rides together — again, 12%, or about 1 in 9 — a reliable and well-worn working relationship built race by race.
One combination worth watching is the yard's partnership with Liberty Coach, who has won 4 of the 22 races they have run together. That kind of record — nearly 1 win in every 5 outings — points to a horse the team knows inside out and places with real confidence. In a sport where patience and precision matter enormously, that sort of consistency is no accident.
Two years in, 87 winners, three of the sport's biggest stages already visited. John & Sean Quinn are not building towards something — they are already there.
