Four years into his training career, Daniel William O'Sullivan is still waiting for that first winner. Nineteen runners this season, nineteen runners without a trip to the winner's enclosure — it's a stark number, and an honest reflection of where he currently sits in the pecking order of British racing.Based on TrackLab's analysis

TrackLab's trainer breakdown
That said, getting horses to the track consistently is the foundation everything else is built on. Plenty of trainers take several years to land their first winner, and the fact that O'Sullivan has kept a yard running for four years speaks to a certain persistence. The breakthrough, when it comes, will mean something.
For now, he remains one to watch rather than one to back — a trainer building experience in the most unforgiving classroom there is.
